Safety Instructions for DARE Grinders

CAUTION

For Your Own Safety Read Instructions Manual Before Operating Grinder.

USE WHEELS MARKED AT OR OVER RPM OF 3450.

REPLACE CRACKED WHEEL IMMEDIATELY. ALWAYS USE GUARDS AND EYESHIELDS. SECURELY TIGHTEN WHEEL SCREWS. USE ONLY WASHERS FURNISHED WITH THIS GRINDER.

Always disconnect grinder from the power supply while motor is being connected or reconnected.

INSTALLATION

Check grinder nameplate to make certain the rating is correct for the power supply, voltage and frequency.

Mount grinder on solid bench. It may be used without bolting down for light work. For heavy work it should be bolted down to the mounting surface. If mounted on pedestal, bolt grinder securely to pedestal and bolt pedestal to floor.

All attachment plugs and any receptacles shall be replaced with devices rated for the voltage for which the motor is reconnected.

After making connections, make sure they are secured and properly insulated.

When starting a grinder for the first time, or after installing a replacement wheel, it is most important that the operator stand aside for at least one minute.

This is the correct practice since grinding wheels can explode if they have received minor cracks from shipping.

OPERATION

Check that switch is in "OFF" position and that wheels rotate freely. Insert plug into receptacle and turn on switch. Grinder should come up to speed smoothly and without vibration.

MAINTENANCE

No maintenance, other than replacement of worn wheels, is needed. Wheels should be replaced when worn down to one-half the original width.

The ball bearings used are lubricated for life and do not require additional lubrication.

Wipe off and dispose of grinding dust to prevent accumulation.

Safety Instructions

A. GROUNDING INSTRUCTIONS

1. 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 equipment-grounding 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 3-pole receptacles that accept the tool's plug.

Repair or replace damaged or worn cord immediately.

2. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating less than 150 volts:

This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Figure A. The tool has a grounding plug that looks like the plug illustrated in Figure A. A temporary adapter, which looks like the adapter illustrated in Figures B and C, may be used (except in Canada) to connect this plug to a 2-pole receptacle as shown in Figure B, if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The greencolored rigid ear, lug, etc. extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box.

Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating between 150-250 volts, inclusive:

B. FOR ALL TOOLS

1. KEEP GUARDS IN PLACE and in working order.
REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning it on.
3. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
DON'T USE IN DANGEROUS ENVIRONMENT. Don't use power tools in damp or wet locations, or expose them to rain. Keep work area well lighted.
5. KEEP CHILDREN AND VISITORS AWAY. Remove starter keys and turn off master switches.
6. PADLOCK EQUIPMENT or work area when not in use.
DON'T FORCE TOOL. It will do the job better and safer at the rate for which it was designed.
8. USE RIGHT TOOL. Don't force tool or attachment to do a job it was not designed for.
9. WEAR PROPER APPAREL. No loose clothing, neckties, rings, bracelets, or other jewelry to get caught in moving parts. Nonslip footwear is recommended. Wear protective hair covering to contain long hair.
10. ALWAYS USE SAFETY GLASSES. Also use face or dust mask if cutting operation is dusty. Everyday eyeglasses only have impact resistance lenses; they are NOT safety glasses.
11. SECURE WORK. Use clamps or a vise to hold work when practical. It's safer than using your hand and it frees both hands to operate tool.
12. DON'T OVERREACH. Keep proper footing and balance at all times.
13. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.
14. DISCONNECT TOOLS before servicing; when changing accessories such as blades, bits, cutters, etc.
15. AVOID ACCIDENTAL STARTING. Make sure switch is in "OFF" position before plugging in.
16. USE RECOMMENDED ACCESSORIES. Consult the owner's manual for recommended accessories. The use of improper accessories may cause hazards.
17. NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is accidentally contacted.
18. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to assure that it will operate properly and perform in its intended function—check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.
19. NEVER LEAVE TOOL RUNNING UNATTENDED. Turn power off.

Endmill Sharpener Instructions

INSTALL THE SPINDLE

Attach compressed air of at least 90 psi to the sleeve housing. (It's best to have an air filter and water trap installed between the shop air and the air spindle.)

Thoroughly clean the spindle and the sleeve bore (with the air on) using a clean lint-free cloth and a cleaner that leaves no residue.

2. Remove the drawbar from the spindle and with the air on, carefully place the spindle into the sleeve.
Make sure the spindle is in its highest position by loosening the spindle lever knob and moving the spindle lever all the way to the left (Figure 2).

BEGIN WITH A STANDARD ENDMILL

With these instructions and a Darex Endmill Sharpener, you will find that getting "the feel" of good endmill sharpening is not difficult. At first, as with anything new, the steps will seem unfamiliar, even if you have had sharpening experience. But these instructions were designed to alleviate any apprehension you might have.

First of all, there are no hidden "tricks" you need to know before you can resharpen your endmills. Everything is revealed step-by-step in these instructions. If you start at the beginning and take your time, you will soon learn how to sharpen endmills with ease and precision.

