Spindle Break-In

Before subjecting the spindle to operational loads, it is essential to complete the break-in process. This helps maximize life of spindle bearings and other precision components by thoroughly lubri- cating them before placing them under load.

The break-in must be performed in succession with the Test Run procedure described in this manual, as the steps in that procedure prepare the lathe controls for the break-in process.

DO NOT perform this procedure indepen- dently of the Test Run section. The lathe could be seriously damaged if the controls are set differently than instructed in that section.

To perform the spindle break-in:

1.Successfully complete the Test Run proce- dure beginning on Page 21.

2.Set spindle direction switch to "F" (forward), ensure range lever is in LOW, and operate lathe for 10 minutes at 100 RPM.

3.Operate lathe at 1000 RPM for 10 minutes, then turn variable speed dial to "0" to stop spindle.

4.Shift range control lever to HIGH, then oper- ate lathe at 2000 RPM for 10 minutes, then stop spindle.

5.Run lathe in reverse at 2000 RPM for 10 min- utes, then turn speed dial to "0", turn spindle direction switch to "0", and press Emergency Stop button.

Congratulations! Spindle break-in is complete.
