OPERATIONS
Replacement of Chuck
The head spindle holding fixture is cylindrical. Loosen
three set screws and nuts (A, Fig.17, only two are
shown) on the lathe chuck flange to remove the chuck.
Position the new chuck and fix it using the same set
screws and nuts.
Tool Set-Up
Clamp the turning tool into the toolholder.
The tool must be clamped firmly. When turning, the
tool has a tendency to bend under the cutting force
generated during the chip formation. For best results,
tool overhang should be kept to a minimum of 3/8” or
less.
The cutting angle is correct when the cutting edge is in
line with the center axis of the work piece. The proper
alignment of the cutting tool can be achieved by using
shims. For proper positioning reference the tool tip to
point of center mounted in the tailstock. If necessary,
use steel spacer shims under the tool to get the
required height. (Fig. 18)
Change H/L Speed
1. Unscrew the two fastening knobs (B, Fig.19) and
remove the protective cover.
2. Position the belt on the pulley as indicated in the feed chart.
A is low speed, B is high speed. (Fig. 20)
Caution: :e suggestRXUFXVWRPHUVto selectORZVSHHG
DVLWprovidesLPSURYHG torque!
Belt Adjustment
Loosen the four nuts and screws (C, Fig. 20).
Reposition the motor mounting plate to increase or
decrease the tension on the belt.
