钎焊单层金刚石磨具的研究进展

Research progress of brazed monolayer diamond abrasive tools

钎焊单层金刚石磨具的研究和应用在国内外越来越受重视,与电镀单层金刚石磨具相比,钎焊单层金刚石磨具具有金刚石出刃高、容屑空间大、金刚石与基体之间的结合强度高等无可比拟的优点。从钎焊机理、钎料选择和钎焊工艺流程三方面介绍国内外钎焊单层金刚石磨具的研究现状,并分析大批量制造单层金刚石磨具存在的问题,指出下一步的研究有四项关键技术值得关注:钎料厚度的实用化控制、优质钎料的开发、钢基体受热变形、金刚石磨粒有序排布技术,为钎焊单层金刚石磨具的产业化提供借鉴。

The research and application of monolayer diamond abrasive tools have been paid more and more attention at home and abroad. Compared with electroplating monolayer diamond abrasive tools,the brazed monolayer diamond tools have the unparalleled advantages of high diamond cutting edge,large chip space,high bonding strength between diamond and matrix. In this paper,the research status of brazing monolayer diamond abrasive tools at home and abroad is introduced from three aspects：the blazing mechanism, the selection of solder and the process flow,and the problems existing in the large scale manufacture of monolayer diamond abrasive tools are analyzed,which provide reference for the industrial production of monolayer diamond abrasive tools.
