Spindle Break-In

Complete the spindle bearing break-in procedure to avoid rapid deterioration of spindle components when the mill is placed into operation.

The high-quality bearings and gears used in the mill are manufactured to very close tolerances. However, this does not guarantee perfect dimensional mating of the bearing components or exact meshing of gear teeth. Before operational stress is placed on these and other moving parts in the mill, complete this break-in procedure to conform these components to one another and ensure trouble-free performance from the mill.

To perform the spindle break-in procedure:

1.Successfully perform all the steps in the Test Run section beginning on Page 25.

2.Make sure the spindle is at a complete stop.

3.Set the spindle speed to the low range (refer to Setting Spindle Speed Range beginning on Page 37 for detailed instructions).

4.Start the spindle rotation at a medium speed and let the mill run for 20 minutes.

5.Stop the spindle rotation and allow the spindle to come to a complete stop by itself.

6.Set the spindle speed to the high range, then start the spindle rotation at a medium speed and let the mill run for another 20 minutes.

7.Stop the spindle rotation, and turn the mill OFF.

The spindle break-in of the mill is now complete!

Since the mill head was rotated parallel to the table for shipping purposes, you will need to tram the spindle with the table if your first cut requires a 90° alignment. Refer to the Tramming Spindle section on Page 33 for detailed instructions.
