GROUNDING INSTRUCTIONS

• FOR ALL GROUNDED CORD CONNECTED TOOLS:

• In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances. Do not modify the plug provided if it will not fit the outlet, have the proper outlet installed by a qualified electrician. Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation, having an outer surface that is green with or without yellow stripes, is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipmentgrounding conductor to a live terminal. Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Use only 3-wire extension cords that have 3-prong grounding plugs and 3pole receptacles that accept the tool’s plug. Repair or replace damaged or worn cord immediately.

Drill Alignment

The alignment port is located on the left side of the XT-3000.

The first stage to sharpening a drill starts with the alignment process. In the alignment process, you will go through a few necessary steps prior to sharpening. Setting the material removal amount, adjusting the alignment tube to produce desired relief amount. Use the Darex easy align to set the drill to length and time the cutting edge.

Setting Material Removal

Amount

1. Rotate the material removal knob to adjust the amount of stock you want to remove from

the end of the drill. Stock removal ranges from approximately .010 .030. Remove more material if the drill is excessively worn or damaged. Remove less material if you are renewing the drill.

2. Rotate the material removal knob clockwise to decrease the amount of material removal

Tip: Sharpen drills

on Minimum MTO to achieve longer wheel life.

or counterclockwise to increase material removal.

Setting Alignment Tube for Desired Heel

Relief

To increase or decrease the amount of heel relief produced during sharpening, change the position of the alignment tube.

1. Lift the alignment locking lever.

This will

allow you to rotate the alignment tube in either direction.

2. To increase heel relief, rotate the alignment tube counterclockwise.

proper length

1. Holding the chuck in a horizontal position insert the drill into the appropriate sized chuck. (Sizes are on the cam)

2. Rotate the chuck knob clockwise, which closes the chuck jaws onto the drill. Then slightly loosen the chuck jaws by rotating the chuck knob counterclockwise, about ½ turn. To determine how tightly the drill should be held during the alignment process, the drill should slide freely and drop out when the chuck is held in a vertical position.

Timing the cutting edge

3. Insert the chuck and drill into the alignment tube.

Align the cam dogs with the slots.

The cam dogs should bottom out against the slots.

Allow the drill to protrude approximately 2 inches as shown.

Drill point should be touching the end of the pusher shaft cap.

Drill Sharpening

The Sharpening fixture is located on the right side of the machine.

Mounting the Sharpening fixture

1. Rotate the locking lever so the flat edge is at the top, horizontal and in a straight line with the base casting.

2. Position the sharpening

fixture so that the 2 location holes on the base of the alignment fixture are aligned with the 3/8 dowel pins.

3. After sharpening fixture is in place, rotate the locking lever clockwise until snug. This will secure the fixture to the base.

Adjusting the Point Angle

You must loosen the sharpening fixture and slide the point angle indicator to the desired degree.

1. To loosen, pull the locking lever towards you.

2. Place fingers on each

side of the sharpening pivot base casting.

3. Gently slide base

casting in either direction to align the angle indicator with the desired point angle degree.

4. Secure the selected point angle position by pushing the locking lever away from you until it stops.

5. Before sharpening, make sure the sharpening

fixture is secure and no longer slides in either direction.

Power up machine

To turn the machine on, push the top of the rocker switch. The machine will power up and the grinding wheels will begin to rotate.

Sharpen

1. To make sure the drill clears the wheel, push the sharpening tube all the way to the left before inserting chuck.

2. Insert the chuck with the thickest part of the cam touching the swing bearing.

3. Release sharpening tube very slowly.

4. With slight pressure towards the grinding wheel, rotate the chuck 360 degrees, several times in a clockwise direction. To achieve an efficient and balanced sharpening on both cutting edges, avoid stopping when the drill is in the grind. Do not reposition your hand in mid-sharpening, wait until the drill rotates off the wheel. Continue rotating the chuck in 360 degree rotations until the grinding noise is minimized to a near silence.

