9.0 Operation
9.1 Tool set-up
The cutting angle is correct when the cutting edge
is in line with the center axis of the work piece. The
correct height of the tool can be achieved by
comparing the tool point with the point of the center
mounted in the tailstock. The correct tool height can
be obtained by using shims under the tool (Figure
13).
When turning, the tool has a tendency to bend
under pressure. For best results, tool overhang
should be kept to a minimum of 3/8” or less.
9.2 Manual turning
Apron travel, cross travel, and top slide handwheels
can be operated for longitudinal or cross feeding
(Figure 14).
9.3 Longitudinal turning with auto-
feed
To use automatic feed, establish the gear
combinations as needed, then move lever (A,
Figure 15) to engage feed.
