1. Halnn Tools Rough turning pump housing with BN-K1 solid cbn insert from Halnn Tools

Because of the harsh environment of the industry pump, the usage life is short. In order to extand high tool life and high wear resistance, the manufacturers usually choose High chromium cast iron with high hardness, strength as the main materials for industry pumps, such as Cr15Mo3, Cr15Mo2Cu,Cr26,ect.The castings made of High chromium will have high hardness, large working allowance, and also have some defects, which made it difficult to machine.

The advantages of Halnn BN-K1 solid CBN inserts as follows:

(1)Impact resistance

(2)Non-metal adhesive solid CBN insert

(3)High hardness

(4)Excellent wear resistance
