Customer requirement: improve processing surface quality, reduce tool cost

Comprehensive evaluation: Meet customer roughness requirement. According to the tool wear analysis, the HALNN tool wear is lighter than the current tool, still could continue processing. There is no breakage, just normal wear, solve the anti-breakage property of insert, lmprove the stability of cutting tools.
