大家都知道在切削中以铣削速度为最快。根据这个道理,刘长荣、陈树仁同志就建议在大刨床上按装立铣头,结果提高了工作效率5倍,具体结构如附图。立铣头是按装在单柱式龙门刨床的横梁上,横梁的上下运动是通过机床底部的电动机(图中未画出),经过皮带轮和变 Everyone knows that milling is the fastest in cutting. According to this principle, Comrade Liu Chang-Rong and Chen Shu-Ren proposed that a milling machine should be installed on a planer bed, resulting in a work efficiency of five times higher. The specific structure is shown in the accompanying drawings. Vertical milling head is mounted on the single-column gantry beam, the beam up and down movement through the bottom of the machine motor (not shown), after the pulley and variable
