我厂自生产c630车床以来,床头箱的主轴轴孔(φ70～1080),以前系采用钻削与搪加工,既费工时,又费材料,同时工人的劳动强度也大,在学习外厂经验的基础上,经过生产中的多次实践,现改成套料加工,孔径效果良好,我厂加工系在加长c630车床上进行的,现介绍如下: 一、概述:该套料刀的刀头用方牙螺纹,54×3装于刀杆上,刀杆装夹在拖板支承上,前段用中心架支承。 Since the production of the c630 lathe, the spindle shaft hole (φ70~1080) of the headstock has been used for drilling and boring in the past. This is not only time-consuming but also material-consuming. At the same time, the labor intensity of the workers is also large. On the basis of experience, after many times of practice in production, it is now converted into nested material processing, and the aperture has good results. Our factory processing is carried out on the extended c630 lathe, and is introduced as follows: I. Overview: The knife of the set of material knife The head uses a square thread, 54×3 is mounted on the arbor, the arbor is clamped on the carriage support, and the front section is supported by the center frame.
