龙门刨床在加工过程中，每当工作台向前移动之前，都要完成刀具进给。通常的进给控制方法多为机械式的，如Ａ系列龙门刨床采用了带涨紧环的进刀机构和用不同齿数的圆盘及进刀继电器组成的进刀机构。它们的缺点是机械零件易磨损，因而增大进刀控制误差。为了改善龙门刨床的...
Planer in the processing process, whenever the table moves forward, to complete the tool feed. The usual feed control methods are mostly mechanical. For example, the A series planer adopts the feed mechanism with the tension ring and the feed mechanism with different numbers of disks and feed-in relays. Their disadvantage is the easy wear and tear of mechanical parts, thereby increasing feed error control. In order to improve the planer ...
