General specifications

The Wilton Model 1230 is a powerful and versatile radial arm drill press. The drill head is mounted on an arm and can move along the arm to position the spindle over the work piece. The arm, itself, can be rotated on its support column to allow centering the spindle over the work piece.

Drilling can be performed manually or with power assistance. In addition, parameters of RPM, power feed rate and drilling depth can be pre-set by the operator, using controls conveniently positioned on the drill head, to allow any hole to be drilled using power feed.

A precision machined box table is delivered with the Model 1230 to allow convenient positioning and clamping of smaller work pieces. The box table may be removed from the base to allow larger workpieces to be positioned and clamped on the precision machined base, itself.

Machinery general safety warnings

1. Always wear protective eye wear when operating machinery . Eye wear shall be impact resistant, protective safety glasses with side shields which comply with ANSI Z87.1 specifications. Use of eye wear which does not comply with ANSI Z87.1 specifications could result in severe injury from breakage of eye protection.

2. Wear proper apparel. No loose clothing or jewelry which can get caught in moving parts. Rubber soled footwear is recommended for best footing.

3. Do not overreach. Failure to maintain proper working position can cause you to fall into the machine or cause your clothing to get caught — pulling you into the machine.

4. Keep guards in place and in proper working order. Do not operate the machine with guards removed.

5. Avoid dangerous working environments. Do not use stationary machine tools in wet or damp locations. Keep work areas clean and well lit. Special electrics should be used when working on flammable materials.

6. Avoid accidental starts by being sure the start switch is “OFF” before plugging in the machine.

7. Never leave the machine running while unattended. Machine shall be shut off whenever it is not in operation.

8. Disconnect electrical power before servicing. Whenever changing accessories or general maintenance is done on the machine, electrical power to the machine must be disconnected before work is done.

9. Maintain all machine tools with care. Follow all maintenance instructions for lubricating and the changing of accessories. No attempt shall be made to modify or have makeshift repairs done to the machine. This not only voids the warranty but also renders the machine unsafe.

10. Machinery must be anchored to the floor.

1 1. Secure work. Use clamps or a vise to hold work, when practical. It is safer than using your hands and it frees both hands to operate the machine.

12. Never brush away chips while the machine

is in operation.

13. Keep work area clean. Cluttered areas

invite accidents.

Caution: for circuits which are far away from the electrical service box, the wire size must be increased in order to deliver ample voltage to the motor. To minimize power losses and to prevent motor overheating and burnout, the use of wire sizes for branch circuits or electrical extension cords according to the following table is recommended:

Safety instructions on drill presses

1. All work shall be secured using either clamps or a vise to the drill press table. It is unsafe to use your hands to hold any workpiece being drilled.

2. Drill press head and table shall be securely locked to the column before operating the drill press. This must always be checked prior to starting the machine.

3. Always use the correct tooling. Tooling shall always be maintained and properly sharpened. All tooling must be run at the proper speeds and feeds as they apply to the job. Use only recommended accessories and follow those manufacturers instruc-

tions pertaining to them. T ooling shall not be forced in to any workpiece but fed according to the proper specifications. Failure to follow these instructions will not only ruin the tooling as well as the machine, but can cause serious injury.

4. Never brush away any chips while the machine is in operation. All clean up should be done when the machine is stopped.

5. Keep hands in sight. Do not put hands or

fingers around, on, or below any rotating cutting tools. Leather safety gloves should be used when handling any sharp objects or cutting tools. See Figure A.

6. Always wear protective eye wear when operating, servicing or adjusting machinery . Eyewear shall be impact resistant, protective safety glasses with side shields complying with ANSI Z87.1 specifications. Use of eye wear which does not comply with ANSI Z87.1 specifications could result in severe injury from breakage of eye protection. See

figure B.

7. When drilling in material which causes dust, a dust mask shall be work. See Figure C.

8. Avoid contact with coolant, especially guarding the eyes.

9. Non-slip footwear and safety shoes are recommended. See figure D.

12. Wear ear protectors (plugs or muffs) during extended periods of operation. See figure E.

Operating Instructions

Clamping workpieces to the machine

Both the box table and the base surface are slotted to accept a suitably sized T-slot clamp. Before begining any work on the drill press, anchor the work piece, and the box table, too, if used, to be certain the workpiece and/or box table will not move when the drill, tap or boring tool enters the workpiece.

