Spindle Break-In

The high-quality bearings and gears used in this lathe are manufactured to very close tolerances. 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 incorrectly when the break- in procedure is started.

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 28.

2.Set the spindle speed for 40 RPM (refer to the Setting Spindle Speed subsection on Page 51 for detailed instructions).

3.Run the lathe for 10 minutes.

4.Turn the lathe OFF and wait until the spindle is completely stopped.

5.Repeat Steps 2–4for each of the remaining 15 spindle speeds.

6.Set the spindle speed to 40 RPM and let the lathe run for a final 15 minutes to allow it to cool down, then turn the lathe OFF.

7.Change the oil in the headstock, quick- change gearbox, and apron reservoirs as instructed in the Lubrication subsection on Page 67.

8.Check and, if necessary, re-tension the V-belts as instructed in the V-Beltsubsection on Page 80.

Congratulations! The spindle break-in is complete.
