Precision ceramic cutters
Main material for making precision ceramic cutters is the silicon nitride, these cutters can replace hard alloy cutter. Ceramic tool life is much more longer than traditional tool, reduce the times of changing tool, guarantee the taper and high precision in manufacturing; ceramic cutter can used for rough machining for high hardness materials, and also used for milling, plaining, interrupted cutting.
