Milling machines like a Storm Vulcan 85 B can leave a poor finish if the carbide cutters are not kept sharp and or the speed is too fast.

You hit some weld spots on factory blocks and just general wear causes them to leave a "file finish"after a while.

I ran one for years.....

I never got to use the CBN cutters and we never had a grinder....

Wheel had to be crated up and sent out or replace your own cutters but that was usually not a good scenario.......all it took was one cutter to be slightly high or low....

I have an old Van Norman rotary broach at home and it's a real dinosoar.....it needs to go to the scrap pile....
