Inside aperture of bore with a reamer of aperture of car of bore of method of 3 kinds of of aperture surface primary treatment

Bore 　 notices the following: 1) broach is brought to end panel, not usable power is too great, prevent broach and slant aperture. Bits of 2) getting deep aperture is not easy eduction, want to retreat the bit that get a platoon. 3) gets steel material, add note cooling fluid. 4) diameter is more than the aperture of 30 to divide second get 3 times (reduce obstruction horizontal ) when 5) broach will wear Kong Zuan, solid horizontal does not attend cutting, horn of cutting of broach of obstruction Xiaoyi attaint. Want to reduce feed amount. 2.

Car aperture: Can do be like, finish machining. Also be lathe work one of commonly used methods. 1.

After thick car, before fine vehicle, to book wall workpiece. Loosen card claw slightly. Be in gently clamp. 2.

Before Che Kongzhi, whether to try knife to be spent quite? Make mark. 3.

When aperture of car rank stage, lathe tool should form a point of view with workpiece end panel. 4.

Che Kongshi, hard alloy lathe tool must not add cooling dissolvent to turn juice. 2.

Aperture of bore with a reamer: The former firm with higher than quality of machine bore with a reamer aperture of hand bore with a reamer is: Cutting rate is low, temperature won't produce the tumor that accumulate bits not high. Change of cutting tool dimension is little, vibration is not had when cutting. Aperture of bore with a reamer uses: Lubricant engine oil, sulfurized oil. Bore with a reamer is cast-iron: Be not cheered or use kerosene, colza oil. CNC Milling
