Indeed. Just one pass and I’m ready to make the die.
Since I was the guy that was doing the firing, I think I was pretty safe LOL
The “bigger” machine is faster for a few reasons:
–Higher RPM means I can cut processing time by significant amounts.
–Higher torque/ horsepower means I can use bigger tools, and take deeper cuts.
My 400v 3 phase 30amp 40,000 rpm spindle does a wonderful job!

Basically, the faster you can remove the chips, the faster you can go. Bigger tool = bigger chips = faster still. That’s where the larger faster spindle comes in to play. My finish passes with the tiny tooling:
Are still 5X faster due to the RPMs.
