Hand Polishing with CNC Lathe in Spindle Jog?

[alexlaughlin]

Is it an industry standard that it is acceptable to hand polish a rotating part inside a CNC machine while in MDI or Spindle Jog? Does OSHA have a publication or standard for this? Has anyone here operated a business or worked somewhere that an employee was injured or killed by doing so? Any help will be greatly appreciated.

This is generally regarded as a no-no. Manual lathes should have a footbar used to stop and brake the spindle, while cnc lathes have nothing of the sort. If your shirt sleeve, finger or arm were to be trapped or grabbed by the rotating machinery, just how do you propose to shut off the spindle?

OSHA would be happy to write up a 4 or 5 figure fine for doing this.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
