Choosing Spindle

RPM

NOTICE

Never shift gears while mill/drill or mill is running; otherwise, the gear teeth will be chipped or broken.

To determine and set the mill to the needed cutting RPM:

1.Select the cutting speed required for the material of your workpiece using the table in

Figure 15.

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

2.Measure the diameter of your cutting tool in inches.

3.Use the following formula to determine the needed RPM for your operation:

Note: You will only be able to get an approxi- mate rpm value with the gearbox range and reduction levers.

4.Move the mill gearbox levers to the nearest milling speed RPM.

NOTICE

Failure to follow RPM and Feed Rate Guidelines will shorten cutter life and give poor workpiece results and may threaten operator safety from ejected parts or broken tools.
