Light ball board is the main consumables when producing steel ball, and the surface quality of the light ball board will affect the steel ball surface quality, so it requires strictly on the light ball board surface quality and abrasive resistance, How to choose the cutting tools become an difficult problem.
Difficult producing problems:
(1)It is casting parts, the hardness will arrive HRC60, traditional cutting tools will be easily chipping
(2)Cast steel component will have large allowance and has big diameter, traditional cutting tools can’t finish one workpiece with only one insert, need change insert,which will affect the processing efficiency.
(3)Some large scale cast steel parts, it will be easily exist sand, stoma, ect casting defects. It will require high on the cutting tools toughness.
Halnn Solutions: We recommend BN-K1 solid cbn inserts for this situation, BN-K1 belong to solid cbn insert, is researched specific for roughing process with large allowance. And the CBN content of BN-K1 reach 90%, it has strong impact resistance, will not chipping when meet some casting defects.
