hand tapping scale. (The tapping function has an extra
4mm movement when the crank handle is released, a
4mm pre-adjustment has been made on the scale.
Therefore, when "zeroing-in" the tapping scale, the 4mm
mark is the effective datum point. A minimum depth of
5mm can be tapped and a maximum of 40mm). Now that
you have the depth scale calibrated, you may use the meter
reading to set the Travel Limiter Stop.
SETTING THE TRAVEL LIMITER STOP
When at its lowest position, the travel limiter stop will not effect
the stroke of the slide. When tapping blind holes the travel limiter
stop must be used to avoid the tap bottoming. When tapping
through holes or when drilling, the limiter stop is not needed.
To properly set
1. With the tap mounted on the machine, place the machine
on the workpiece.
2. Using the depth meter, Carefully measure the furthest
depth that the tap is intended to go. With the tap
overhanging the edge of the workpiece, lower the slide to
the intended depth.
3. Loosen the lock nut then adjust the stop to just meet the
slide, retighten the lock nut.
4. When no longer needed, lower the stop to its lowest
position.
TAPPING OPERATION
NOTE: It is recommended to always use cutting oil on the tap to give longer tap life and better results.
The automatic coolant system only works for annular cutters. Taps must be lubricated manually.
1. Before tapping begins, there must be a proper sized hole. Make sure that the hole is the correct size for
the tap.
2. With the magnet switch still off, maneuver the tap and machine to ensure that the tap is perfectly aligned
with the hole. Actually insert the nose of the tap into the hole slightly to ensure perfect alignment, then
switch on the magnet.
