Re: CNC Aluminum: Recommended Speeds/Bits?

We just got a CNC Router this past Sept and started cutting Aluminum with some success starting last week.

Last night we made custom drivetrain plates from 3/16" 6061 Aluminum.

We have been using a 5/16th end mill while waiting for our shipment of

Onsrud
G1817076 Upcut Spiral O-Flute
and
G3168471 Straight O-Flute bits.

Spindle Speed - 10,000 RPM
Feed Rate - 20 IPM
Plunge Rate - 10 IPM

*Make sure you have coolant. We are using a spray system with a vegetable base spray.

Let me know if you need anything else and good luck
