Setting RPM
Whether using the vertical or horizontal spindle,
you need to 1) determine the RPM needed to cut
your workpiece, and 2) adjust the V-belts in the
access panel for the spindle you will use for the
operation.
To determine the needed RPM:
1. Use the table in Figure 13 to determine the
cutting speed required for the material of your
workpiece.
Cutting Speeds for High Speed Steel (HSS)
Cutting Tools
Workpiece Material Cutting Speed (sfm)
Aluminum & alloys 300
Brass & Bronze 150
Copper 100
Cast Iron, soft 80
Cast Iron, hard 50
Mild Steel 90
Cast Steel 80
Alloy Steel, hard 40
Tool Steel 50
Stainless Steel 60
Titanium 50
Plastics 300-800
Wood 300-500
Note: For carbide cutting tools, double the cutting
speed. These values are a guideline only. Refer to
the MACHINERY'S HANDBOOK for more detailed
information.

2. Measure the diameter of your cutting tool in
inches.
3.
Use the following formula to determine the
needed RPM for your operation:
(Cutting Speed x 4) / Tool Diameter = RPM
