CBN cutting blades are made by attaching CBN abrasive particles and phenolic resin to a steel substrate through pressing, sintering under certain temperature, pressure, and vacuum conditions, and precision machining through various processing methods. Due to the strong grip of resin binder on boron nitride abrasive particles and ultra-high wear resistance, they are particularly suitable for precision cutting and slotting processing of tool steel, high-speed steel, mold steel, bearing steel, heat-resistant steel, stainless steel, and cast iron.

The resin bonded CBN cutting blade is a cutting tool widely used in the processing of quenched materials such as high-speed steel, alloy steel, and bearing steel. The cubic boron nitride cutting blade mainly consists of two parts; Matrix and blade. The matrix is the main supporting part for bonding the cutting edge, while the cutting edge is the part that starts cutting during use. The cutting edge is constantly consumed during use, while the matrix is not. The reason why the cutting edge can play a cutting role is because it contains CBN, boron nitride, which is currently the hardest substance second only to diamond. It rubs and cuts the processed object in the cutting edge. CBN particles are wrapped in metal inside the cutting edge.
