近年来少切削无切削新工艺巳在全国范围内得到了普遍重视和广泛应用,这是我国机械制造工艺水平普遍提高的重要标志之一。这些工艺的一个共同特点是:形变能量大、速度快、生产率高、产品质量好以及用料省等。但模具使用寿命低,以致严重妨碍这些新工艺的稳定投产和进一步的发展。
In recent years, cutting-free cutting new technology has been widely valued and widely used throughout the country, which is one of the important symbols of the general improvement of China’s machinery manufacturing technology. A common feature of these processes is: large deformation energy, high speed, high productivity, good product quality and materials and so on. However, the service life of the mold is so low that it seriously hinders the steady operation and further development of these new processes.
