Tapping
In general, speeds for tapping require low transmission mode with speeds lower than 150 RPM.
Important: Chamfer the holes before tapping. A tapping rate of eight times per
minute or less is recommended. All tapping must be done while in manual mode.
1. Set the down-fee
d rate to “0” using the down-feed handle.
2. Turn the selector switch on the electrical cabinet to tapping mode.
3. Lock the down-feed handles in position for manual down-feed with handle. The down-feed
must be locked to avoid accidentally changing to auto down-feed.
4. Release the unused depth stop by loosening handle.
5. Start the machine by pushing button.
6. Turn on the coolant selector switch.
7. Begin tapping. Use the down-feed handles to enter the tapping bit into the piece part.
Release hold of the handles. The bit will automatically reverse upon reaching the depth stop.
Micro-Feed Hand Wheel
The micro-feed handwheel allows for slow and accurate movement of the drilling tool. It also has
an anti-spin feature when the hand wheel will not be used. Pull downward on the knob to
disengage the micro-feed hand wheel during auto down-feed and non-use.
1. Adjust the rate of spindle down-
feed to “0” using feed rate handle.
2. Set the tool depth to a zero position by lowering the tip of the bit to the top of the piece part.
3. Push up on the micro-feed handle to engage the hand wheel.
4. Set the scale to zero by rotating the depth ring (P).
5. Lock the depth ring by tightening the thumbscrew (AL).
6. Turn the micro-feed hand wheel clockwise (cw) to lower the spindle.
NOTICE: This is a conventional drill, not a special purpose machine, therefore frequent
tapping jobs will wear the motor and gears.
Temperature of motor will be increased quickly
when tapping due to low motor RPM and frequently motor direction be changed. Therefore,
rapid and continuous tapping shall be avoided. Maximum of eight times per minutes of
tapping is recommended. The machine shall be stopped for cooling if the motor is too hot.
