日本神户制钢所1989年初提高硬质合金刀具生产能力一倍。该厂1987年开发的印刷电路板孔加工用硬质合金小钻头的市场需要量急增;1988年开始出售的加工钢用涂层硬质合金钻头和1988年末开始形成系列化的超高微细硬质合金立铣刀的需要量也大增。目前神户制钢所已形成高速钢、硬质合金综合切削工具制造厂。
Kobe Steel in Japan in early 1989 to improve carbide tool production capacity doubled. Market demand for cemented carbide drills for PCB hole processing developed at the plant in 1987 has soared; coating cemented carbide drills for processing steel started to be sold in 1988 and a series of ultrahigh-fine hard The demand for quality alloy end mills also increased sharply. At present, Kobe Steel has formed a high-speed steel, carbide cutting tool manufacturing plant.
