Thread tapping with option „ZAP“ via remote control
ZAP = Z-axis pneumatic spindle feed system
NOTE
The following instructions apply only if ZAP equipment is installed.
1. Lock hand lever out (only megatap II).
2. Set retracting force with lever of the spring balance system:
The balance system lever should be set so that the spindle returns to the back
position by itself. The return force should be kept to a minimum for best tap life.
3. Switch on the machine.
4. Set spindle feed velocity of the pressure cylinder.
-
Select in Motor Setup “ START Fz” (Start after Fz-force is reached or start
manually with push button).
-
Press foot switch until the spindle reaches the material. The spindle starts to
work if the preset Fz force is reached (the feeding speed can be set with an
adjusting srew on the valve).
5. Insert desired tool.
6. If needed, set retracting force with lever of the spring balance system.
7. Mount workpiece
NOTE
Leave a distance of at least 5 mm between workpiece and tool.
8. Enter the appropriate process parameters in the operating menu:
- thread
depth
- spindle
speed
- torque limit (max. Mz).
WARNING!
The selected limiting torque must always be less than the fracture torque of the tool!
If you fail to observe this rule, the tool my break when reaching the bottom of the
ground hole! Small particles can turn into dangerous bullets!
9. Select in Start Setup the operation mode and set the desired parameter.
Wear eye protection.
