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 bearings (each end
bracket) and once or twice during the day if used continuously. It will be necessary
to remove the gear train cover in order to oil the left hand bearing.
Inject a few drops also to the compound slide oilway, located on the slides’ 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.
Components should be dry, and all machined surfaces should be lightly oiled.
Always remove cutting tools, and store in a safe place.
MOTOR BRUSHES
The Motor brushes may be changed by
unscrewing the caps, visible at the front and rear
of the machine, beneath the Headstock, as
shown in Fig. 12
SETTINGS AND ADJUSTMENTS
Occasionally, it may be necessary to readjust various components in order to
maintain optimum performance. The adjustments that may be performed are as
follows:
A. CROSS-SLIDE ADJUSTMENTS
The cross-slide is mounted on a dovetail slide, as shown in fig. 13. Between the
sloping surfaces on one side of the dovetail, a ‘jib strip’ is inserted, which may be
tightened against the dovetail under the influence of three adjuster, or ’jib’ screws,
mounted along its’ length.
The jib screws are to be found on the right hand side of the slide, directly beneath
the compound slide handle. In time, wear will occur on the mating surfaces resulting
in a ‘sloppiness’ of action.
