硬质合金滚刀是用于加工硬齿面齿轮和改革普通齿轮加工方法的一种新型工具。这种工具在制造上存在着一定困难,其中刀片与刀体的连接是最大关键。起初,滚刀制造业的工程师们曾试图用机械固定、胶接、火焰钎焊、高频钎焊等方法来连接硬质合金刀片与刀体,都没有获得满意的效果,七 Carbide hobs are a new tool for machining hardened gears and for reforming ordinary gears. This tool in the manufacturing there are some difficulties, including the blade and the body is the key to the connection. At first, the hob manufacturing engineers had tried to use the mechanical fixing, gluing, flame brazing, high-frequency brazing and other methods to connect the cemented carbide blade and the blade body, have not been satisfactory results, seven
