Spindle Break-In

Before subjecting the lathe to full loads, it is essential to complete the spindle break-in process as described below. This will ensure the best results and maximum life of the precision components inside the lathe.

The break-in procedure must be performed in succession with the Test Run procedure described in this manual, because many of the test run steps prepare the lathe controls for the break-in process.

Important: Do not perform the break-in procedure independently from the Test Run section—serious damage could occur to the lathe if the controls are set differently than instructed in that section.

Do not leave the lathe unattended during the Spindle Break-In procedure. If your attention is needed elsewhere during this procedure, stop the lathe and restart the procedure later from the beginning.

To perform the spindle break-in:

1.Successfully complete the Test Run procedure beginning on Page 26.

2.Using the spindle speed levers to set the spindle speed, run the lathe for 10 minutes at each of the spindle speeds starting with the lowest speed.

Note: If necessary, refer to Setting Spindle Speed on Page 50 for detailed instructions.

3.Use the foot brake to stop spindle rotation, set the spindle speed at 2000 RPM, then use the spindle lever to reverse the spindle rotation and run the lathe for 10 minutes.

4.Use the foot brake to stop spindle rotation, then run the lathe at 200 RPM for 10 minutes with the gearbox range lever on the headstock in the L (low) position, and then run the lathe another 10 minutes with the lever in the H (high) position.

5.While the oil is still warm and any metal particles are still suspended in the oil, change the headstock and gearbox oil (refer to Lubrication beginning on Page 66 for detailed instructions).

6.Check the V-belt tension, and if necessary, re-tension them (refer to V-Beltson Page 77 for detailed instructions).

Congratulations! The spindle break-in is complete.