Caution

Failure to properly anchor the workpiece and box table could result in damage to the machine, damage to the workpiece, and worse -severe injury and possibly operator. clamping the materials using a T-slot system setup.

Inserting tooling

The Model 1230 uses a #4 Morse taper in the spindle to secure tooling. Any drill, milling cutter, or tool holder with a #4MT can be inserted into the quill.

Caution

The first step in removing or inserting any tooling is to be absolutely certain the machine cannot be accidentally started during the insertion or removal operation. The only way to be certain of this fact is to disconnect power to the machine using the service box cut-out switch. The service box (typically the one holding the fuses or circuit breakers will have been installed by the electrician who connected the machine to its service branch) should have a cut-out switch or lever on the outside of the box. Put the switch or lever in the OFF position before inserting or removing tooling.

To insert tooling:

1. Observe the caution, above, and be certain all power to the machine has been disconnected.

2. Be certain the spindle is clean, free from oil, and ready to accept the shank of any tooling.

3. Check the shank of the tooling to be certain the tooling is free from dirt, nicks or burrs. If any nicks or burrs are discovered, file and/or stone the shank until the shank is smooth.

4. Be certain the quill is in the full UP position.

5. Slide the shank of the tooling into the spindle until it seats.

6. Use a soft-faced mallet (such as lead, plastic, brass, etc.) to give the tooling a sharp tap on its tip. This will secure the tooling firmly in the taper.

7. Re-establish power to the machine and the drill is ready to use.

To remove tooling:

1. Observe the caution above and be certain all electrical power to the drill press has been cut off.

2. Place a wood block under the tooling in the spindle to prevent it from being damaged, should it fall out of the quill during the removal process.

3. Lower the quill by using the feed levers until the tool removal window is exposed.

4. Using a suitable tapered drift, insert the drift in the removal window, above the tip of the tooling shank.

5. Using leather gloves to prevent cuts from the tooling, hold the tooling with you hand to prevent it from falling from the quill.

6. With your free hand, using a hammer, tap the tapered drift and the tooling will loosen from the taper and can be removed. The spindle is now ready for the insertion of other tooling with a #4 MT .

Positioning the tooling over the

workpiece.

After the workpiece has been clamped to the base or table you can position the tooling over the workpiece by doing any or all of the following:

1. Adjusting the height of the arm on the support column.

2. Moving the drill head along the arm.

3. Rotating the column upon which the arm and head are attached.

Unlocking the arm and column

mechanisms

A motorized locking system is used to lock the head to the arm, the arm to the column, and the column to the base.

The lock and unlock buttons which control the locks are located on the right-hand side of the drill head. When you push UNLOCK, all of the locks are unlocked. When you push LOCK, all of the locks are locked.

Caution

Always be certain the locks are engaged before using the drill press. Pull on the arm handle and try to rotate the head locating wheel before pushing the spindle ON button. Failure to have all locks locked may result in damage to tooling, damage to the work piece, and possible injury to the operator.

Raising and lowering the radial arm

1. Power to the drill press must be ON -- then release the machine locks by pushing the UNLOCK push button.

2. Use the control lever -- push it upward or downward as required -- (see Fig. 3) to raise or lower the arm to the required height. See also,

control lever

3. When the arm is at the required height and if no other adjustments to spindle location are required, push the LOCK push button to re-lock all machine locks.

Using the

To move the drill head along the arm

1. Power to the drill press must be ON -- then release the machine locks by pushing the UNLOCK push button.

2. Using the wheel in the center of the drill head, turn the wheel to move the drill head along the arm. (See Fig. 1.)

3. When the drill head is at the desired position on the arm and if no other adjustments to spindle location are required, push the LOCK push button to re-lock all machine locks.

CAUTION

NEVER swing the drill press arm using the support column unless you are absolutely certain the drill press base is firmly attached to the shop floor. You can tell if the base is bolted to the floor by checking the mounting pads at the four corners of the base. There should be a securing bolt through each mounting pad.

If the arm is moved off of its position directly above the base and the base is not bolted to the floor, THE DRILL MAY TIP OVER AND CAUSE SERIOUS INJURY OR DEA TH TO THE DRILL PRESS OPERA TOR (YOU!!) and will certainly result in serious damage to the drill press, itself. Don't take chances. Always look for bolts at the mounting pads before swinging the drill press arm.

on LOW or HI speed. There is a chart on the front of the drill head which shows you the spindle speeds available and the gear change lever and motor switch values required to select each speed. See Fig. 1.

