摘要
针对目前国内制作钎焊金刚石/CBN砂轮的几种工艺方法,分析了存在的优缺点。根据工厂试验中出现的实际问题,指出了寻找到合适基体材料的方法,为解决高温钎焊对基体的影响提供了一个较好的样本。为了满足CBN/金刚石砂轮基体的力学性能需要,建议砂轮基体采用40Mn2这种材料,在700℃左右回火,其硬度可以达到38HRC左右,能够满足高速磨削和高精度磨削的要求。
According to several process methods on manufacturing the brazing diamond/CBN grinding wheel in the domestic market currently,the advantages and disadvantages of these methods are analyzed.In accordance with the actual problem occurred during factory tests: the welding temperature affects severely hardness of the grinding wheel matrix,and accordingly affects the accuracy consistency,a method for finding out a suitable matrix material is presented in this thesis,and thus a better sample is offered to solve the effect problem of the high-temperature brazing on the matrix.The conclusion is: to meet the dynamic performance requirements of CBN/diamond grinding wheel matrix,the 40Mn2 material is recommended for a grinding wheel matrix,its hardness can reach around HRC38 after temper at a temperature of around 700℃,and thus can meet the requirements of high-speed grinding and high-precision grinding.
