Mill Brass & Aluminum with a CNC Router
With the right techniques and tooling your CNC router can mill brass and aluminum with dependability, accuracy and consistency. Milling these materials on a home shop CNC router isn’t difficult, but milling metal requires a different and a disciplined approach. Here is a basic formula to get you started:
1. Stick with easily machinable alloys.
2. Choose the bit that is correct for brass or aluminum.
3. Mill at an RPM and feed rate that is right for your machine.
4. Use a light depth of cut.
5. Lubricate the bit.
6. Clear the chips.
