Fan to blow away milling chips - Help needed
fatal-exception:
How about an aquarium pump. I think Hoss over there on the cnc zone uses one or more on his tricked out mini mill.
I don't worry about the chips anymore. I built a full plexiglass enclosure for my CNC router...close the doors and hit start. Vaccuum it out when done... :headbang:

But, as the mill cuts deeper, the chips accumulate in the cut path. They run through the cutter on each successive pass and give as much poorer finish as they are ground in between the cutter and workpiece. I used to use floor coolant to flush them away but it's a bit too messy. The finish without re-cutting the chips is noticeably better.

Dead right David, :thumbup:
Also less chance of breaking the small cutters.

A lot of vacuums will also blow air by attaching the hose to the exhaust. Then you can use the same gear.

You want to be very careful that you do not drive chips were you don't want them, ie in your eye, into the lead screw nut or under seals.
