Chromium Carbides
Grinding of Powders. The grinding of the chromium and the chromium carbide are both carried out in mills. There is always a risk of explosion when grinding fine metal powders and the mills are specially designed to deal with potential hazards such as this. Cryogenic cooling (liquid nitrogen) is also applied to the mill to facilitate grinding.

Cutting through cobalt chrome
Another significant consideration is that cobalt chrome is very heat-resistant with low thermal conductivity. During cutting of standard steels, heat generally is evacuated through the chip. However, with cobalt chrome, heat does not generate into the chips. Because of this, the heat concentrates at the cutting edge of the tool," said Doiron.

Grinding Balls and Other Grinding Media: Key consumables
Tower Mills: 0.5"-1.5" grinding balls are recommended. The normal top size of media used is 10-25mm, but even smaller grinding balls can be used for very fine grinding. Isa Mills: <0.1" grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls).
