Hauk, I use two types of brass:
I purchase the material from a local dealer.
- Ms 58 (CuZn39Pb3) hard for flat and round material. The material is very easy to machine.
- Ms 63 (CuZn37) semi-hard for sheet metal. The material is easy to cold form.
I am relatively careful with the cutting values when milling. Under no circumstances should you use the values recommended by tool manufacturers for industrial use. I run the spindle at a maximum of 10,000 revolutions. Otherwise, because it is only air-cooled, it heats up too quickly.
I normally work with 2-tooth cutters with a diameter of 3 or 4 mm at a feed rate of 50 mm/min.
You have to work your way up a bit from the bottom. The optimum cutting data certainly also depends on the stability of the machine.
