Ceramics have the characteristics of high hardness, strong wear resistance, high chemical stability and non-bonding to metals. Ceramics can be divided into traditional ceramics and advanced ceramics, among which new ceramics include structural ceramics and functional ceramics, and those used in the field of CNC tools Ceramics are structural ceramics.

Tools using ceramics as raw materials are mainly used for high-speed cutting and high-hardness materials that are difficult to process, and can also be used for cutting copper alloys, graphite, steel, engineering plastics, and composite materials. In addition to diamond, ceramics are another key upstream raw material for CNC cutting tools. Since the midstream CNC tool manufacturers have a wider selection of upstream ceramic raw material suppliers, the bargaining power of upstream ceramics is relatively low.
