Mark the surface of the work at the point where the cut is to end, i.e. the shoulder, using a scriber
or similar means, and move the saddle so that the cutting tool is directly opposite the mark, then
wind in the cross-slide so that the tool touches the surface of the work.
Whilst carrying out these manovres, rotate the chuck by hand to ensure that nothing will come
into contact with if when turning takes place, i.e. there is adequate clearance between the saddle ,
cross-slide, tool post or cutting tool, and the chuck.
When satisfied retract the cutting tool and wind the saddle away from the headstock, then 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
tool is a short distance from the right hand
edge of the work. Wind in the cross-slide
again one full 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 alight the marks. This is to take into.
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”(0.25mm) as your
depth of cut.
The setup is now complete to begin your cutting operation, but before starting, check the position
of the Clutch for changing the manual & auto feeding set to left ( a hand).
Switch the machine ON as described under ‘Starting Procedure’ and slowly feed the cutting tool
into the work using the manual feed handle. Proceed until you reach the previously marked line
on the work, then retract the tool one or two complete turns on the Cross-slide feed handle.
Wind the saddle back to the beginning then wind the tool the same number of turns “in”, plus the
depth of desired cut, and proceed to cut once more.
NOTE: this describes the procedure for general, rough cutting. For other types of cuts-finishing,
cutting shoulders etc., you should consult a suitable handbook.
IMPORTANT: Your left hand should always be free in order to hit the emergency stop
should it become necessary.
MAINTENANCE
For maximum performance, it is essential that the lathe is properly maintained.
BEFORE USE
Always inspect before use. Any damage should be repaired and maladjustments rectified.
Damage to machined surfaces should be repaired with an oil stone. Test by hand to ensure
smooth operation of all parts before use.
Inject a few drops of oil to the oilways at both leadscrew bearing (each end bracket once outwice
during the day if used continuously.
Inject a few drops also to the compound slide oil way, located on the slide top surface, between
the two hex socket head screws.
AFTER USE
Remove all swarf from the machine and thoroughly clean all surfaces. If coolant has been used,
ensure it has completely drained from the tray.
