SETTING TAPPING OPERATION
Note 1: lt is important that the advance
rate of the tool is set to match the pitch
of the thread which is to be tapped.
An incorrect advance rate will result in
a deformed thread, this will be more
noticeable in plastics or light alloy
materials.
Note 2: The retract rate should be set to
withdraw the tap at a slightly faster rate
than it advanced, this will ensure a clean
withdrawal.
● Mount a tool, with the selected tap securely
retained in the chuck, above a test block to
carry out sample tapping operations.
● The end of the tap MUST be at least 14mm
(9/16in) above the test block, to allow for the
tapping head reversing engagement travel.
● Set the gap between Figure 5 (2) and (1) to
equal the tapping depth PLUS the distance
the tap is above the work piece.
● Adjust Figure 3 (11/13) to give the required
advance, retract feeds for the operation.
● Carry out a trial tapping operation and inspect
the finished thread form, adjust as necessary
Figure 3 (11/13) and repeat until information
in NOTES 1 and 2 are satisfied.
