Right cbn grade for rough machining pump---Halnn BN-K1

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.

Halnn superhard, with more than 10 years experience on super hard cutting tools(cbn

tools and diamond tools), researched Bn-K1 solid cbn inserts specific for machining pump parts. BN-K1 belong to solid cbn inserts, and the hardness will be higher than carbide insert and ceramic insert, also can be used for interrupt turning and large working allowance condition. With BN-K1 solid cbn inserts machining pump parts, the cutting speed will be about 3~5 times of carbide insert, so the efficiency is improved, and the tool cost is reduced.

The cutting data for machining pump with BN-K1 solid cbn insert

Common model insert model for machining industry pump: SNMN120712，

SNMN120708，CNMN120412，RNMN120400，SNMN120412, it can replace carbide insert, ceramic cutters and common cbn insert

Common tool holder model for machining industry pump: CSRNR3232(25*25 40*40) CSSNR3232(25*25 40*40) CCLNR2525(32*32 40*40)

BN-K1 solid cbn insert will be suitable for common lathe, CNC Lathe and others, it can

be used for milling, turning and boring process. It will help manufacturers solve most problems on machining pumps.

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.
