CoilForm

Shaping the coilform at 30,000 rpm with a grinding burr being driven by the Foredom die grinding tool.

The lathe is being run at a more sedate speed of 55 rpm while the wire recess is being cut (ground) into place on the coilform, through the action of the grinding burr mounted in the handpiece, and clamped in place of the toolpost assembly on the compound slide.
