近代工业生产的发展,出现了许多巨型机床。如一些龙门刨、龙门铣的床面,一般由几公尺到十几公尺长,个别的有近百公尺的。这些机床上切下的切屑,当初加工时,其断面往往很大,用人工清除切屑显然是十分麻烦的。另外,切屑如不及时清除,对工作也会有影响,一些崩碎的切屑微粒会落在床 The development of modern industrial production, there have been many giant machine tools. Such as some gantry planing, gantry milling bed, usually a few meters to ten meters long, individual nearly a hundred meters. The chips cut on these machine tools, the initial processing, the section is often large, with manual removal of the chip is obviously very troublesome. In addition, if not timely removal of the chip, the work will have an impact, some broken chip particles will fall on the bed
