十字轴是汽车万向联轴器中的一个零件。这个零件上的四个轴颈过去是在外圆磨床上加工,一次装卡只能磨一个轴颈,生产效率低,劳动强度大,远不能满足我国汽车工业飞速发展的需要。为此,我们准备在无心磨床上用双工位一次磨两个工件的新工艺来改变这种状况。但实现新工艺的关键是配
The cross shaft is a part of a universal coupling. The four journals on this part used to be machined on a cylindrical grinding machine. Only one journal can be worn at a time. The production efficiency is low and the labor intensity is too big to satisfy the rapid development of China’s automobile industry. For this reason, we are ready to change this situation with a new process of grinding two workpieces at a duplex station on a centerless grinder. But the key to realizing the new technology is matching
