我厂生产精密磨床的砂轮架主轴,数量颇大,除少数采用氮化工艺外,大都采用9Mn2V工具钢或GCr15滚珠轴承钢,经锻造、球化、调质及机加工后,采用中频淬火机表面淬火的方法。由于大部分主轴中间有一个凸缘,因此每根主轴在淬火时必须上下机床三次,(即先淬火好一端后,取下掉头后再上车,最后淬凸出的肩胛),而原来的淬火机床是用废的机床改装的,每次操作,至少要4人,一人按电钮,调整功率,一人负责摇尾架,一人上下料,一人指
I plant the production of precision grinding wheel spindle, a large number, with the exception of a few use of nitriding process, the majority of 9Mn2V tool steel or GCr15 ball bearing steel, the forging, balling, quenching and machining, the use of IF quenching machine Surface hardening method. Because most of the spindle has a flange in the middle, each spindle must be quenched three times up and down the machine (that is, after quenching a good end, remove the head and then get on the car, and finally quenched convex shoulder), while the original quenching Machine tool is used waste machine modification, each operation, at least 4 people, one press the button, adjust the power, one person responsible for the tailstock, one person on the loading and unloading, one person means
