12. chUcks and chUcks 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 Fig. 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 Face Plates Between Lathes Without Checking
For Correct Cam Locking.
