Mounting Chuck or Faceplate

1.DISCONNECT LATHE FROM POWER!

2.Lay a chuck cradle or a protective layer of plywood under the chuck or faceplate and over the bedway to protect the precision ground surfaces from damage and to prevent fingers from being pinched.

3.Clean away debris and oily substances from the mating surfaces of the spindle and chuck or faceplate.

4.Position the chuck or faceplate in front of the spindle nose with the cam-lock studs aligned with the sockets, then carefully insert the chuck or faceplate onto the spindle (see

Figure 25).

5.Slowly tighten each cam-lock clockwise until you feel it engage the cam-lock stud, then continue to turn the cam-lock until you cannot turn it any further.

As you tighten the cam-locks, the chuck or faceplate will snug up onto the spindle nose. When fully tightened, the cam-lock mark will fall between the two "V" marks on the spindle nose, as shown in Figure 26.

Note: To make sure that the chuck or faceplate is perpendicularly aligned with the spindle, use a test indicator mounted on the bedways to check for runout.
