If you're on a true Swiss-type machine, you should only run pure cutting oils. Everytime I've seen people running water-based coolants, nothing but troubles with electrical and rust issues follow...sooner or later. Oils are what they're built to handle.
Back to the OP's problem: If your machine is stalling at only .005" into the part, you are probably running so slow that you're below the spindle drive's recommeded RPM range. No way should that stall a spindle, and none of the other methods mentioned are going to act any better on it. |
