4.0 Specifications

The JET Model J-1230R is a powerf ul and versatile radial arm dri ll pre ss. T he dri ll head is m ounted o n a n arm and can slide along the arm to position the spindle over the work piece. The arm itself c an be rotated on its support column to allow centering the spindle over the work piece.

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

The power train gears and spline shaft are made of high quality heat-treated and ground nickel chrome steel, offering greater strength and smoothness to high-torque loads. The spindle is of case hardened steel and supported by dual row taper roller and thrust ball bearings at the nose, with thrust and axial bearings at the top. The frame is made of Meehanite® and high-tensile strength cast iron.

A precision machined box table allows convenient posit ioning and clamping of smaller work pieces. The box table can be removed from the base to allow larger workpieces to be clamped on the base itself. Both table and base have multiple T-slots for clamping set-ups.

All lifti ng equipment must

be rated appropriately to safely sustain t he weight of the drill press. Do not allow anyone near or beneat h the machine while it is being moved.

4. Lift the machine and position it over the anchor bolts in an area with good lighting, and a level and well-supported floor.

5. Place the leveling pads beneath the level adjusting bolts. Place a level (its tolerance should be within 0.02mm/m) on the box table and level the machine.

6. The drill press MUST be anchored to the floor. Use the layout diagram in Section 6.1 as a guide, and mount the nuts to the ground bolts.

Failure to anchor the

machine properly, according to the diagrams, could result in the machine tipping over and consequent damage to the machine and possible injury to the machine operator and bystanders.

7. Connect the electrical service branch to the machine according to the instructions which follow in section 6.4 Electrical Connections. This work should be done only by a qualified and licensed electrician who is familiar with machine service and national and local codes.

6.4 Electrical Connections

Electrical set-up should be

performed only by a licensed electrician who is familiar with national and local electrical codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

Model J-1230R radial drills are tested before shipping, for all functions and circuits under electrical power specified for the machine and motors. The only hook-up requirement should be for correct connection to an appropriate cutout on an appropriate service branch.

Where the following instructions do not agree with local electrical codes and procedures, the applicable codes and procedures should be followed, exclusively.

Wiring diagram

A wiring diagram for the drill pre ss is found inside the door of the electrical cabinet. It is also shown at the back of this manual. 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.

Electrical branch service

The machine is wired for either a 230V or 460V 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.

It is recommended that the 230 volt Drill Press be connected to a dedicated 25 amp circuit with a 25 amp circuit breaker or time delay fuse. Connect the 460 volt drill press to a dedicated 15 amp circuit with 15 amp circuit breaker or time delay fuse.

Connecting branch to drill pr ess

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 switch (See Figure 10) to the ON position.

Make sure there is coola nt

in the flood coolant system before operating the pump.

6. Observe the rotation through the glass atop the pump. The shaft should be rotating in the direction of the arrow cast into the pump assembly. If the shaft is rotating the wrong direction, the power leads need to be switched. Correct as follows:

7. Disconnect power to t he machine by turning it off at the cutout box.

8. Reverse any two of the power lead connections.

9. Repeat steps 4, 5, and 6, above, and you should observe the pump shaft turning in the proper direction. The electrical service to the machine is now complete.

A service disconnect is rec ommended. 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 from the branch circuit when working with tooling on the machine.
