本文阐述了用小主偏角,大宽刃圆弧硬质合金车刀切削冷硬铸铁轧辊,提高生产效率的原理和方法。并介绍了与一机部工具研究所合作采用热压混合陶瓷刀具切削冷硬铸铁的切削试验研究情况,为进一步提高切削效率指出了方向。 This paper describes the principle and method of cutting the chilled cast iron roll with the small primary declination, the big wide-edge carbide carriages, and improving the production efficiency. The research on the cutting experiment of chilled cast iron using the hot-pressed hybrid ceramic tool in cooperation with a machine tool institute is also introduced. The direction is pointed out to further improve the cutting efficiency.
