Spindle Break-In

Before subjecting the lathe to full loads, you must break it in so that bearings will fully seat, gear teeth will find their normal wear pattern, and lubricant will be worked into the required areas. Otherwise, the moving components of the lathe may suffer from excessive wear.

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.

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 21.

2.Move the spindle switch to the left position, then run the lathe for ten minutes at each of the following approximate speeds: 50, 500, 900, 1800, and 2300 RPM.

3.Turn the spindle speed dial all the way counterclockwise to the minimum and move the spindle switch to the middle OFF position.

The maximum recommended spindle speed is 2300 RPM. DO NOT exceed this for more than a brief period of time or machine damage may occur.

4.When the spindle has come to a complete stop, move the spindle switch to the right position and run the spindle in reverse at 2300 RPM for another ten minutes.

5.Turn the spindle speed dial all the way counterclockwise to the minimum, move the spindle switch to the OFF position, and turn the master power switch OFF.

6.Check, and if necessary, re-tension the drive belts (refer to Adjusting Drive Belts on Page 55 for detailed instructions).

Congratulations! The spindle break-in is complete. Continue with the following Recommended Adjustments subsection.
