镐筒深孔钻主要用于加工圆柱零件偏心深孔,采用外排屑方式。加工过程是手动进给与退刀。对于加工不同直径,不同偏心工件深孔,可换分度旋转头里零件偏心轴来进行。过去镐筒在摇臂钻床加工,工件固定不动,经常发生深孔与轴线不平行,并且有时钻漏。自采用此钻床后,消除了上述现象,保证了产品质量;分度准确,辅助时间缩短,有利于提高劳动生产率;操作简单方便,适用于成批生产。
Drum tube deep hole drilling is mainly used for processing cylindrical parts eccentric deep hole, the use of external chip removal methods. Processing is manual feed and retraction. For the processing of different diameters, different eccentric workpiece deep hole, you can change the indexing eccentric part of the rotating head to carry out. In the past, the barrel was processed in a radial drilling machine and the workpiece was stationary. It was not uncommon for the deep holes to be parallel to the axis and sometimes to leak. Since the adoption of this drilling machine, eliminating the above-mentioned phenomena, to ensure product quality; accurate indexing, auxiliary time is shortened, help to improve labor productivity; simple and convenient operation, suitable for mass production.