On the gear change table you will also find the recommended drill sizes for the various speeds which are selectable. THESE RECOMMENDA TIONS ARE ONL Y APPROXIMA TE. With the wide variety of drill types and coatings available, the variety of cutting fluids which might be used, and the even wider variety of work piece materials which you might be machining -- you need to consult with your tooling, coolant and/or work piece suppliers to determine the best spindle speed to use for any specific drilling operation.

Moving the arm on the support column

1. Power to the drill press must be ON -- then release the machine locks by pushing the UNLOCK push button.

2. Use the handle at the end of the arm (see Fig. 1) to move the column (and, therefore, to swing the arm) as necessary to the required spindle position.

3. When the spindle is positioned correctly and no other adjustments are quired, push the LOCK push button to re-lock all machine locks.

Setting spindle speed

Spindle speeds are established using the gear change levers on the upper right-hand side of the drill head. (See Fig. 1.) The shorter of the two levers operates a two-speed mechanism which puts the gearbox in either high gear or low gear. There is a "HI/LOW" readout on the upper left hand side of the drill head which tells you which speed range is selected.

The longer gear change lever operates a three speed gearbox mechanism. The lowest gear and spindle speed is selected by pushing the lever away from you -- that is, by rotating the change shaft counterclockwise. The highest gear and spindle speed is selected by pulling the lever toward you -rotating the shaft clockwise. There is a detent in the middle of the lever travel to tell you when the lever is in the intermediate gear position.

This gearbox set-up gives you a total of six spindle speeds which may be selected. The twospeed spindle drive motor, therefore, increases the number of available spindle speeds to 12. The specific spindle speed selected clearly depends on the position of the

Caution

Do not try to change gears while the spindle is turning. This may cause serious damage to the spindle drive system.

Allow the spindle to come to a complete stop before attempting to change gears. If the gear change lever you want to move does not slip easily into the new position you require, jog the motor for a second using the control lever. Then allow the spindle to come to a stop again before attempting to change gears, again. Repeat this jogging process, as necessary , until the gears match up properly for changing.

Setting feed rate and depth of cut

The Model 1230 has limit switches on the quill which cuts off electric power to the drive motor when the quill has reached either the upper or lower limit of its travel. This system is designed to prevent gearbox damage if the power feed mechanism is engaged -damage which would occur if the quill were to bottom out against the upper or lower limit of quill travel. In the event of failure of either limit switch there is also a safety clutch mechanism which will slip when the limits of travel are reached.

However, while you are able to use virtually the full travel of the quill for drilling or other operations, the drill press operator typically sets both the rate of feed -- travel-per-revolution of the spindle -- and the depth of cut -- that is, the total distance the quill moves to make the required depth of cut.

These two operations are described, here:

Setting feed rate

The feed rate is set using the knob and dial on the front of the drill head. See Fig. 1. The knob on the dial can be rotated to select any of three different

feed rates, plus a neutral position where the power feed does not operate on the quill.

It is recommended that when doing operations which do not require power feed that the dial be set to the neutral position. This minimizes any wear on the power feed mechanism.

The feed rate selected is indicated by a pair of rivet heads on the edge of the rate setting dial. These values are indicated on the far outer edge of the readout.

Clearly , whenever the indicator rivets are at an "N" position, no feed or "neutral" has been selected.

Any of the three feed rates are available for selection using any of the spindle speeds available. There will be a recommended feed rate for any drilling or boring operation, and this rate must be determined by consulting appropriate machining handbooks or by consulting with your tooling, coolant and work piece suppliers.

Setting depth of cut using the power

feed system

There is a mechanism for engaging the power feed and there is also a mechanism (a "trip mechanism) which can be set to disengage the power feed when a pre-set depth has been reached.

The feed levers can be pulled outward -- or

pushed inward -- on pivots which are in the feed lever hub. When the feed levers are pushed toward the drill head, the power feed mechanism is disengaged. When the feed levers are pulled outward, the power feed system is engaged. In the power feed position (outward) the quill and spindle will be driven EITHER until they reach the limit of travel and the limit switches cut off power -- OR until the trip mechanism disengages the power feed, automatically -- OR until the drill press operator pushes the feed levers into the disengaged position.

