Uncoated bearing inserts suitable for finishing & semi-finishing applications. In different applications, Cosmos can provide the demanded grade of cermet with suitable strength and hardness. We are capable of providing products of different sizes based on customers’ demands, and controlling quality and tolerance. Typical customer-made products include measure tools, plates, valve core balls, pipe, etc.

Cosmos always provides our customers Cermet products with good quality, competitive price, fast delivery time and reliable after services.

Cermet grades are used in smearing applications where built-up edge is a problem. Their self-sharpening wear pattern keeps cutting forces low even after long periods in cut. In finishing operations, this enables a long tool life and close tolerances, and results in shiny surfaces.

The cermet may crack after electrical discharge machining (EDM).

Both dry cutting and sufficient cooling wet cutting are feasible. Avoid insufficient cooling and thermal shock in cutting.

• High Chemical stability, no buit-up edge ( no chemical interaction between workpiece and cutting edge)
• Excellent surface quality in continuous finishing machining
• Extraordinary wear resistance in continuous finishing machining
• Long tool life for finishing applications
• High red hardness and high cutting speed in dry cutting
