9. Chucks and Chuck Mounting
When fitting chucks or faceplates, first ensure that spindle and chuck tapers are
scrupulously clean and that all cams lock in the correct positions, see Fig1. It may be
necessary when mounting a new chuck to re-set the cam lock studs (A). To do this,
remove the cap-head 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.
Now mount the chuck or faceplate on the spindle nose and tighten the six 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 re-adjust the stud as indicated in the illustration. Fit and tighten the locking
screw (B) at each stud before remounting the chuck for work. A reference mark should be
made on each correctly fitted chuck or faceplate to coincide with the reference mark
scribed in the spindle nose.
This will assist subsequent remounting. Do Not Interchange Chucks or faceplates
between lathes without checking for correct cam locking.
