Even if a tailstock and steady rest are used,
the maximum speed rating may not be
SAFELY reached with certain workpieces.
The workpiece must be balanced and
appropriately sized for the chuck and lathe,
and the chuck must be properly maintained
to achieve maximum clamping force. As
spindle speeds increase, centrifugal force
also increases. If centrifugal force becomes
too great, the workpiece can be thrown from
the chuck with deadly force. Always use good
judgment with each setup!
Specifications
Introduction
Incorrect use of this tool
can result in death or
serious injury. For your
own safety, read and
understand this entire
document before using.
This chuck uses a direct-mount camlock system
to attach to the spindle. Direct-mount chucks
provide a number of advantages over chucks that
require a back plate for mounting.
The main benefit is a larger maximum working
area between the chuck jaws and tailstock. The
increased space is created by the absence of a
back plate between the chuck and spindle.
Another benefit is that direct-mount chucks
require less initial setup time because the
machinist is not required to machine a back plate
to fit the chuck.