5. Before removing the chuck, push the sharpening tube to the left, remove chuck. Release sharpening tube slowly.

Drill Point Splitting

The Point Splitting Port is located in the center of the machine.

Approximately 3-7° rake is created, producing a drill with a self-centering point. Its advantages are the ability to reduce thrust and eliminate walking at the drill point. This is a distinct advantage where drill bushings/fixtures are not used.

Splitting

POINT SPLIT DIAGRAMS

DEPTH OF SPLIT DIAGRAM

Past Center To Center Below Center

Upon completion of the sharpening procedure, Do Not loosen the drill in the chuck. Insert the chuck into the point splitting port. Align the cam dogs with the slots on the point split tube. Let the weight of the chuck ease the drill down and onto the grinding wheel. With slight pressure, be sure the chuck stays seated in the point splitter.

When the grinding noise is reduced to near silence pull the chuck out about 1/2 way and rotate it 180 degrees to split the opposite side of the drill

point. NOTE: Do not force the chuck into the grinding wheel or damage to the drill or wheel may occur.

Adjusting the Depth of Split

The depth of split can vary from drill

manufacturer to drill manufacturer. The point split depth adjustment feature designed on the XT-3000 makes it easy to mimic multiple split styles. The point split depth adjustment lever is attached to the point split chuck tube. As you move the lever, it backs the chuck tube away from the wheel or moves it closer into it.

1. Located on the underside of the point splitter is the point split depth adjustment lever.

2. To increase the depth of split, push lever to the left toward the + sign. This will allow the drill to travel deeper into the wheel, increasing the depth of split.

3. To decrease the depth of split, push the lever to the right toward the – sign. This will back the drill away from the wheel.

NOTE:

deeper than desired, you will have to regrind the drill beyond the over split portion before splitting again.

Adjusting the Split Angle Rotation

Typically the split angle of a drill is 120° - 130° from the cutting edge. By increasing the rotation of the split angle, the split portion of the drill meets the cutting lip at a greater angle, which will give the drill more strength and durability. This added split angle creates a pointed profile at the very center of the drill, producing a selfcentering effect and reduces drill point walking at the start of a hole.

Chuck Information

A regular maintenance program should be set up for each chuck. Keeping your

chuck clean and grit free will help maintain drill concentricity and lengthen the life

of your chucks. For detailed cleaning instruction, See Maintenance page 22.

XT-3000 CHUCKS

The XT-3000 jaw chuck system was designed with accuracy and simplicity in mind. As a result, the XT-3000 chuck allows you to cover a large diameter range of drills without the aid of individual collets. You can quickly change from the largest drill diameter to the smallest in seconds. The accuracy of the chuck will produce drills that exceed ANSI, NAS 907 & & ISO 10899 standards. The various chucks and accessories have drill diameter capabilities that range from .059” – 1.1875” (1.5mm to 30mm).

Make sure large drills are secure after tightening the chuck.

Morse Taper drills:

To secure a Morse Taper drill in the chuck, it is necessary for the drill to have a minimum flute length of 4.000 inches. The taper will then be free from the grasp of the jaws, eliminating interference with the larger tapered shank. The other option for holding these types of drills is a split bushing. Bush the body of the drill up to or larger than the interfering diameter.

End Mill shank drills:

Typically, an end mill drill has a shank diameter larger than the body of the drill. Some End Mill shank drills can be sharpened on the XT-3000, depending on the length of the flute verses the length of the shank.

CHUCK DISASSEMBLY &

MAINTENANCE

chuck assembly should be disassembled and cleaned periodically.

The use of a dust extraction system

during grinding will help reduce the

amount of maintenance, however, the

1. Place flats of chuck body into a vice, do not

over tighten.

XT-3000 WHEEL INFORMATION

The Darex XT-3000 comes equipped with electroplated CBN (Cubic Boron Nitride). Optional Diamond wheels are available. The wheel comes

installed on your sharpener ready to sharpen drills.

