一般来说,薄壁工件的加工是比较困难的,如图1所示的薄壁工件,其壁厚只有1mm,且直径较大,还要热处理。一般的加工方法是先粗、精车外圆、内孔及端面,热处理,然后再磨内孔、磨外圆。因热处理变形,磨内孔时如以外圆定位,则由于弹性变形,很难保证内孔的圆度和同轴度。 In general, thin-walled workpiece processing is more difficult, as shown in Figure 1 thin-walled workpiece, the wall thickness of only 1mm, and larger diameter, but also heat treatment. The general method of processing is coarse, fine car cylindrical, bore and end, heat treatment, and then grinding the hole, grinding cylindrical. Deformation due to heat treatment, such as grinding the inner hole to locate the outer circle, then due to elastic deformation, it is difficult to ensure the roundness of the hole and coaxiality.
