6.5 LUBRICATION CHECKS
Before operating the machine make the following
important checks:
1. That the headstock is filled to level marked
on oil sight window with Shell Tellus Oil 27 ,
Mobil DTE Oil Light (DIN 51517-2 CL ISO VG
32 ) or equivalent.
2. That the gearbox is filled to level marked on
oil sight window with Shell Tellus Oil 27 ,
Mobil DTE Oil Light (DIN 51517-2 CL ISO VG
32 ) or equivalent.
3. That the carriage apron is filled to level
mark on oil sight window with Shell Tellus
Oil 33, Mobil DTE Oil Heavy Medium (DIN
51517-2 CL ISO VG 68) or equivalent.
4. In addition, apply an oil can to the points
shown on lubrication diagram which require
daily oiling. Use light machine oil or way
lubricant Shell Tonna 33, Mobil Vectra 2
(DIN 51502 CG ISO VG 68) or equivalent.
6.6 CHUCKS AND CHUCK MOUNTING
When mounting chucks or faceplate, first, ensure
that spindle and chuck tapers are thoroughly
cleaned and that all cams lock in the correct
positions, see figure. It may be necessary when
mounting a new chuck to reset the
camlock studs (A). To do this, remove the caphead
locking screws (B) and set each stud so that the
scribed ring (C) is flush with the rear face of the
chuck - with the slot lining up with the locking
screw hole (see Fig 10).
Now mount the chuck or faceplate on the spindle
nose and tighten the three cams in turn. When
fully tightened, the cam lock line on each cam
should be between the two V marks on the spindle
nose.
If any of the cams do not tighten fully within these
limit marks, remove the chuck or faceplate and
readjust the stud as indicated in the illustration. Fit
and tighten the locking screw (B) at each stud
before remounting the chuck for work.
This will assist subsequent remounting.
Note: Do not interchange chucks or faceplates
between lathes without checking for correct cam
locking beforehand.
Note: Take careful note of speed limitation when
using faceplate; the 300mm faceplate should not
be run at speeds greater than 770 RPM.