Sharpening with an electroplated CBN (Cubic Boron Nitride) or Diamond grinding wheel reduces grinding cost and improves quality of the finished product. These results are obtained because the grinding material is super abrasive. The CBN is second only to diamond in hardness. In fact, CBN has twice the hardness and four times the abrasion resistance of an aluminum oxide grinding wheel. The CBN and Diamond wheel last longer; the grinding process is faster and less grinding time is lost due to wheel breakdown & maintenance.

WHEEL MAINTENANCE

These wheels are maintenance free from truing and dressing but will need to be cleaned

periodically.

the machine using a lock out tag out procedure. After removing the wheel from the

sharpener, saturate the wheel with any type of oil-less solvent, such as Automotive Brake Cleaner. and lightly brush the saturated wheel, loosening the impacted grinding particles. Re-saturate the wheel to flush out any loosened debris. Do not use any type of dressing tool on these wheels. Damage to surface will occur and greatly shorten the wheel life.

NOTE:

discolor or burn, the wheel life may be exhausted and the wheel will need to be replaced.

Disconnect the power from

It is helpful to use a soft bristle brush

If after cleaning wheel, the drills still

are available if carbide is to be sharpened on this machine.

WHEN TO REPLACE THE

WHEEL?

Eventually, the long-life electroplated wheel in your XT-3000 will wear out. Indicators that a wheel change is necessary are: a drop in performance such as drill burning or excessively slow sharpening time. Inspect the wheel for abrasive quality. A worn wheel will appear smooth. If it is necessary, replace the worn wheel(s). New wheels will initially produce a coarser grind. However, this aggressiveness will disappear after approximately the first one hundred drill sharpenings. Under normal use, you should experience 4-6 thousand drill sharpenings from each new wheel. *Darex does not re-plate or recommend replating the grinding wheels. For replacement wheels, contact your Darex distributor or Darex .

HOW TO CHANGE A WHEEL

1. Unplug unit from power supply

and use a “LOCK OUT” “TAG OUT” procedure.

Wheel cleaning:

These wheels are maintenance free from truing and dressing but will need cleaned periodically. After removing the wheel from the unit, saturate the wheel with any type of oil-less solvent, such as Automotive Brake Cleaner. It is helpful to use a soft bristle brush and lightly brush the saturated wheel, loosening the impacted grinding particles. Re-saturate the wheel to flush out any loosened debris.

Always clean a brand new wheel before using. If after cleaning wheel, the drills still discolor or burn, the wheel life may be exhausted and the wheel will need to be replaced.

Recalibrating Material Removal

After a wheel change, verify and/or recalibrate material removal.

Use a 3/8 HSS standard twist drill, measure the length of drill before sharpening.

1. Rotate material removal knob to maximum take off.

2. Align drill as though you intend to

sharpen it. Follow Alignment steps on page 9.

3. Once drill is set to

length, aligned and captured in the chuck, securely remove from alignment port.

4. Measure the amount of drill protruding from the end of the chuck to the tip of the drill, before sharpening.

5. The length of the drill protruding from the top of the chuck should measure .970-.980 (24.63 mm - 24.89 mm)

Calibrating the Material removal knob

1. Located at the rear of the machine base, you will find a small access hole.

2. Insert a 3/16 Allen wrench into the access hole.

3. To advance the pusher shaft cap, reducing the amount of drill stick out, rotate the wrench clockwise.

4. To retract the pusher shaft cap, increasing the amount of drill stick out, rotate the wrench counterclockwise.

Each ¼ turn will adjust .010 (.25 mm) or one full turn will adjust .04 (1.0 mm). After adjusting the pusher shaft assembly, realign the drill and re-measure the amount of stick out. Repeat the steps 1-4 until the drill protrudes .970-.980 in length. (24.63 mm - 24.89 mm)

General Maintenance

Chuck Maintenance

Chuck maintenance is very important. To sustain the life of your chucks and to maintain precision lip height concentricity, clean the chucks on a regular basis. Some tools are necessary to disassemble the chuck, You will need: Wrench PP16480SF (Optional)

Disassembly:

The use of a dust extraction system while grinding will help reduce the amount of maintenance necessary, however, periodically the chuck assembly should be disassembled and cleaned.

