介绍新型立式钢球研球机3M7280的特点，其采用上盘减速电动机驱动丝杠加压，消除了液压缸漏油污染研磨液的影响；对输球导环结构进行改进，采用料盘壳与料盘芯分离，料盘芯旋转，料盘壳不旋转，料盘壳开卸球缺口，实现自动卸球，降低了劳动强度。
介紹新型立式鋼毬研毬機3M7280的特點，其採用上盤減速電動機驅動絲槓加壓，消除瞭液壓缸漏油汙染研磨液的影響；對輸毬導環結構進行改進，採用料盤殼與料盤芯分離，料盤芯鏇轉，料盤殼不鏇轉，料盤殼開卸毬缺口，實現自動卸毬，降低瞭勞動彊度。

The characteristics of a new type vertical steel ball lapping machine 3M7280 is introduced.The upper is pressured with plate reducing motor drives screw,eliminating the pollution influence on lapping fluid from oil leakage of hydraulic cylinder.The structure of the guide ring for transporting balls is improved.The shell of feeding plate is sepa-rated from the core of feeding plate,the core of feeding plate is rotational,and the shell of feeding plate is rotational. By cutting a notch for unloading ball on the shell of feeding plate,automatic unloading ball is realized,reduced the la-bor intensity.
