Estimating burn depth is tricky. It depends on the thermal conductivity and specific heat capacity of the workpiece material, the maximum surface temperature reached and, most importantly, the time the wheel is in the grinding zone.

Say your machine shop just received an order for 316 stainless fuel-injector nozzles requiring angled holes to be drilled on the workpiece face. Or perhaps your best medical customer needs miniature blood-pump impellers with complex 3-D blade geometries like those on a jet-engine turbine. How are you going to make them?
