常见内球面的加工方法有:手工操作;靠模加工;蜗轮副机械传动,使刀具作定轴旋转切削和飞刀切削等数种。这里介绍一种新的加工方法,即“飞刀弦切削内球面”。它与上述方法相比,具有下列优点:一、由于球面直径取决于刀具位置,因此,刀头磨损或刃磨后,仍可保证球面直径。二、可大大缩小刀头直径(我厂取φ_刀=95毫米),使刀具制作方便,走
Common spherical processing methods are: manual operation; by die processing; worm gear mechanical transmission, the tool for fixed-axis rotary cutting and flying knife cutting, and so on. Here is a description of a new processing method, namely “flying knife string cut inner sphere.” Compared with the above method, it has the following advantages: First, since the spherical diameter depends on the position of the cutter, the spherical diameter can still be guaranteed after the cutter is worn or sharpened. Second, can greatly reduce the cutter head diameter (I plant take φ_ knife = 95 mm), making the tool easy to go
