在加工如图1,φ50以下内球面时,用如图2内球面浮动车刀。经生产实践证明:这种刀具制造简单,操作方便灵活。加工工件一次成型,精度可达2级,光洁度达V_6以上。一、刀片设计计算: 加工内外园工件时,当刀具切削刃(刀尖)高于或低于工件(机床主轴)中心,这时切削平面与基面位移,形成偏心角B,从而使前 In the processing of Figure 1, φ50 the following spherical, the use of Figure 2 spherical floating tool. The production proved that: This tool is simple to manufacture, easy to operate and flexible. Machining a workpiece forming, accuracy of up to 2, finish V_6 above. First, the blade design calculations: When machining internal and external parts of the workpiece, when the cutting edge of the tool (nose) above or below the workpiece (spindle) center, then cutting plane and base displacement, the eccentric angle B, so that the former
