近年来,随着机床性能、精度的飞跃提高,对控制刀具精度的重要性,有重新认识的必要。由于可转位硬质合金刀片的采用,在提高刀具质量和经济性方面都有很大的进展;但是高速钢和整体硬质合金刀具在刃磨方面还存在很大的问题。日本所用的工具磨床基本上全是万能型的。立铣刀磨沟机床、丝锥螺纹磨床等机床很 In recent years, with the improvement of machine tool performance and precision, it is necessary to re-understand the importance of controlling tool accuracy. Thanks to the use of indexable cemented carbide inserts, great progress has been made in improving tool quality and economy; however, there are still significant problems with high speed steel and solid carbide tools in sharpening. Tool grinding machines used in Japan are basically all-purpose type. Milling machine milling cutter, tap thread grinder and other machine tools
