西德Guhring公司较早地在高速钢钻头上进行涂复碳化钛的试验,目前已研制成一种商品名为“S—钻头”投放市场。这种“S—钻头”在欧美国家的各个生产部门进行了切削试验。结果表明,与以往的高建钢钻头相比,刀具寿命提高了3倍,切削速度和生产效率均可大幅度提高。“S—钻头”具有如下一些特点: ①所用溶复方法与PVD法(物理气相沉积法)的离子涂复非常近似。反应过程中的温度在550℃以
West Germany Guhring company early in the high-speed steel drill bits coated with titanium carbide test has been developed into a trade name “S-bit” on the market. This “S-bit” has been cut in various production sectors in Europe and the United States. The results show that compared with the previous high-build steel drill bit, the tool life increased by 3 times, cutting speed and production efficiency can be greatly improved. The “S-drill” has the following characteristics: ① The dissolution-and-recovery method used is very similar to the ion plating of the PVD method (physical vapor deposition method). The temperature during the reaction is 550 ° C
