机夹不重磨式刀具在五十年代初,首先在一些机械工具比较先进的国家使用。经过二十多年的生产实践,证明是一种比较经济的刀具。目前瑞典的山特维克(SANDVIK)公司在十九个国家建立了分公司大量生产这种刀具。我国机械工业战线上的职工在五八年也创造了具有我国风格的各种机夹不重磨式刀具,由于刘少奇一类骗子的干扰,使这一工作的推广和发展速度受到了一定影响。随着机械工业的迅速发展,高速切削达到很高的水平,硬质合金焊接重磨式刀具已
Machine folder does not regrind cutter in the early 1950s, the first in some more advanced mechanical tools used in the country. After more than two decades of production practice, proved to be a more economical tool. At present, SANDVIK in Sweden has set up branches in 19 countries to mass produce such knives. In 1988, the workers on the frontline of China’s machinery industry also created all kinds of machine-type non-worn cutting tools with Chinese style. Due to the interference of a class of liar like Liu Shaoqi, the promotion and development speed of this work have been affected to a certain extent. With the rapid development of machinery industry, high-speed cutting to a very high level, carbide grinding machine tool has been
