我厂生产的小口径阀门,年产近三十万只。阀杆(图1)表面的加工一直用外圆磨床磨削,效率低、成本高,满足不了生产需要。为此,将一台ZA 28-80 A滚丝机改装成滚光机。采用滚压方法对机械零件表面进行光整加工,显著提高了零件表面的加工质量。滚光机(图2)有两个辊轮1、3,辊轮向一个方向旋转,工件2悬浮在托板6上,工件中心低于辊轮中心0.05～0.10毫米,朝着辊轮的相反方向旋转。这样具有碾压和滚压双重效应,能迅速提高零件表面的光洁度。一次滚
I plant the production of small-caliber valves, with an annual output of nearly 300,000. Stem (Figure 1) surface machining has been grinding with cylindrical grinder, low efficiency, high cost, can not meet the production needs. To this end, a ZA 28-80 A thread rolling machine converted into a roll machine. The use of rolling method of mechanical parts surface finishing, significantly improving the quality of parts of the surface processing. Rolling machine (Figure 2) has two rollers 1, 3, the roller rotates in one direction, the workpiece 2 suspended on the pallet 6, the workpiece center is lower than the center of the roller 0.05 to 0.10 mm, opposite to the roller Direction of rotation. This has the dual effect of rolling and rolling, can quickly improve the surface finish. Roll at once
