在搪床上加工大又长的孔时,由于加大搪刀杆直径受到限制,因而在切削过程中,容易产生刀杆刚性不良的现象。同时在比较长的一段搪削中,刀具也在不断的磨损。由于以上两种情况,要使大又长的孔在搪削后达到_7的光洁度和比较小的锥度是困难的。这里介绍一种结构简单的浮动搪磨杆,如附图所示,用它来加工能够解决上述存在的问题。浮动搪磨杆的使用方法:首先他被加工工件的孔搪到接近名义尺寸,留
In the boring machine processing large and long holes, due to increase the boring bar diameter is limited, so in the cutting process, easy to produce rigid arbor bad phenomenon. At the same time in a longer period of boring, the tool is constantly worn. Due to the above two situations, it is difficult to make the large and long holes reach a finish of 7 and a smaller taper after boring. Here is a simple structure of the floating rod, as shown in the figure, using it to process can solve the above problems. Floating honing rod method of use: First, he was processing the workpiece hole boring to close to the nominal size, leaving
