金属材实在切削加工时,通常,刀具的硬度要比工件的硬度高。在钻孔加工时,情况也相同。然而,在生产实践中常会碰到被加工工件的硬度比钻头硬度高,这时,采用常用的钻孔方法已无法加工,必须采用特殊的钻孔工艺来解决。本文用实际经验,介绍高硬度材料钻孔技术。 Metal cutting is actually, usually, the hardness of the tool is higher than the hardness of the workpiece. The same is true when drilling. However, in production practice, the hardness of the workpiece to be machined is often higher than the hardness of the drill bit. In this case, the common drilling method has been unable to process and must be solved by a special drilling process. In this paper, with practical experience, introduction of high hardness material drilling technology.
