镗杆机由于结构简单,制造方便,而又最适于大孔的加工,所以在许多工厂中获得应用。但是,目前在使用过程中也暴露了一些不足之处,如工件装卸较麻烦,轴向快速退刀不易于实现,从而大大地增加了非工作时间。大家都知道,镗杆机工作时,主轴(镗杆)本身只有转动而没有移动。它的轴向走刀是由主轴通过一套差动齿轮而将运动传给走刀丝杆,使它除跟主轴转动外,本身还相对于主轴转动,从而带动了套在主轴上的轴向刀架作走刀运动(见图)。通常,走刀完毕后只需将电 Boring machine due to simple structure, easy to manufacture, but most suitable for the processing of large holes, so in many factories access to applications. However, at present, some shortcomings have also been exposed during use, such as troublesome loading and unloading of workpieces, rapid retraction in axial directions is not easy to achieve, and the non-working time is greatly increased. As we all know, boring bar machine work, the spindle (boring bar) itself only rotate without moving. Its axial pass through the spindle by a set of differential gear and pass the motion to take the lead screw, so that in addition to rotating with the spindle, itself also relative to the spindle rotation, which led to the sleeve set in the axial Tool holder for the knife movement (see photo). Normally, you only need to turn the electricity on when you’re done
