苏联乌拉尔机器制造厂采用镶陶瓷刀片的切刀,在大型普通车床、立式车床、镗床,其中包括数控机床上精加工大型零件、设计时选用的是标准结构的车刀,刀片机械夹固在刀杆槽内,并调整成后角α=7°和前角γ=-7°。为使刀片具有可靠的刚性支承,采用了经磨削过的硬质合金支承垫片。下面介绍几种用于重型机床上的切刀结构。图1所示是用于车床(中心高800mm,中心距6000mm,)和镗床(主轴直径180mm)上的切刀。同标准切刀相比,其刀杆1的截面积有所增大。刀片5放在支承垫片6上,通过螺栓3和压板2从上部压紧断屑块4和刀片。采用这种切刀可以改变许多零件的加工工艺。例 Ural machine factory in the Soviet Union with a ceramic blade inserts the knife, in large lathe, vertical lathe, boring machine, including CNC machine tools finishing large parts, the design is the choice of the standard structure of the turning tool, blade clamping machine Arbor slot, and adjusted into the relief angle α = 7 ° and rake angle γ = -7 °. In order to make the blade with a reliable rigid support, the use of the carbide bearing gasket has been ground. Here are some of the cutter structure for heavy machine tools. Figure 1 shows a cutter for a lathe (center height 800 mm, center distance 6000 mm) and a boring machine (spindle diameter 180 mm). Compared with the standard cutter, the cutter 1 has increased cross-sectional area. The blade 5 is placed on the support washer 6 and the chip breaker 4 and the blade are pressed from above by the bolt 3 and the pressure plate 2. Using this cutter can change many parts of the processing technology. example
