Use on lever of high speed boring mount a PCBN boring cutter and sheet in couples piece boring cutter photograph is compared, it is good that its balance a gender, increased the tigidity of boring lever thereby, be in given below feed, use PCBN double razor blade to bore hole can obtain tall metal to excise rate and exterior quality. At present home already had more engine mill, the crock aperture to air cylinder body (or cylinder bushing) finish machining already used PCBN cutting tool. Be like the engine plant of Shanghai masses and one steam group, boring of crock aperture essence all uses PCBN bit and can compensate automatically (υ C=500m/min, f=0.

2mm/r, ap=0.

1mm) . Tall, dimension stabilizes the crock aperture precision that so treatment gives, and manufacturing efficiency is tall, cutting tool life is long. To alveolus boring, although can use pottery and porcelain or coating bit, but bit should contain the part before losing, this will increase cutting and the resistance that discharge bits, make lever of long and thin boring produces vibration easily. If use PCBN cutting tool to undertake high speed boring, the exterior quality of its aperture efficiency of good, production is tall. CNC Milling CNC Machining
