上海机床厂专门制造磨床,品种较多,批量不大。中小型磨床的箱体类零件如头架、尾架、砂轮架及内圆磨具支架等,其轮廓尺寸多数不超过400×600×300毫米。孔的精度一般不低于2级。这些零件要经过铣(刨)平面、镗孔、钻孔、铰孔、攻丝及锪平面等多道工序,须从零件的几个方向进行加工。过去多数用普通机床。为了提高加工效率,试制了一台转塔式组合机床(见图1)。按照已配备的工艺装备,可以在不调换主轴箱只更换或拆下个别刀具的情况下加工七种零件。
Shanghai Machine Tool Plant specializes in manufacturing grinders, more varieties, small quantities. Small and medium-sized grinder box body parts such as the head frame, tailstock, wheel frame and inner circular grinder bracket, the outline size of the majority does not exceed 400 × 600 × 300 mm. Hole accuracy is generally not less than 2 levels. These parts are machined in several directions from part to part through multiple processes such as milling, boring, drilling, reaming, tapping and flattening. Most of the past with ordinary machine tools. In order to improve the processing efficiency, trial production of a turret combination machine (see Figure 1). In accordance with the equipment has been equipped, you can not change the spindle box only replace or remove individual tools in the case of seven kinds of parts processing.
