Southbend SB1027 owner manual To test the X-axis power feed unit and table limit switch

For Machines Mfg. Since 8/09 P R E P A R A T I O N Model SB1027

14.Turn the spindle direction switch to the stop (middle) position to prevent the spindle from starting when you next use the ON button.

15.Make sure the emergency STOP button has been reset, press the ON button, then start spindle rotation.

16.Push the spindle brake lever—the spindle motor should turn OFF and the spindle should come to a stop from the pressure of the brake.

17.Position the coolant nozzle over the table, turn the coolant switch on the control panel to the on (right) position to start the coolant pump, then open the valve at the base of the nozzle to begin the flow of coolant.

18.Check for leaks from the hose fittings and that the coolant is properly draining back into the reservoir through the screen on the base.

The mill comes with a power feed unit for X-axis table travel. Proper operation of the limit switch attached to the front middle of the table is critical for the safe use of this power feed unit.

If the power feed does not operate as expected during the following steps, disconnect it from power and contact our Tech Support at (360) 734-1540 for assistance.

To test the X-axis power feed unit and table limit switch:

1.Make sure all tools, cables, and other items are well clear of table movement as you follow these steps.

2.Refer to the Table Movement section, beginning on Page 27, to understand how the power feed, table locks, and limit switch function.

3.Loosen the table locks on the front of the table.

4.Plug the power feed power cord into a 110V power outlet.

Note: There are available 110V outlets on the right side of the electrical cabinet that can be used for the power feed or other 110V devices.

5.Make sure the power feed directional lever is in the neutral (middle) position, turn the speed dial counterclockwise to the lowest setting, then flip the power switch to the on (up) position.

6.Turn the directional lever to the left, slowly turn the speed dial clockwise to increase the speed, then confirm that the table is moving to the left.

7.Watch for the table limit stop to hit the limit switch and turn the power feed OFF, stopping the table movement.

8.Turn the directional lever through the neutral (middle) position and all the way to the right. The table should begin moving to the right.

9.Confirm that the table stops moving when the limit stop presses against the limit switch plunger.

10.Move the directional lever to the neutral (middle) position and flip the power switch to the off (down) position.

Congratulations! The Test Run of the mill is complete. Continue onto the next page to perform the Spindle Break-Inand Inspections & Adjustments procedures.