To set the depth of cut

1. Unlock lever A -- See Fig. 2.

2. Use the feed levers to lower the drill until it touches the work piece.

3. Rotate the dial D until the rivet on the dial -- C -- is at the feed depth required on the scale on graduated dial B.

4. Lock lever A.

5. Pull the feed levers out to engage the power feed clutch.

Note: Because the ring for Dial B makes one rotation before contacting the mechanical trip dog, you are limited to 4 inches (100mm) of travel during any power feed operation. If you need to make deeper holes you will need to do the machining in steps.

Figure 2: Power feed controls

Spindle direction and power feed

The spindle can be driven clockwise or counterclockwise. The direction of rotation is controlled by the control lever on the left hand side of the drill head. See Fig. 1.

Clockwise or "forward" rotation is the direction of rotation for right-hand tooling -- which is the vast majority of tooling used in machine operations. However, if you use left-hand tooling for any operations, the spindle direction can be set to counterclockwise or "reverse."

The power feed direction is determined by the spindle direction. When the spindle is set to its most common direction -- clockwise or forward -- the quill and spindle are driven downward. When the spindle direction is set to counterclockwise or reverse direction, the quill and spindle are driven upward.

Hand feed -- roughing operations

When the feed levers are pushed toward the drill head the power feed mechanism is disengaged. In this position, the feed levers can be used to move the quill and spindle and perform manual drilling or other machining operations.

the tooling is installed, you can restablish power to the machine by turning the cut-out panel back ON. This will reestablish power to the machine control system and will allow you to use the motor which raises and lowers the arm to position the tooling over the work piece. Raising and lowering of the arm is controlled by the control stick -- see Fig. 3 and read page 7,

Raising and lowering the radial arm

Power ON light

When the cutout box power is ON, the POWER

light on the upper left hand side of the drill head (Fig.

1) will be lit. In this mode, power to the coolant pump and to the spindle drive motor is controlled by the switches on the control console.

Flood coolant control

The flood coolant system provided with the drill press is turned on by turning the switch to the ON position. Power OFF to the coolant pump is achieved by turning the switch counterclockwise to its OFF position. (If coolant does not flow, check the pump rotation by observing the pump shaft. It should be rotating in the direction of the arrow on the pump casting. If it is not rotating in the correct direction, see

Electrical,

for more information.)

Fine hand feed using the power feed

system

The fine feed control wheel is located on the underside of the right-hand side of the drill head. See Fig. 1. The fine feed control is used as follows:

1. Set the feed rate dial to N -- neutral.

2. Pull the feed levers out so the power feed clutch is engaged.

3. Turn the drill press POWER switch ON and set the control lever so the spindle is turning in the correct direction for the operation you are performing.

4. Turn the fine feed control wheel by hand. The quill and spindle will move downward or upward (depending upon which way you turn the wheel and the direction the spindle is turning) until you stop turning the control wheel.

Power ON and power OFF

If your Model 1230 was connected to its service branch correctly , there will be a service disconnect with an external power cutoff lever or switch which disconnects the drill press from the service branch. This is your ultimate protection against accidental machine start-up when clamping work pieces to the machine and/or inserting or removing tooling. Always be certain you have turned off power at this disconnect before doing these operations.

Once your workpiece is clamped securely and

Spindle motor controls

The power to the spindle motor controlled as

follows:

1. The cutout box control lever must be in the ON position so power is being fed to the drill press.

2. The two speed spindle drive motor switch must be in either HI or LOW position.

3. The control ON/OFF switch must be pushed ON.

4. The arm/spindle control lever must be pulled forward (clockwise rotation) or backward (counterclockwise rotation.) See page 1 1.

Turning spindle drive motor power OFF

T o turn power OFF on the spindle drive motor do

one of the following:

1. Put the two speed motor switch in OFF position, OR...

2. Push the Control ON/OFF switch off, OR...

3. Put the arm/spindle control lever in its middle (neutral) position, OR...

4. Push the large, red emergency off STOP switch, OR...

5. When servicing the tooling or other machine components, put the service disconnect lever in OFF position.

Once the STOP switch has been pushed (4., above) none of the other switches on the panel can be used to control power to the spindle drive motor or coolant pump until the STOP switch has been re-set.

