back and forth along the ways. Turning the
handwheel clockwise moves the carriage

the handwheel from rapidly rotating and
causing a potential hazard. To re-engage the

or retracts the carriage across the ways. This
motion may control the depth of a cut for a
turning or boring operation or may advance the
cutting tool across the face of a workpiece in a
facing operation.

Compound Handwheel

The compound handwheel (also known as the
compound feed) advances or retracts the
toolpost along
compound is set as indicated by the protractor.
The compound handwheel typically is used for
making short tapered cuts, limited by the range
of motion of the compound slide, and for
thread cutting operations.
handwheels have graduated collars that can
be used to measure the movement of the
cutting tool towards
workpiece. By grasping the graduated dial
while holding the handwheel steady, the
graduated dial can be set to a zero reading to
facilitate making a cut to a specific depth.
