我们作了一套简单的通用胎具,在小镗床上成功地加工了图1所示零件。考虑到一般此类零件孔与底板的平行度要求不高,故底板可不加工,其胎具结构和装夹方法如图2所示。滑板和滑道毛坯用铸铁或用型钢组焊而成。加工时滑板的下平面的平面度、滑道上、下平面的平面 We made a simple set of universal molds that successfully fabricated the parts shown in Figure 1 on a small boring machine. Taking into account the general hole of such parts and the bottom of the parallelism is not demanding, so the floor can not be processed, the structure of the tire and the clamping method shown in Figure 2. Skateboarding and chute rough with cast iron or steel welded together. The flatness of the lower plane of the skateboard during processing and the plane of the upper and lower planes of the slideway