Using the control lever,

Resetting the STOP switch

1. Turn the switch in the direction of the arrow on the red button -- clockwise. The switch is reset and the other spindle motor controls can be used.

Using the load ammeter

An ammeter on the control console is used to monitor the load on the spindle drive motor. It is connected into one of the three power lines which supply the main drive motor.

When the drive motor is ON and up to speed, and there is no tooling being used to drill, tap or bore a hole, the ammeter should read approximately 2.5 amps. If it is above this value there is a problem internally (such as lack of lubrication in the gearboxes, bad bearings, etc.) which means you should turn off the machine and determine the cause of the excessive free-running load.

Monitor the the ammeter during machining operations. The ammeter should stay below 9 amps or current draw during machining. Y ou should adjust your spindle speed, feed rate and coolant use to maintain the full load current draw below the 9 amp value.

If you exceed 9 amps current draw a thermal limiter switch in the electrical control panel will trip. If this occurs, a licensed electrician should be used to locate and re-set the thermal limiter switch.

Using the control lever

The four-position control lever is located on the left hand side of the drill head console. See Figs. 1 and 3.

The control lever can move up or down, backward or forward, or can be left in its most central, OFF or control power.

arm up or down when positioning the tooling over the work piece. This ability to control the height of the arm is available when:

1. The main power to the machine is ON at its branch service panel.

2. The emergency STOP switch is set to its ON mode.

3. The Control ON/OFF switch (lower left hand side of the face of the drill head, see Fig. 1) pushed ON.

4. The column and arm UNLOCK button (right hand side of the drill head -- see Fig. 1) is pressed to unlock the machine locks. See page 6.

it is released. It stays in the position in which you have placed it. This means unless you return it to neutral, the arm will keep raising or lowering until it contacts one of its limit switches.

Tapping operations

When performing tapping operations :

1. Determine the most efficient tapping speed (spindle speed) by consulting appropriate machinist's tables, your tap supplier, coolant supplier and/or work piece supplier.

2. Be certain the power feed dial is in N or neutral position. See

3. Turn the spindle motor ON. Also, turn on the coolant pump if coolant is being used.

4. Move the control lever to FORWARD.

5. Use the feed levers to move the tap into its pilot hole until the tap makes its initial thread cut and is engaged in the workpiece.

6. Allow the tap to "self feed" into the pilot hole until it has completed its tapping operation.

7. Move the control lever into its center/neutral position until the spindle has come to a complete stop.

8. Move the control lever into its reverse direction so the tap unscrews itself from the hole it has just threaded.

Electrical branch service

The machine is wired for either a 230 or 460 3phase service branch. The cable supplying the drill press will be tagged with the voltage at which the machine was tested and corresponding to the customer's order.

If the tag has been lost, it will be necessary for you to open the electrical cabinet on the rear of the drill press and examine the connections on the transformer found inside the box. The transformer can be connected to either a 230 or 460 volt source and its taps are labeled for voltage. By locating the source tap on the transformer you will be able to determine the branch voltage required.

A service disconnect is recommended. The use of fuses or circuit breakers for each of the voltage supply wires is required. Use fuses or circuit breakers which are appropriate to the voltage for the motor system delivered.

A positive cut-out/lock-out lever or rocker switch should be located on the outside of the service disconnect to allow the machine operator to disconnect the machine from the branch circuit when working with tooling on the machine.

Wiring diagram

A wiring diagram for the drill press is found on the facing page. This diagram is for reference by your licensed installing or servicing electrician. In addition to using a licensed electrician for connection to the drill press service branch, the servicing of components and circuits inside the control box should be serviced only by a qualified electrician. This includes fuse replacement, if required. If any of these fuses, upon replacement, should continue to fail at short service intervals, the electrician should be asked to check all machine components for excessive loads, short circuits or other failures.

To connect the branch to the drill press

1. Disconnect the service branch to the machine by moving the lever or rocker switch on the cutout box to OFF . 2 Connect the green wire (or green with white trace) to the branch ground.

3. Connect the remaining three wires in the cable (labeled R,S and T) to the three power lines in the branch.

4. Turn the power to the machine ON at the cutout box.

5. Turn the coolant pump power switch (See Fig. 1)
