Silicon Nitride Diamond Grinding and Precision CNC

My ceramic part is fired and needs to hit tolerance. Who grinds it without introducing subsurface damage?

What it is

Multi-axis machining of fired ceramic using diamond-grit wheels under continuous flood coolant. Nothing softer than diamond will cut a sintered ceramic, and heat or shock during grinding initiates the cracks that later fail the part.
