Tapping Mode

 

Coolant System

 

 

 

 

 

 

When in tapping mode, the spindle direction can immediately alternate between forward and reverse by pressing any of the three buttons at the end of the downfeed handles. This feature is criti- cal to back the tap out of a hole before it bottoms out and snaps off, as well as clearing away waste chips during the tapping process.

Pilot holes must be drilled prior to beginning any tapping operation.

To use tapping mode:

1. DISCONNECT MACHINE FROM POWER!

2.Determine the maximum tapping depth with- out bottoming-out the tap, and adjust the depth stop accordingly.

3. Clamp the workpiece to the table.

4. Put on safety glasses and a face shield. Select tapping mode, and turn the spindle rotation switch counter-clockwise.

5. Install the tap, and apply tapping fluid to the contact point of the tap and workpiece.

6. Connect the machine to power.

7. Select "tapping" mode with the drilling/tap- ping switch

8. Select the appropriate spindle speed. Speeds vary according to the material, bit, and proce- dure. There are several online resources to choose from for calculating spindle speed

9.Press the spindle start button.

10. Begin threading. Without disengaging the tap from the threads, frequently alternate spindle rotation by pressing any end button to reverse spindle and eject chips from the hole. Frequently removing chips will prevent galling and tap breakage.

This machine comes with a coolant system for use in drilling and tapping operations. This feature promotes precision cutting and tool longevity.

To operate the coolant system:

1. ensure there is a sufficient amount of clean coolant in the reservoir (refer to Page 20 for detailed instructions).

2. Aim the coolant nozzle at the contact area of the workpiece and the work tool.

3. Turn the coolant pump switch on the control panel to the ON position.

4. Regulate the coolant flow to the contact area using the coolant ball valve shown in Figure 25.