1. Place flats of chuck body into a vice.

2. Place chuck wrench on dogs of chuck knob assembly.

3. Rotate wrench counterclockwise to remove chuck knob/jaw assembly from chuck body.

4. Using a 2.5 mm hex wrench, remove set screw.

5. The internal pieces must remain keyed in order to remove the closing screw from the chuck knob assembly. Insert the

2.5 mm wrench, into the set screw hole.

6. Rotate chuck knob counterclockwise until the wrench reaches the top of the slot.

7. Remove wrench and reinsert into the set screw hole above the slot.

General Maintenance

8. Rotate the chuck knob counterclockwise until the closing screw exits the knob assembly.

9. The chuck knob assembly does not come apart from this point.

Chuck Cleaning: Once disassembled, clean all parts with a type of oil-less solvent such as Automotive Break Cleaner.

Chuck Re-assembly:

Reassemble in reverse order.

Point Split Tube Cavity:

Routinely vacuum and using a dry cloth, wipe out the inside of the Point Split Tube. Removing grinding dust will help produce consistent split point drills by retaining the ID dimensions of the tube and reducing early wear.

Sharpening Tube Cavity:

Using a dry cloth, wipe out the inside of the brass tube, removing grinding dust. Over time it may be necessary to replace the sharpening tube. The sharpening tube is threaded into the housing using right-handed threads. To remove, rotate tube counterclockwise using a spanner wrench. Replace as needed.

Wheel Housing Cavity:

While grinding wheel is out of machine and before replacing wheel, vacuum out wheel housing and wipe around the hub area.

External Machine Castings:

Wipe down external machine castings with a mild household cleaner.

Grit Tray/Vacuum Port Connection: Grit tray

At the back of the machine, located underneath the grinding motor is the grit tray. Drill grindings will accumulate inside the grit tray. The grit tray has a magnetic liner to attract and hold these dust particles. Do not let the tray become more than 1/3 full. To remove tray, unscrew brass thumb screw. Remove tray and dump contents. Wipe excess dust from the tray with a rag.

Vacuum Port Connector (Optional)

The grit tray has a knock out plug that can be removed by hand and replaced with the vacuum tube (SA16030TA). Use this port to connect a vacuum hose to the XT3000. This method of extracting dust particles from the machine will keep it cleaner and is recommended.

Oil Lubrication:

Never use an oil-based lubricant on any part of this machine! Oil-based lubricant will collect grinding dust particles. Powdered graphite may be applied to any sliding parts located on the machine.

Congratulations on the purchase of your Darex XT-3000 Large Drill Attachment. (21 mm—30

mm) As part of the assembly (see picture from left to right) you should have a SA16565XA Large drill alignment, SA16575CA Sharpening fixture,

and SA16500TA Large Drill Chuck. By now you are familiar with the ‘quick disconnect’ feature of your XT-3000. Start by placing the Large Drill Alignment on the top of your XT-

3000. Rotate the ‘Docking Lever’ clockwise to securely lock the fixture in place. In a similar manner, remove your current sharpening fixture and replace it with the Large Drill Sharpening

The alignment is adjusted by rotating the black lever located on the front of the alignment fixture. As per the decal, rotating the lever towards the operator will reduce the amount of relief ground onto the drill and pushing the lever away from the operator will increase the relief. Placing the pin at the midway point on the decal is a good starting place for 118° drills. For 135°-150° drills start with the alignment 2 marks towards the operator. You can set the alignment at any setting necessary to achieve the amount of relief desired.

Place the drill in the chuck and turn the chuck knob clockwise until the drill slides freely through the chuck jaws. Next slide the Chuck and drill into the alignment rotating the chuck until one of the

the outer edge of the cutting lip is touching the pins in the setting fixture. Firmly tighten the chuck by turning the knob clockwise while the chuck is still in the fixture. Remove the chuck and drill. The drill is now aligned and set to length to the chuck cam for the necessary grinding.

