Top sales of long life CBN Cutting Inserts Cutting Mud pump with excellent wear resistance

1. Halnn Tools Top sales of long life CBN Cutting Inserts Cutting Mud pump with excellent wear resistance

In previous times, manufacturers choose carbide insert for machining

pumps, which has low efficiency, the reasons as follows:

• Industry pump are castings, it will have defects
• Carbide insert itself hardness is low, only can use low cutting speed

Then they try ceramic cutters, the characteristics are as follows

• High hardness, high strength, high red hardness
• Excellent wear resistance and stable chemical performance and low

Co-efficient fiction

Ceramic cutters can machine pump, but it is brittle, it will be easily chipping when meet casting defects, only can be used for fine finishing process.

CBN Inserts are mainly used for machining high hardness materials, the hardness is higher than ceramic insert and carbide insert, also can be used for high speed cutting, especially Halnn BN-K1 solid cbn insert.
