日本的切削工具工业在工业化世界中,是增涨得最快的工业部门之一。虽然这一工业部门就其工艺和生产量而言,可以认为已达到了国际水平,但是它有一个固有的弱点,就是对进口原料的依赖性,这样便产生了一个按稳定价格保证得到原料稳定供应的问题.日本的切削工具工业在1978年4月至1979年3月期间共生产硬质合金1190吨,这些硬质合金的生产主要分布在三家最大的公司:三菱金属公司、住友电气工业公司、东芝钨有限公司,另外还有戴捷托工业公司,它们的产量占全日本的75%,其余部分则由其他的25家工厂生产.1973年的石油危机和由此而引起的生产下降和通货膨涨,严重地影响了日本硬质合金的生产。从统计数字可以看出,1975年是最低点,产量只有822吨。据估计,1979—1980年的产量将比1978—1979年的产量增加10%。
Japan’s cutting tool industry is one of the fastest growing industrial sectors in the industrialized world. Although this industry sector can be considered to have reached the international level in terms of its process and production volume, it has an inherent weakness, that is, its dependence on imported raw materials, so that a stable price is guaranteed to stabilize the raw materials. Supply problems. Japan’s cutting tool industry produced 1,190 tons of cemented carbides between April 1978 and March 1979. The production of these cemented carbides is mainly distributed among the three largest companies: Mitsubishi Metals, Sumitomo Electric Industries, Ltd. Toshiba Tungsten Co., Ltd., as well as Daijeto Industrial Co., Ltd., accounted for 75% of Japan’s production, while the rest was produced by 25 other factories. The oil crisis in 1973 and the resulting decline in production and currency Swelling has seriously affected the production of cemented carbide in Japan. From the statistics, it can be seen that 1975 was the lowest point and the output was only 822 tons. It is estimated that the output from 1979 to 1980 will increase by 10% from the output from 1978 to 1979.
