I was making something on the CNC mill last night. It is a little block that I would clamp to the quill of the mill, so that I would attach the Loc-Line coolant line to the quill. That way the coolant would follow the cutting tool as the quill is raised or lowered.
Anyway, as part of that, I had to drill a deep hole (comparatively). I used a peck drilling cycle and it worked, but took way too long, with withdrawal of the tool and lowering it down, etc.
So I wanted to double check what is the recommended procedure for deep drilling aluminum.
My feeling is that at the given RPM of 2400, I should have used a much more aggressive feed rate than I used.i