The real key is patience. Since you will learn by doing and by making some mistakes, don't feel bad about them. Figure on an hour or so of practice to become comfortable with your Darex. IMPOR-TANT: Start with a two or four flute endmill of at least 3/8" in diameter. It's sometimes helpful to color the areas you will be grinding with a felt pen. This helps you see what you have ground.

SHARPENING THE PRIMARY ANGLE ON THE FLUTES

Page 5

Page 6

SHARPEN THE ENDS

Make sure the corner of the grinding wheel is sharp before sharpening the end. (See wheel dressing, page 7). The sharpener is set to automatically produce a 2 degree "fishtail" on the end.

Note: E-80 users should position the grinding wheel so its centerline height is approximately 1/4" above the center height of the spindle in its highest position.

5. SHARPEN SECONDARY ANGLE

Note: Only sharpen secondary when primary becomes too wide:
a. Loosen spindle knob and move spindle lever to the right so spindle is in its lowest position.
b. Use same procedure as for sharpening primary. Don't remove too much material. Leave about a 1/16" - 1/8" wide primary edge.
Gashing can be done free hand or if you own a Darex Drill Sharpener with a point splitter, you can use the point splitter to sharpen the gash. (It may not be possible to grind secondary angle on small 6 or 8 flute endmills.)

Page 7

CHANGING THE RELIEF ON THE FLUTES

Changing the relief of the primary and secondary angle is very simple. For more relief, instead of aligning the stylus in the middle of the outside edge of the wheel, position it to the right of the high point. The further to the right you go, the more relief you will get. To get less relief, simply lower the spindle height a small amount using the spindle lever. The lower the spindle is, the less relief you will get.

DRESSING THE WHEEL

If you have a diamond dresser attachment (Darex No. 9050) first remove the stylus fixture and the spindle fixture from the ways. Mount the dresser attachment to the ways so the handle swings parallel to the grinding wheel. (It should also be parallel with the wheel guard cover.) Feed the wheel into the dresser and swing the dresser across the face of the wheel.

If you do not have a Darex diamond dresser attachment, manually dress the wheel with a dressing stick.

RE-SETTING THE STYLUS HEIGHT

If the stylus is accidentally ground, its height will have to be re-set to .010" below the center of the spindle. This is easily accomplished using the gauge supplied with your machine. You will find it located in the collet storage area.

To set the stylus, mount the gauge in the spindle using a 3/8" collet. Position the stylus under the gauge. (Make sure the stylus fixture is in the "primary" position.) Loosen the stylus lock nut and adjust the stylus until the tip intersects the bottom of the flat area at the tip of the gauge, as shown.

If there is not enough adjustment, the stylus will have to be replaced. Order Darex Part No. 8152

Page 8

WHEEL BALANCER INSTRUCTIONS

The Darex endmill sharpeners are equipped with a device for balancing the grinding wheel. It is a washer than can be offset to counter-balance variations in the grinding wheel. Loosen the three wheel mounting screws and try positioning the washer in different positions until the machine runs smoothly. (Wheels purchased from Darex will have an arrow indicating the light side of the grinding wheel.)

Trouble Shooting Guide

PROBLEM	CAUSE	SOLUTION
Flutes don't cut.	1. Stylus not in proper position.	Use the cross feed knob to move edge of the wheel so it aligns with the center on the stylus.
	2. Stylus not at proper height.	Re-set the height of the stylus. (See setting stylus height, page 7.)
	3. Primary edge too wide.	Sharpen more off the secondary angle.
	4. Improper relief.	See changing relief, page 7.
Endmill won't plunge cut.	1. End needs to be re-gashed.	By hand, on a bench grinder.
	2. End primary too wide.	Grind more off secondary.
Spindle won't float.	1. Spindle and/or sleeve not clean.	Remove spindle and clean spindle and sleeve.
	2. Spindle sleeve holes plugged.	Remove sleeve from sleeve housing and clean out holes with small wire.
	3. Not enough air pressure	Increase PSI to 90 or above.
Index pin won't drop in index collar holes.	1. Spindle sleeve not in proper position.	Move sleeve in housing until you can drop pin into index collar.
Inconsistent results (not grinding the same amount off each flute.	Collet and/or spindle taper where collet seats is not clean.	Clean thoroughly with a clean lint-free cloth.

Only remove enough material to "touch-up" the endmill. A secondary angle is not necessary for ball endmills. Remove the air spindle fixtur and stylus and mount the balladger endmill adapter endmill attachment. The stylus is not required when sharpening a ball endmill. When using the E-3 SHARPENING A BALL ENDMILL on equipment other than a Darex Endmill Sharpener, position the wheel so its centerine is 1/2" above the centerine of the E42 spindle

2. PREPARE INDEXING COLLAR

Rotate spindle until you can push the pin into a hole marked with a number that corresponds to the number of flutes you will be sharpening (2 for 2 flutes, 3 for 3 flutes, etc.). Clean collet and spindle, place endmill into collet and collet into spindle. Rotate flute to horizontal position and tighten collet with collet lock knob.

1. SET RADIUS FIXTURE TO "O"

a. If the radius fixture is not set to zero, loosen the 2 cap screws and slide the fixture to the zero position as

shown. Then retighten the cap screws.
