我厂生产的3MZ143磨床,有一保持架零件(图1示),材料为酚醛胶木,毛坯为实心圆棒料,零件内径尺寸大。由于加工批量小,不适宜购置昂贵的套料刀。直接钻镗内孔,将85％的材料浪费掉,而且劳动强度大。为节省材料,降低劳动强度,我们制作了简易套料(?),经使用效果很好。 I produced the factory 3MZ143 grinder, a cage parts (Figure 1 shows), the material is phenolic Bakelite, rough for the solid bar, parts, large diameter size. Due to the small batch processing, not suitable for the purchase of expensive sets of knives. Boring the hole directly, will be 85% of the waste of materials, and labor-intensive. In order to save material, reduce labor intensity, we made a simple nesting (?), The use of good results.
