我厂20毫米剪板机在1983年4月发现该刀架滑动导轨面磨损研伤严重,急需磨削加工进行精度修复。该件长3620毫米,宽1050毫米、厚220毫米。需磨削部分为1020毫米×120毫米。可是我厂没有导轨磨床。为抢修设备,采用了谭忠华技师提出的用Z35型摇臂钻床代替导轨磨床的方案,具体措施如下。 1.在摇臂钻床主轴上装一特制锥杆,其一端制成莫氏5~#锥柄与摇臂钻床主轴锥孔配
I plant 20 mm shears in April 1983 found that the carriage sliding rail surface wear serious injury, the urgent need for grinding precision repair. The piece is 3620 mm long, 1050 mm wide and 220 mm thick. The part to be ground is 1020 mm × 120 mm. But I plant no rail grinder. In order to repair the equipment, the proposal of using the Z35 type radial drilling machine instead of the guideway grinding machine proposed by the technician Tan Zhonghua was adopted. The specific measures are as follows. 1. In the radial drilling spindle installed a special tapered rod, one end made of Morse 5 ~ # taper shank and radial drilling machine spindle taper hole
