Hi All

I have a Sieg X2 mill converted to CNC and am just starting out on machining
- Spindle speed 0 -2000 rpm
- Not sure what feed rates I can go up to but it's a hobby machine
- Max endmill size 16MM
my main materials of choice will be Delrin and Acetal.

I just wanted advice on cutting speeds and feeds and also if I can get away with cutting dry. My research says that air blast is good for chip removal but I would prefer it if I can save the extra expense.

Also any advice on anything to do with machining the above is gratefully received

Thanks in advance :-)
