Why choose Halnn CBN inserts BN-K1 to process slurry pump?

The following problems exist in the casting high chromium cast iron slurry pump

(1) high hardness

(2) large workpiece size, large margin

Some parts of slurry pump are intermittent, such as impeller with 5-12 blades, which belongs to the strong intermittent cutting condition, the traditional tool will collapse.

Advantage

At present, Halnn superhard as a CBN pioneer enterprise finally studied the BN-K1 CBN inserts with high efficiency cutting.

BN-K1 is an solid PCBN inserts specially developed for high hardness cast iron parts. The content of CBN reaches 90% and the hardness is about HRC98. It is the best choice for intermittent rough turning the slurry pump.

Application

The following is the user's feedback information on processing slurry pump housing with Halnn superhard BN-K1 CBN inserts.

Processing materials	High chromium cast iron
CBN Grade	BN-K1 CNMN120712-4S
Holder type	CCLNL2525M1207
Cutting parameter	Vc=75m/min，Fr=0.1mm/r，ap=3.5mm

Processing effect: When BN-K1 CBN tool is used to process high chromium casting slurry pump with large margin, not only the wear-resistance and impact toughness are excellent, but also the efficiency is improved. Moreover, BN-K1 inserts adopts dry cutting, which reduces the pollution of cutting fluid.
