Hi All ,,

I am making some upgrades for my cnc and thus im milling holes into aluminium to make the sides for my gantry.

Right now its taking me about 1 hour for each hole , but im thinking i could reduce that time alot if i could make it only lift about 2mm over each pass height to clear the chips instead of lifting to safe zone that is 5mm over the workpiece..

im making holes 9.5mm with a 4mm single flute endmill..

Any ideas on how that would be possible are appriciated as im still in the learning process " 1.5 years now ".. he he

Best regards ,,

Kristjan