Slide the chuck into the Sharpening fixture and rotate the Chuck clockwise applying slight pressure into the wheel. It is also necessary to keep the cam up against the swing cam follower bearing.

Try to sharpen the drill in such a manner that the drill is off the wheel before you reposition your hand on the chuck.

Grinding time will vary depending on wheel condition and amount of material removal but it should require a minimum of 8-10 rotations.

NOTE: The MTO drill stop setting is adjustable using a 5/32” or 4 mm hex key if you think more or less material removal is desired.

Please Note, you do not have the ability to split drills from 21 mm to 30 mm on the XT-3000.

By now you are familiar with the ‘quick disconnect’ feature of your XT-3000. Begin by removing the current sharpening fixture and replacing it with the X-Y table. Secure it in place by rotating the ‘Docking Lever’ clockwise. In a similar manner, lock the Countersink Attachment to the top of the machine.

It is now necessary to determine the shank diameter of the tool that will be sharpened and place the corresponding collet into the Countersink Attachment.

To do so slowly rotate the spindle clockwise until the Spindle Lock engages the spindle.

Now unscrew the Draw Tube assembly. Place the correct collet in the end of the Draw Tube and replace the Draw Tube assembly and tighten 3 or 4 revolutions. Should you need a collet size other than the ones provided, you may order them from Darex . (1-800-547-0222)

Slide the cutting tool into the spindle leaving approximately 1” or more of the tool exposed. Loosen the Alignment Thumb Screw and rotate the Alignment Arm assembly around until the dowel pin intersects both the cutting edge and the heel simultaneously.

Tighten the Alignment Thumb Screw. Rotate the Draw tube assembly clockwise to tighten the tool in the spindle. Return the Alignment Arm to its original position and release the spindle lock pin by pulling up and turning the pin 90°. The cutting tool is now oriented to the spindle cam and is ready to be sharpened.

BRAD POINT ATTACHMENT

LEX200

Congratulations on the purchase of the Darex XT3000 Brad point Attachment. (LEX200) This attachment consists of 2 pieces, 1 Sharpening Fixture, SA16900BA and 1 - 3mm – 12mm Chuck, SA16916TA. (The 12mm – 21mm Chuck, SA16918TA is available as an optional accessory) Both components are laser marked with a Brad Point icon to minimize confusion with other XT3000 attachments.

SETTING UP:

To sharpen a Brad Point, you will have to remove the standard sharpening fixture and replace it with the X-Y Table (LEX100). The Brad Point Attachment works in conjunction with the X-Y Table. By now you are familiar with the ‘quick’ disconnect feature or your XT-3000. Begin by removing the current sharpening fixture and replacing it with the X-Y Table. Secure it in place by rotating the Docking Lever CW. In much the same manner, secure the Brad Point Sharpening Fixture to the X-Y Table.

Should the pilot of the step drill need resharpened, do so, just as you sharpen a standard twist drill. Having the exploded view drawing handy will be beneficial at this point.

SHARPENING THE STEP

SETTING UP:

To sharpen the ‘step’ on your step drill, you will have to remove the standard sharpening fixture and replace it with the X-Y Table (LEX100). The Step Drill Attachment works together with the X-Y Table.

Rotate the Docking Lever CCW to free the standard sharpening fixture, then remove. Place the X-Y Table on

ALIGNING THE DRILL:

Place the drill in the chuck and tighten chuck by rotating the chuck knob CW. Stop just before the chuck jaws make contact with the drill. Make sure the drill still slides easily through the chuck. Place the Chuck in the Alignment fixture until the shoulder of the chuck stops against the alignment.

