Whilst carrying out these manoeuvres, rotate the chuck by hand to ensure
that nothing will come into contact with it when turning takes place, i.e. there
is adequate clearance between the saddle, cross-slide, tool post or cutting
tool, and the chuck.
It may be necessary to adjust the position of the compound slide or reposition
the work in the chuck to guarantee that there is adequate clearance.
When satisfied, retract the cutting tool
and wind the saddle away from the
headstock. Wind the cutting tool up
to the work, somewhere along the
length to be cut, whilst rotating the
work by hand using the chuck.
Continue to advance the cutting tool
slowly until it just touches the surface.
Record this position by zeroing the
scale on the cross-slide, i.e. turn the
moveable scale until the zero marks
coincide, (see diagram).
Once zeroed, retract the cross-slide
one complete turn, then move the
saddle until the tool is a short distance from the right hand edge of the work.
Wind in the cross-slide again one full turn until the zero marks again coincide.
IMPORTANT: If you go past the zero marks, back off again at least one half
of a turn, then slowly bring the marks back together.
Whenever you use the scale, as an indicator, to advance the cross-slide or
compound slide, ALWAYS use this procedure to align the marks. This is to take
into account backlash and other clearances in the gearing and slides etc.
Continue to turn the handle an amount equivalent to your desired depth of
cut.
NOTE:
We recommend that for rough cutting, you do not exceed 0.010” as
your depth of cut.
The setup is now complete to begin your cutting operation, but before
starting, check the position of:
• Auto feed lever. Ensure it is in the UP position for manual feed.
• Forward/Neutral/Reverse leadscrew lever. If Auto feed is not required,
set to Neutral’.
• HIGH/LOW lever. Select required speed range.
Switch the machine ON as described under ‘Starting Procedure’ and slowly
feed the cutting tool into the work using the Manual Feed Handle. Proceed
