Mounting Chuck or Faceplate
The
To mount a chuck or faceplate:
1.DISCONNECT LATHE FROM POWER!
2.Lay a chuck cradle (see Figure 46) or plywood under the chuck or faceplate and over the bedway to protect the precision ground surfaces from damage and reduce injury if fingers get pinched.
3.Clean away debris and oily substances from the mating surfaces of the spindle and chuck or faceplate.
4.Inspect and make sure that all camlock studs are undamaged, are clean and lightly oiled, and that the camlock stud cap screws are in place and snug.
Never install a chuck or faceplate without having the camlock cap screws in place or fully tightened. If you ignore this notice, the chuck may not be removable since the camlock studs may turn with the camlocks and never release.
5.Position the chuck/faceplate in front of the spindle nose, align the chuck timing marks, as shown in Figure 49, and align the cam- lock studs with the sockets, then carefully insert the chuck or faceplate onto the spindle.
