Chuck Installation

To ensure accurate work, it is extremely important to make sure the spindle nose and chuck mating surfaces/tapers are clean. Even a small amount of lint or debris can affect accuracy.

The chuck is properly installed when all camlocks are tight, the spindle and chuck tapers ﬁrmly lock together, and the back of chuck is ﬁrmly seated against the face of the spindle all the way around—without any gaps.

To install the chuck:

1.DISCONNECT LATHE FROM POWER!

2.Use an appropriate lifting, support, or protective device to protect the ways and support the chuck during the installation process.

3.Clean and lightly oil the camlock studs, then thoroughly clean the mating surfaces of the spindle and chuck.

4.Install the chuck by inserting the camlock studs straight into the spindle cam holes.

5.Incrementally tighten the camlocks in a criss-cross or star pattern to ensure that the chuck seats evenly against the spindle.

6.When the chuck is fully seated and all the camlocks are tight, verify that the cam line is between the two "V" marks on the spindle nose, as shown in the following figure.

Cam line between “V”s

Figure 30. Cam line positioned between the "V" marks

after the camlocks are fully tightened.

—If the cam line is NOT between the "V" marks when the camlock is tight, the stud may be installed at the incorrect height. To fix this, adjust the stud height as shown in the following figure. Make sure to re-install the stud cap screw afterward.

Important: Avoid inserting the studs by pivoting them in from an angle or rotating the spindle. This can damage studs or spindle cam holes.

—If adjusting the stud height does not correct the problem, try swapping stud positions on the chuck.
