近来我们在机加工中应用了我国自行研制的新型冷却润滑剂:即10#、20#、30#极压切削油,取得了一定的效果,如工件光洁度一般都能提高两级,刀具耐用度成倍增加。尤其是成型刀切削效果更显著。现将应用情况简析于下。 在金属切削过程中,前刀面和切屑、后刀面和工件之间的摩擦,大多?
Recently, we applied a new type of cooling lubricant developed by our country in machining: 10 #, 20 #, 30 # extreme pressure cutting oil, and achieved some results, such as workpiece finish generally can improve two levels, the tool durability Exponentially increase. In particular, forming knife cutting more pronounced. Now the application of the situation in the next. In the metal cutting process, the rake face and the chip, the flank and the friction between the workpiece, mostly?
