在我厂生产的凿岩机上,有一个很重要的零件——转动格条筒套(图1)。它的花键表面光浩度过去达不到图纸6的要求,原因是由于零件结构所限,它的花链只能在插床或刨床上加工,不适宜采用拉力、推力或磨削加工。为了满足生产的需要,我们对现有花键表面增加了一道滚压工序,结果滚压的 In my factory production rock drill, there is a very important part - rotating grid sleeve (Figure 1). Its spire finish is far from the requirements of drawing 6 in the past due to the limited structure of the parts. Its chain link can only be machined on a slotted or planer machine and is not suitable for tension, thrust or grinding. In order to meet the needs of production, we added an existing spline surface rolling process, the result of rolling
