The grinder is a national 863 support project in 2008.The machine tool adopts the grinding method which is based on the grinding point cut. It does not need the auxiliary mechanism such as eccentric fixture, indexing device and so on. Using imported spindle system, the maximum speed of CBN grinding wheel can reach 120m/s. We have developed the interpolation software of the crankshaft cutting point tracking and grinding, and the grinding point of the grinding wheel is always following the rotation of the crankshaft to realize the high precision grinding of the crankshaft. The feed of the grinding wheel is driven by straight line, which has the characteristics of high acceleration response. At the same time, the rigidity and the sensitivity of the grinding wheel are improved by using the sel...
