Setting Spindle Speed

The Model SB1024 uses a variable pulley system to set infinite speeds within the speed range selected. The Model SB1025/SB1026 requires re-positioning the V-belt on the pulleys to change spindle speed.

Use the appropriate section below for the mill to select the correct spindle speed.

For the Model SB1024 ONLY, always make sure that the spindle rotation has been started and is at a constant speed before using

the variable speed handwheel to adjust the spindle speed. Otherwise, the moving parts inside the belt housing could be damaged and void the warranty.

Setting SB1024 Spindle Speed

1.Start the spindle rotation.

2.Slowly rotate the speed handwheel shown in Figure 34 until the desired speed is displayed in the speed indicator window for the speed range selected.
