刀具结构如图1、2所示。刀具特点(1)能切削硬质合金无法加工的又韧又硬的各种HRC 62～70淬火钢、轴承钢、5F6、GR2、GR3和钛合金等。在某种意义上能代替磨削加工,加工光洁度可达(?)7～8,刀具耐热性强,耐磨性好,宜用于精车和半精车。(2)刀片采用机夹形式,结构简单,制造方便,免除了焊接的困难。刀具前、后角均为刀体制造的工艺所保证,刃磨方便,切削刃口磨损后刀片转动一个角度后可继续车削。当刀刃圆弧360°完全磨损时,可刃磨前刀面,调
Tool structure shown in Figure 1,2. Cutting Tools Features (1) All kinds of tough and hard HRC 62 ~ 70 hardened steel, bearing steel, 5F6, GR2, GR3 and titanium alloy that can not be machined by cemented carbide. In a sense, instead of grinding, machining finish up to (?) 7 ~ 8, tool heat resistance, good wear resistance, suitable for fine car and semi-fine car. (2) blade with clip form, simple structure, easy to manufacture, eliminating the welding difficulties. The front and back corners of the tool are all guaranteed by the manufacturing process of the tool body. The grinding is easy and the turning can be continued after turning the blade at an angle when the cutting edge is worn. When the knife arc 360 ° fully worn, the rake face grinding, transfer
