Hello! We are having difficulties with aluminium block binding on the tool as it cuts. We are using a 2600pro and the ali (we are assured by our supplier) is free chipping quality. What is the recommended feed and speed for 1/4 " ball nose cabide cutter? Any advice will be greatly apreciated. Cheers, Dan

what speeds and feeds are you running at?
The centre of the cutter will have a lot slower surface speed than the diameter which will always make cutting in aluminium a little harder.
I would try about 12000 RPM and look at 600 to 800mm/ min.
Take the depth of cut to about 1 or 2 mm.
Depending what you are trying to do the problem can be caused by the chips being trapped and rubbed against the side of the tool causing friction.
