去年10月29日,苏联青年代表团团员、优秀青年车工费奥多罗夫同志,曾来我厂表演他的先进工作方法。在表演以前,他先向大家介绍了几种先进车刀,其中有一种是马尔科夫车刀。这种车刀在我厂采用的结果说明,它具有很多优点,并且是容易掌握的一种先进车刀。马尔科夫车刀的几何形状马尔科夫车刀的几何形状如附图,它是一种90°外圆偏刀。车刀的前角γ=10°,或其他适当的角度。车刀上磨有相当宽的倒棱,宽度是 f=0.5～3公厘。倒棱前角γΦ=-5°。硬质合金部分的主后角α=5°,刀杆部分的主后角α＇=7°;硬质合金
On October 29 last year, Comrade Outolov, a member of the Soviet Youth Delegation and outstanding young mechanic, once came to our factory to perform his advanced working methods. Before the show, he first introduced several advanced turning tools, one of which was Markov’s turning tool. The result of this turning tool used in our factory shows that it has many advantages and is an easy to handle advanced turning tool. The geometry of the Markov knife The Markov knife geometry is shown in the attached figure, which is a 90 ° outer circular knife. Rake angle γ = 10 °, or other suitable angle. Tool grinding a considerable width of the chamfer, the width is f = 0.5 ~ 3 mm. Chamfer angle γΦ = -5 °. The main relief angle α = 5 ° of the cemented carbide part and the main relief angle α ’= 7 ° of the shank part; and cemented carbide
