Compared the performance between Halnn Bn-K1 solid cbn insert and coating carbide insert on machining pumps

 In order to make sure long working time of the industry pump, the manufacturers usually use high chromium cast iron as the main materials, like the main parts pump casing and impeller. But high chromium cast iron parts belong to castings, it will have and, stomach problems, belong to interrupt turning condition, which will be difficult to machine. And the pumps also have high hardness, the insert need to obey high impact resistance, and will produce high temperature, and make the tools edge wear rapidly. So choosing the right cutting tools will be very important to help the manufacturers improve their efficiency and extand its life.

The most suitable cutting tools for machining pump are cbn inserts. And

BN-K1 solid cbn insert is researched specific for machining high hardness cast iron parts. It has excellent wear resistance and impact resistance, the content of cubic boron nitride can reach 90%, the hardness is around HRC95~100. When machining pump with BN-K1 solid cbn inserts, it will improve the efficiency and lower the production costs.

 The application case of Bn-K1 solid cbn insert machining pump impeller: materials is high chromium cast iron, process is Cylindrical and surface, insert is Halnn BN-K1 solid cbn inserts,the cutting data are vc=75m/min, ap=2.5-5mm, f=0.1mm/r, the machining type is interrupt turning condition, dry cutting. Machining Effect, BN-K1 solid cbn insert is not chipping when meet interrupt turning condition, and compared with ceramic cutters, the cutting speed is higher, and the tool life is about 7 times more than ceramic cutters, which show the excellent impact resistance. BN-K1 solid cbn insert also help manufacturers improve the process efficiency and reduce the tool costs.
