BN-K1 Solid CBN inserts Heavy Interrupted turning impeller
Impeller is one part of slurry pump, usually use High Chromium cast iron as main materials, Cr26 is one of the common materials. Every impeller include 5~12 pieces blade, machining these blades is strong interrupt cutting process, which will be high demanded on the inserts itself.
For turning high hardness alloy cast iron materials workpiece, the first choice must be CBN inserts. We need choose solid CBN inserts especially for strong interrupt turning process so that it will not chip in the process.
Halnn researched BN-K1 solid CBN inserts specifically for heavy interrupted turning condition, the CBN content reach 90%, hardness can reach HV3000~3250. The following will share you one application case
