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 the chuck is
firmly seated against the face of the spindle all
the way around—without any gaps.
To install chuck:
1.
DISCONNECT LATHE FROM POWER!
2.
Use an appropriate lifting, support, or
protective device to protect ways and support
chuck during installation process.
3.
Clean and lightly oil camlock studs, then
thoroughly clean mating surfaces of spindle
and chuck.
4.
Install chuck by inserting camlock studs
straight into spindle cam holes.
Important: Avoid inserting studs by pivoting
them in from an angle or rotating the
spindle. This can damage studs or spindle
cam holes.
Installation & Removal
Devices
Because chucks are heavy and often awkward to
hold, some kind of lifting, support, or protective
device should be used during installation or
removal. The weight and size of the chuck will
determine the appropriate device to use (refer to
the following figure for examples).