Rotate the Chuck until one of the alignment dogs rests firmly against the Alignment. Rotate the Pawl Locating Cam until the arrow lines up to the major diameter of the drill. As indicated by the logo on the Timing Arm, rotating it will have an impact on the amount of relief ground on the drill. Unless the drill is intended for a unique material, it is our recommendation that it stay in its normal location. Push the drill through the chuck until the pilot starts to pass through the Alignment. Slide the Length Setting Pawl until it almost touches the pilot. Continue to slide the drill through the chuck until the major diameter stops against the Length Setting Pawl.

With the XT-3000 Sharpening Fixture making sure the drill is clear of the grinding wheel. Using both the X and Y axis knobs, position the drill close to, but not touching the wheel.

LEX300

Congratulations on the purchase of your Darex XT-3000 90°-120° Sharpening Attachment. As

part of the assembly you should have a Sharpening fixture (SA16995XA) and Drill Chuck (SA16890TA) range 3mm to 12mm. (SA016880TA

12mm to 21mm chuck available as optional accessory.)

By now you are familiar with the ‘quick disconnect’ feature of your XT-3000. Start by replacing the current fixture with the 90°120° attachment.

Set your desired point angle by pulling the red Pivot Lock Lever (counter clockwise) towards the operator

and

sliding the fixture across the base plate to the desired point angle. Lock the fixture by returning the red Pivot Lock Lever to its original position.

Use the XT-3000 alignment tube to align the drill in the same manner that you are accustomed to. If the desired point angle is 90°, the alignment tube should be positioned at 118°. For other angles using this attachment, walk the alignment tube towards or past 135° until the correct chisel edge is produced.

Remove the Chuck.

Gently slide the Chuck into the Sharpening fixture. While keeping the Swing Cam in contact with the Swing Cam Bearing, apply slight pressure into the Grind wheel and rotate the chuck clockwise. Try to sharpen the drill in such a manner that the drill is off the wheel before you reposition your hand on the Chuck Knob. Grinding time will vary depending on wheel condition and amount of material removal. It should require a minimum of 8-10 rotations. NOTE: If your drill does not touch

the wheel, an adjustment to the Swing Bearing Assembly will need to be made. Loosen the Swing Bearing Assembly located on the Pivot Base Casting. Rotate the Swing Bearing Assembly until the locating dot is positioned at 12oclock.

This bearing assembly is eccentric. The swing cam on the chuck rests and rides on this bearing. When rotated, the relationship between the chuck cam and the bearing change the starting and stopping point of the drill bit. Depending in which direction you rotate the bearing you will move tip of the drill either closer to, or further from the angle of the grinding wheel. This will change the amount of material removed from the end of the drill. To increase the amount of material removed, slightly rotate the bearing clockwise.

To decrease the material removed rotate the bearing counterclockwise.

After adjusting, be sure to retighten, securing the Swing Bearing Assembly. Re-sharpen the drill and verify the corrected amount of material has been removed. If incorrect, repeat procedure until the desired amount has been removed. Approximately .010 should be the total amount of material removed during sharpening.

Material Take off Adjustment for SA16401TA (1.5-7mm Chuck):

Small diameter bits have a high possibility of breaking if too much pressure is put on them. For this reason, it is critical to follow all of the safety warnings in the XT 3000 User’s Manual. In particular, it is very important to wear ANSI certified (impact resistant) goggles when sharpening small bits! To minimize the risk of breaking bits, burning them because of too much material take off, or creating negative relief on the small bit, the Small Chuck is designed to have a very small Material Take Off (MTO). It will operate only at the high end of the Material Take Off

(MTO) adjustment range.

MOTOR STALL DELAY:

This screen will appear on the display:

The Grind Sensitivity is a measure of how quickly the controller responds to the material take off during AUTO grinding. A lower number generally creates more turns, a higher number means fewer turns before the controller decides it has reached the proper material removal. This variable is set at a factory default of

25. When Darex CBN and Diamond wheels are used, the setting of 25 is appropriate and will not need to be changed.

FACTORY BIT COUNT:

“Motor Stall Delay is used to detect a prolonged period of the Gear Motor not turning, sensing a blocked or jammed condition. The available settings are 2, 3 or 4 seconds; the factory default is 3 seconds. If the unit detects a 3 seconds lapse and the chuck has not rotated at least a half turn, the unit will shut itself off and “Sharpening Interrupted” will appear.

