OPERATIONS

Setting RPM

To determine and set the needed cutting RPM, do these steps:

1.Use the table in Figure 37 to determine the cutting speed required for the workpiece material.

2.Determine the average final diameter of the workpiece in inches, for the cut to be made.

Failure to follow RPM and feed rate guidelines may threaten operator safety from ejected parts or bro- ken tools.

3.Now use the following formula to determine the clos- est RPM for the cutting operation:

(Cutting Speed x 4) = RPM

Diameter of Cut

4.With the calculated RPM, decide on the closest cut- ting RPM to what you need.

5.Make sure the spindle is completely stopped before proceeding.

6.Move the levers (Figure 38) to get the RPM range that is closest to your calculated RPM:

•The range lever selects BLACK DOT = High or RED DOT = Low.

•The RPM Lever selects the RPM within that range.

Note: You may need to rotate the chuck by hand to get the gears to engage.

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 informa- tion.
