硬质合金可转位(不重磨)式刀具从出现到现在不过三十几年的历史,然而由于它有着一系列的优越性,因此在国外工业发达国家中发展得非常快。尤其是最近十几年一些国家普及推广可转位刀具的速度是惊人的。例如:具有硬质合金生产先进水平的瑞典,1964年可转位式刀具产值仅占硬质合金刀具总产值的5%,1971年达到50%,而到1977年达到90%。美 Carbide indexable (non-reworked) type knives from the present to the present but thirty years of history, however, because of its range of advantages, it developed very rapidly in industrialized countries abroad. In particular, the popularity of indexable knives in some countries in recent decades has been staggering. For example, Sweden, which has an advanced level of carbide production, produced only 5% of the total carbide output in 1964, 50% in 1971 and 90% in 1977. nice