The system will reset itself.

Gripping the follower “Knob”, gently pull back and rotate the “Cam Follower” assembly as far counterclockwise as possible.

Release the “Knob”.

This will secure the chuck in the sharpening fixture.

To remove the chuck, wait for the sharpening fixture to come to a complete stop. Simply rotate the “Cam

far clockwise as possible. NOTE: It is not necessary to pull back when rotating the “Cam Follower” assembly clockwise.

DRILL STICK OUT- FINAL GRIND:

The Drill Stick Out - Final Grind amount on the Auto Sharpening system must be calibrated to produce the same Drill Stick Out - Final Grind amount as produced on your existing Manual

Before you begin sharpening with your Auto

system, take the time to calibrate Final Grind-

Drill Stick Out. This will help retain your cur-

rent point split depth calibration.

Verify Final Grind Drill Stick Out On Manual

System First:

1. Rotate material removal knob

to minimum take off setting.

2. Align drill in chuck. Once drill is set to length, aligned and securely captured in the chuck, remove from alignment port.

3. Using a height gauge, measure the amount of drill protruding from the end of the chuck to the tip of the drill. (Drill Stick Out - Before Grind)

4. Sharpen the drill until spark out has been achieved. Remove chuck from sharpening port. Without removing the drill, re-measure the amount of Drill Stick Out after grinding. Your Auto system must be adjusted to produce the same Final Grind - Drill Stick Out measurement as the manual system.

CALIBRATING DRILL STICK OUT - FINAL GRIND :

The swing cam on the chuck rests and rides on the Swing Bearing assembly. This bearing assembly is eccentric. The Auto Sharpening Fixture will arrive with this bearing positioned so that the drill will NOT make contact with the grinding wheel. By repositioning the bearing, the amount of material removed from the end of the drill will change, changing the Final Grind - Drill Stick Out amount.

1. Using a 3mm hex wrench, loosen the Swing Bearing Assembly, located on the back of the Pivot Base Casting.

2. To increase the amount of material removed from the end of the drill and reduce the Drill Stick Out amount, slightly rotate the bearing clockwise.

3. After repositioning the bearing, be sure to retighten the assembly bolt, securing the new position of the Swing Bearing Assembly.

4. Sharpen the drill and verify the amount of Final Grind - Drill Stick Out.

Repeat this procedure until the Final Grind Drill Stick Out amount measures the same as

ced with the Manual system.

Maintenance

This unit will display a “Maintenance Alert“ when maintenance is required. The screen will display:

Every 100 sharpenings this alert will appear as a reminder to perform the required routine maintenance listed below. Performing this maintenance will keep the auto sharpening fixture running properly and extend the life of the components. It will also help prevent excessive grit build up which will cause premature sharpening interruptions.

This is a good time to inspect the rest of the XT machine and perform any other necessary maintenance, see page 30.

For best performance and longevity of the Auto Sharpener we highly recommend the use of a dust extraction system. For more information contact DAREX @ 800-547-0222.

Once maintenance has been completed, using the “Arrow up” “Arrow down” buttons, highlight “Yes”.

To select yes press the select button. This will clear the “Maintenance Alert” and you may resume sharpening.

1. Power off the machine, waiting to perform the maintenance only once the grinding wheel has come to a complete stop.

Disconnect the power from the machine using a lock out tag out procedure.

2. Vacuum any grit found on the machine. Pay special attention to the electronic controller, the Follower Cam Tube Assembly and Chuck Tube Liner.

NOTE: Do not use an air gun, as this can blow grit into the Controller/Display housing or the Follower Cam Tube Assembly on the s ing port.

