我厂钻头车间生产的大型钻头(φ32.6～φ60公厘、全长365～450公厘),是用高速钢 P9(刃部,长186.5～239.5公厘)和45号钢(柄部)焊接成的。按照过去的工艺方法,在车削这种钻头时,高速钢切屑和45号钢切屑是混在一起的。这混合的切屑每吨只值10元。该车间车工姚念想同志,就提出改进工艺方法的建议,使高速钢切屑和45号钢切屑分开。这高速钢切屑每吨值170元,而45号钢切屑每吨值20元。这样,每支钻头平均可车下0.5公斤的高速钢,每年可给国家创造2890元的财富。
Large drill bit (φ32.6 ~ φ60 mm, length of 365 ~ 450 mm) produced by our drill shop is made of high speed steel P9 (blade, length 186.5 ~ 239.5 mm) and No. 45 steel (handle) Welded In accordance with the past process, when turning the drill bit, high-speed steel chips and 45 steel chips mixed together. This mixed chip weighs only 10 yuan per ton. The workshop mechanic Yao Nian wanted to comrade, put forward suggestions to improve the process, so that the high-speed steel and 45 steel chip swarf separated. This high-speed steel chip per ton of 170 yuan, while the 45 steel chip per ton of 20 yuan. In this way, the average drill bit can be 0.5 kilograms of high-speed steel car each year to the country to create 2890 yuan in wealth.
