Zirlux Acetal Partial

Wonder if freezing/ chilling the puck would help?

with Acetal you HAVE to go faster than normal milling, the material is extremely soft. bump your feed rate up and spindle speed up. with most people's standard pmma templates you could be going slowly enough that the tools just rub on the material which kinda makes it so that the tool itself gets warm and begins sticking to the material, jamming and breaking.

running faster/hotter for me causes tool breakage when milling acetal and PMMA. slower speeds give me repeatable and great results every time with no broken tools.
