BN-K1 Solid cbn---the most suitable cbn grade for machining industry pumps

With the development of the modern technology, most industry will need pumps with high efficiency and excellent wear resistance.

In order to meet all the requirements on the pumps, the manufacturers will add Cr element in the pumps which will get better wear resistance and high hardness. It is called high chromium cast iron. And this type pump parts will have casting defects, like sand, white mouth,ect. It will be more difficult to machine.

The problems of difficult to machine pumps:

(1) The material of industry pump is high chromium cast iron, the hardness after castings is high, traditional cutting tools can’t machine.

(2) The working allowance is large, and it also have some defects, such as sand, hard pot, it will require high on the wear resistance and impact resistance.

(3) Machining industry pump belong to interrupt turning condition, however traditional cutting tools can’t use.

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.

When machining industry pump, we can choose the cutting tools depending on the workpiece hardness, materials,working allowance, and choose the insert model depending on the machining site, so when before you bought the cutting tools, please contact with us halnntools@gmail.com, or skype:cbn_inserts_angels,then we can help you choose the right grade and model for you.
