Compound Rest; Four-Way Tool Post - Grizzly G0765 Owner's Manual

Compound Rest

The compound rest handwheel has an indirect-
read graduated scale. This means that the dis-
tance shown on the scale represents the actual
distance the cutting tool moves. The base of the
compound rest has another graduated scale used
for setting the cutting tool to a specific angle.

Tool Needed
Hex Wrench 5mm .............................................. 1
To set compound rest angle:
1. Loosen cap screws shown in Figure 41.

2. Rotate rest to desired angle, as indicated by
scale at base, then retighten cap screws.
Tip: The first time you set the compound rest
angle for cutting threads, mark the location
on the cross slide as a quick reference point.
This will allow you to quickly return the com-
pound rest to that exact angle the next time
you need to cut threads.

Four-Way Tool Post

The four-way tool post is mounted on top of the
compound rest and allows a maximum of four
tools to be loaded simultaneously.
Each tool can be quickly indexed to the workpiece
by loosening the top handle, rotating the tool
post to the desired position, then retightening the
handle to lock the tool into position.

To install a tool in the tool post:
1.
Adjust tool post screws so cutting tool can fit
underneath them (see Figure below).

Figure 42. Example of tool mounted in tool post.
Over-extending a cutting tool from the post
will increase risk of tool chatter, breakage,
or tool loosening during operation, which
could cause metal pieces to be thrown at
the operator or bystanders with great force.
DO NOT extend a cutting tool more than 2.5
times the width of its cross-section (e.g.,
2.5 x 0.5" = 1.25").
2.
Firmly secure cutting tool with at least two
tool post screws.
3.
Check and adjust cutting tool to spindle cen-
terline, as instructed in next subsection.
