Figure 5
This setting details a unit with a HCU,
reference to the HCU should be ignored
when setting the standard tool.
●Set the gap between the (1) and (2) to equal
the depth of drilling required PLUS the
distance the bit is above the work piece, by
sliding (3).
●Lock in position with (4) to the recommended
torque.
●Position the HCU in (3).
●Set the gap between (6) and (7) to a distance
as required above the work piece.
●Unscrew (8) away from the HCU to adjust the
resistance within the HCU to the minimum.
●Fully open the Figure 3 (13).
●Close Figure 3 (11).
●Connect the air supply and press Figure 3
(6).
●Adjust Figure 3 (11/13) to give required
advance, retract feeds for the operator.
● Use Figure 5 (1) for the nal depth
adjustment.
●Lock using Figure 5 (9).
●Carry out a set of trial drillings to determine
the ideal advance and HCU settings using
Figure 3 (11).
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 nished thread form, adjust as necessary
Figure 3 (11/13) and repeat until information
in NOTES 1 and 2 are satised.
