通常圓柱形蝸杆都用成形車刀或盘形銑刀加工。我厂过去在車床上加工图1所示的双头蝸杆时,效率低而且齿形不易控制,质量很难保証,是生产中的一个薄弱环节。經过长时期的試驗研究后,改用冷軋法在自制的滾絲机上軋制,已获得成功,能提高质量、降低成本、提高生产效率。現介紹如下,供参考。 Usually cylindrical worm with a forming tool or disc cutter processing. I plant in the past on the lathe machining shown in Figure 1 double-headed worm, the inefficient and difficult to control the toothed, the quality is difficult to guarantee, is a production link. After a long period of experimental research, the use of cold rolling in the rolling machine rolling, has been successful, can improve quality, reduce costs and increase production efficiency. Now introduced as follows for reference.
