我厂生产的柴油机飞轮,直径为800毫米,需要在45°圆锥面上刻一圈5°一格长线。我们在立式铣床上加装了气动刻线装置(图1),将装置固定在立铣主轴4上,工件2放在转盘1上并固定。活塞杆6端头装有刀架和刀具,用螺钉将其紧固。采用4～5公斤/厘米~2的 I plant the production of diesel flywheel, a diameter of 800 mm, the need to engrave a circle in the 45 ° cone 5 ° a long line. We have installed a vertical milling machine pneumatic engraving device (Figure 1), the device is fixed to the spindle 4, the workpiece 2 on the turntable 1 and fixed. The end of the piston rod 6 is equipped with a tool holder and a tool, with a screw to tighten it. Using 4 to 5 kg / cm ~ 2
