高效率是国内外机械加工的主要发展方向之一。提高效率的重要方法,是提高切削、磨削速度及增大进给量。目前高速磨削已广泛应用于生产,普遍认为50m～80m/s的高速磨削是经济可行的,最高磨削速度已达到120m/s,试验室的速度已达到210～250m/s。现在有的工件实际磨削速度可以提高到300m/s。目前正朝着高速度磨削、强力磨削、高速强力磨削方向发展。 High efficiency is one of the main development directions of machining at home and abroad. An important way to improve efficiency is to increase the cutting, grinding speed and increase the amount of feed. At present, high-speed grinding has been widely used in the production, generally considered high-speed grinding 50m ~ 80m / s is economically feasible, the maximum grinding speed has reached 120m / s, the laboratory speed has reached 210 ~ 250m / s. Now some of the actual grinding speed of the workpiece can be increased to 300m / s. Currently moving towards high-speed grinding, grinding powerful, powerful high-speed grinding direction.