3. Use a clean, dry cloth to wipe down the chuck bodies and the inside liner of the chuck port. After using a dry cloth to clean these, use the lubricated cloth, (gun cloth or similar) provided, to re-apply a very fine lubrication to these surfaces. (You can also use a clean cloth with a light spray of silicone. Avoid aggressive solvent based lubricants like WD-40.)

machine using a lock out tag out procedure. After removing the wheel from the

sharpener, saturate the wheel with any type of oil-less solvent, such as Automotive Brake Cleaner. It is helpful to use a soft bristle brush and lightly brush the saturated wheel, loosening the impacted grinding particles. Re-saturate the wheel to flush out any loosened debris. Do not use any type of dressing tool on these wheels. Damage to surface will occur and greatly shorten the wheel life.

NOTE:

discolor or burn, the wheel life may be exhausted and the wheel will need to be replaced.

CHUCK MAINTENANCE

The use of a dust extraction system during grinding will help reduce the amount of maintenance, however, the chuck assembly should be disassembled and cleaned periodically. See XT3000 instruction manual for detailed disassembly instructions.

GRIT TRAY

At the back of the XT-3000 machine, located underneath the grinding motor is the grit tray. Drill grindings will accumulate inside the grit tray. The grit tray has a magnetic liner to attract and hold these dust particles. Do not let the tray become more than 1/3 full. To remove tray, unscrew brass thumb screw. Remove tray and dump contents. Wipe excess dust from the tray with a rag.

Darex recommends the use of a dust extraction system when the Auto Attachment is in use.

Trouble Shooting

The unit stopped working and the screen displays “Sharpening Interrupted”:

• This message will appear if the user

presses the “Stop” button during sharpening. It will also appear if the controller detects a large load on the chuck turning motor. This is typically caused by dirt or grit accumulating on the Chuck Body, Chuck Tube Liner, or the Cam Follower Assembly. Turn the machine off and perform the standard maintenance procedures listed on pages 29 & 30. Restart the machine and see if it runs without interruption. If the controller continues to show this message, call Darex customer service for assistance.

The display does not come on when I plug the unit it:

• The auto controller receives its power

through the AC plugs in the rear of the unit. Make sure there is power to the outlet you are using.

• Make sure the wiring on the back of the

unit matches that of the user manual (power comes in to the controlle both pigtails are

firmly seated between the

r, and

controller and the XT unit).

• Try unplugging and re-plugging these

cords to ensure they are well seated.

• Finally, make sure the on/off switch on the

XT-3000 machine is powered on. The display will not come on until you power up the XT-3000. If unsuccessful, call Darex customer service for assistance @ 800547-0222.

• If the optical switch in the Sharpening

Fixture is faulty, call Darex customer service for assistance.

• Check the small cable coming from the

sharpening port to the Gear Motor.

• Finally, remove both covers on the Gear

Motor and Gear located on the Sharpening Fixture. Verify the Drive Gear is secured to the Gear Motor.

The unit powers up and runs the sharpening system, but the vacuum does not come on:

• The vacuum receptacle for the Auto sharp-

ening system is located on the back of the Controller/Display housing, see page 14. Make sure this connector is firmly seated.

• The connector is fused with two 8A time

delay fuses (1.6A on the 230V international model). Make sure these fuses are intact. If a fuse is found to be blown, then both fuses should be replaced with the appropriate capacity. You can find the part

numbers for these fuses listed on page 26. Note: U not re

sing fuses not supplied by DAREX is

commended and may cause damage to

the Controller/Display.

If the grind motor starts but the Auto Display is off:

• The internal relay may be defective. This

can be detected by checking for voltage at

the vacuum output receptacle with an

electrical meter.

The unit powers up, the display is on, but pushing the “Start” button to sharpen nothing happens:

• There is a cord that connects the sharpen-

ing port to the Auto Controller/Display, see page 12. Be sure that the 5 pin DIN connector on this cord is firmly seated into the connector on the Controller/Display, paying careful attention to cord/connector orientation. Important:

See information on page 67. Inspect the cable, coming from the controller to the sharpening port, for damage.
