一、生产日本1985年固结磨具生产量为65385吨,生产值为597亿日元,按产品分类的产量详见表1。按表1的磨具生产量、生产值与以前年度的产量统计数比较,可推测日本磨具生产发展的动向。生产量(按磨具重量计算的生产量)日本固结磨具1969年产量76892吨,1970年83360 I. Production Japan In 1985, the production of bonded abrasives was 65,385 tons, and the production value was 59.7 billion yen. See Table 1 for the output by product classification. Comparing the production volume of the abrasive tools in Table 1 with the production statistics of the previous year, it is possible to speculate the trend of the production and development of Japanese abrasives. Production volume (production amount by weight of grinding wheel) Japan consolidated abrasives output 76,688 tons in 1969, 1970 83340
