Originated from the Research and Development of Large Section Carbide Profile Insert Project set up by China’s Machinery Ministry, 1991, bearing cutting tools of Chengdu Tool Research Institute have been developed greatly for the last twenty years. CTRI offers a systematic solution in bearing turning and grinding application.

Cermet, a kind of insert material whose performance and application is between ceramics and carbide. It overcomes ceramics’ disadvantage of low strength, low toughness and low resistance to plastic deformation while demonstrates ceramics’ advantage of high hardness, low density, low friction coefficient to steel, good anti-oxidization, anti-corrosion, anti-wear and anti-chemical material diffusion; this material also has high strength and anti-impact property of carbide; this material’s hardness can reach to HRA93, bending strength can arrive to 2200MPa. Nowadays, cermet material has been widely used in bearing turning, metal cutting, wear parts and sealing parts field.

Parting off blade is used in the initial stage of pipe cutting, to cut the pipe into smaller sizes as preparation for bearing turning of chamfer, seal groove and raceway; It can also be used in trepanning operation to separate the inner ring and outer ring.
