过去在工厂中光杠的键槽是用龙门刨床加工的,这样要耗费很多时间,机床的功率不能全被利用,获得的键槽质量也不高。 根据第一机械加工车间总施工员波尔菲利也夫同志的建议,改用车床铣切键槽,为此设计了一个按旋风铣削法来加工的专用刀盘(图1)。 刀盘由功率为2.2仟瓦,转速为1425
In the past in the factory light bar keyway is a planer processing, so to spend a lot of time, the power of the machine can not be fully utilized, the quality of the obtained keyway is not high. According to the suggestion of the chief constructor of the first mechanical shop, Porfierli Yev, a lathe was used to cut the keyway, and a special cutter disc machined by the whirlwind milling method was designed for this purpose (Fig. 1). Cutter by the power of 2.2 kilowatts, speed of 1425
