Rough turning pump housing with BN-K1 solid cbn insert from Halnn Superhard

Normally the manufacturer will choose High chromium cast iron as the main materials of the industry pumps, but because of its high hardness of high chromium and the casting defects, the industry pump is difficult to machine. Common carbide insert and cbn insert both don't have good wear resistance. Choose the right cutting tools will be very important to improve the efficiency and lower the costs.

Nowadays, most industry pumps use high chromium cast iron as the main materials, which make the pumps more wear resistant than before. However the hardness of high chromium cast iron will be high and it also has some casting defects, In order to solve the problems, choosing the right cutting tools will be very important.

With carbide insert machine industry pump, the insert will wear rapidly,

leading to change insert frequently, which will affect the production efficiency, so carbide insert is not the right cutting tools for machining pump. Ceramic cutter only can be used for fine finishing.

In current times, only cbn inserts are the right cutting tools for machining pumps. Especially CBN inserts enterprise Halnn superhard researched BN-K1 solid cbn inserts, can be used for both rough machining and interrupt turning condition. The advantages of Halnn BN-K1 solid cbn inserts as follows:

1. High hardness
2. Excellent wear resistance
3. Impact resistance
4. Non-metal adhesive 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.
