For Machines Mfg. Since 7/09
Model SB1016/SB1036
OPERATION
The 4-way tool post is mounted on top of the
compound slide, and allows a maximum of four
tools to be loaded simultaneously. Quick indexing
to different tools is accomplished by loosening the
top handle, rotating the tool post to the desired
position, then re-tightening the handle to lock
the tool into position.

To load the tool post:
1. Choose the desired cutting tool.
2. Loosen the tool post bolts so that the cutting
tool can fit underneath them.
Note: If necessary, place one steel shim of the
required thickness underneath the cutting
tool, so the cutting tip is properly aligned
with the workpiece. The shim should be
as long and as wide as the cutting tool
to properly support it, a set of standard
automotive feeler gauges work well for this.

3. Firmly secure the cutting tool with at least
two tool post bolts shown in Figure 79.

Over-extending a cutting tool from the tool
post will increase the risk of it breaking during
operation, which may cause metal pieces to
be thrown at the operator or bystanders with
great force. Only extend a cutting tool 2.5
times the width of its cross-section or less
(i.e., 2.5 x 0.5" = 1.25").
Aligning Cutting Tool with Spindle
Centerline
For most operations, the cutting tool tip should
be aligned with the spindle centerline, as
illustrated in Figure 80.

There are a number of ways to check and align
the cutting tool to the spindle centerline. Below
are two common methods:
Align the tip of the cutting tool with a center s
installed in the tailstock (refer to instructions
that follow). For this to work, the tailstock
must be aligned to the spindle centerline
(refer to Aligning Tailstock on Page 44).
Make a facing cut on a piece of round bar s
stock. If the tool is above/below the spindle
centerline, a nub will be left in the center
of the workpiece. Adjust the height of the
workpiece, then repeat the facing cut to check
the adjustment. Repeat as necessary until the
center of the workpiece is smoothly faced.
