在车床或磨床上使用一种夹具,可以铣削、磨削椭圆柱孔。这种加工方法的特点是:(1)当椭圆柱孔的长轴和短轴相差较大时,或加工的椭圆柱孔较深时,如椭圆柱激光腔体等工件不需要剖开加工。(2)使用该夹具不仅能铣削加工椭圆柱孔,而且能磨削加工椭圆柱孔。(3)精铣加工表面光洁度达▽6,尺寸精度可达H8～H9;精磨加工表面光洁度达▽7～▽12,尺寸精度可达H6～H7。(4)对于不同长短半轴
Use a jig on the lathe or grinder to mill and grind the oval hole. This processing method is characterized by: (1) When the major axis and the minor axis of the elliptical column hole have a large difference, or when the machined elliptic column hole is deep, the workpiece such as an elliptical column laser cavity does not need to be cut open. (2) The use of the fixture not only milling elliptical column hole, but also grinding cylindrical hole. (3) Finishing surface finishing ▽ 6, the size accuracy of up to H8 ~ H9; fine grinding surface finish ▽ 7 ~ ▽ 12, the size accuracy of up to H6 ~ H7. (4) For different length of half-shaft
