1982年以前日本金属切削机床的产值是增加的,但1983年有所下降。硬质合金和高速钢刀具生产情况的变化也相似。刀具的产值约为机床产值的30％,但从1976年开始,由于数控机床生产的扩大和产值的增加而有所下降。从1980年至1983年无涂层硬质合金刀片的生产实际上无变化。在刀具总额中无涂层硬质合金由57.2％变为47.9％,涂层硬质合金由27％变为
Before 1982, the output value of Japan’s metal cutting machine tools increased, but declined in 1983. Carbide and HSS tool production changes are similar. The output value of the knives is about 30% of the output value of the machine tool, but from 1976 onwards, due to the expansion of the production of the numerical control machine tools and the decrease of the output value. There was virtually no change in the production of uncoated cemented carbide inserts from 1980 to 1983. Uncoated cemented carbide in the total tool change from 57.2% to 47.9%, coated cemented carbide from 27% to
