工件表面光洁度如要加工到▽12以上是比较困难的。这里介绍一种采用对轮珩磨加工的方法,可使轴类零件表面光洁度达到▽13以上。机构将普通车床横向拖板和横向丝杠拆下,装上一根左右螺纹丝杠和两块滑板(见图1),两滑板下边各装一螺母,摇动丝杠3可使两滑板4同时向中心移近或离开。在两滑板上各装一只珩磨架,并使两珩磨轮10旋转中心线与车床主轴旋转中心线各成45°(一个左转
Surface finish of the workpiece to be processed to ▽ 12 or more is more difficult. Here introduced a method of using wheel honing, shaft parts can make the surface finish ▽ 13 or more. Institutions will be ordinary horizontal lathe horizontal and vertical screw removal, with a left and right threaded screw and two skateboards (see Figure 1), two sliders each with a nut, shake the screw 3 allows the two skateboards 4 at the same time Move closer to the center or leave. A honing machine is mounted on each of the skateboards, and the centerline of rotation of the two honing wheels 10 and the center line of rotation of the lathe spindle are each at 45 ° (a left turn
