Solved: Support for engraving with a ball end mill?
Yes, I use trace for something like a serial number with a line font. for something like a company logo or block letters engrave creates a nice toolpath but I'd prefer to use small ball end mills over chamfer mills. This just seems like it is unsupported. Likes. Back to Topic Listing.

How safe is it to ball mill
As far as ball mill safety goes, the motor should be completely separated from the milling area, so that no powder can get to the motor.

A ball end mill has NO flute at the tip of the tool. This means there is no cutting going on at the tip. You can actually argue that the very tip of the ball does not spin at all. The best place to machine with a ball end mill is on the side of the radius, between the tangent point of the radius with the straight side of the tool, and the tip.
