今年三月份,我们在郑州进行观摩推广先进刀具的活动中,学到了郑州客车厂阴(?)才师傅表演的一种专门加工内孔“8”字形油槽的工具。大家知道,各种轴套和瓦类内孔带有“8”字形润滑油槽,要比其它型式油槽的润滑性能好。但过去一般都用手工来加工“8”字形油槽,这样加工困难、操作紧张、效率低又保证不了质量。而这种加工内孔“8”字形油槽工具小巧玲笼、制造容易、使用方便、质量好并且生产率高。根本上解决
In March of this year, we conducted a tour of Zhengzhou to observe and promote advanced cutting tools. We learned from Zhengzhou Bus Depot Yin (?) Master a special tool for machining the “8” -shaped oil groove in the bore. We all know, all kinds of bushings and watts with a hole “” 8 “shaped lubricating oil groove, than other types of oil tank lubricating performance. However, in the past, the ”8“ glyph oil tank was generally processed by hand, which made it difficult to process, tight operation, low efficiency and no guarantee of quality. And this processing hole ”8 " shaped oil groove tool Ling small cage, easy to manufacture, easy to use, good quality and high productivity. Basically solved
