Boron Carbide Machining & Grinding. Boron Carbide can be machined in green, biscuit, or fully dense states. While in the green or biscuit form it can be machined relatively easily into complex geometries. However, the sintering process that is required to fully densify the material causes the Boron Carbide body to shrink approximately 20%.
