我厂加工的硬质合金拉伸模具原来采用1:5高锰酸钾、三氧化二铬研磨与抛光,加工效率低,劳动强度大,废品率高,作业条件差,对工人身体有害。我们改用500~#碳化硼和JRW油溶研磨膏(2.5~#3.5~#, 5~#,10~#)进行研磨与抛光后,取得了提高工效,改进质量,改善劳动条件,降低成本的效果,光洁度可达10～13。以φ10毫米左右的几种孔形零件为例,其加工过程为:硬质合金毛坯一内磨(金刚石砂轮)一研磨(500~#碳化硼)一抛光(JRW油溶研磨膏)。内磨
I plant the processing of carbide tensile mold originally used 1: 5 potassium permanganate, chromium oxide grinding and polishing, low processing efficiency, labor-intensive, high rejection rate, poor working conditions, harmful to the workers. We use 500 ~ # boron carbide and JRW oil-based abrasive paste (2.5 ~ # 3.5 ~ #, 5 ~ #, 10 ~ #) after grinding and polishing, and achieved improved work efficiency, improve quality, improve working conditions and reduce costs The effect of finish up to 10 ~ 13. Take several hole parts of φ10mm for example. The machining process is as follows: a carbide grinding wheel (internal grinding wheel) grinding (500 ~ # boron carbide) polishing (JRW oil grinding paste). Internal grinding
