我们时常会遇到大尺寸内、外圆柱面的光整加工问题。例如XZ3112多触头高压造型机的大型铸钢件(ZG35)压活塞(见图1)的内、外圆柱面的精加工就十分典型。目前,国内最大规格的磨床加工范围仅限于外圆800毫米以下,内孔500毫米以下,而且一般工厂都不具备这样的设备条件,即使有这类大型磨床的厂家,设备利用率也甚低。我们设法在普通卧式或立式车床上应用砂带磨削工艺解决这个问题,并已取得很好的效 We often encounter large-size, cylindrical surface finishing problems. For example, XZ3112 multi-contact high-pressure molding machine of large castings (ZG35) pressure piston (see Figure 1), the outer cylindrical surface finishing is very typical. At present, the machining range of the largest grinder in China is limited to 800mm OD and 500mm ID, and most factories do not have such equipment. Even those with such large grinders, the utilization rate of equipment is very low. We have managed to solve this problem by applying a belt grinding process on a normal horizontal or vertical lathe and have achieved very good results
