高速钢(又名锋钢或风钢)刀具在机械加工行业中使用得非常广泛,因此,进一步提高高速钢刀具的质量,延长使用寿命,具有重要意义。锻造加工就是目前提高刀具內在质量、延长使用寿命最有效的方法之一。目前,高速钢锻造方面存在着两个比较普遍的问题:一个是怎么样降低 High-speed steel (also known as front steel or steel) tool in the machining industry is widely used, therefore, to further improve the quality of high-speed steel cutting tools, to extend the service life, of great significance. Forging process is to enhance the inherent quality of the tool, to extend the life of one of the most effective way. At present, there are two common problems in high-speed steel forging: how to reduce
