油缸或汽缸体作为精密薄壁件,其加工有着自身的许多特点,本文将就缸体加工中所常遇到的几个问题,作一分析。一、粗镗中的排屑一般在缸体内孔的粗镗加工中,均采用单刃镗刀,(夹具及工件固定在中拖板上)此时,当工件较长(L/D>3)时,如果刀具参数或切削用量处理不当,将出现排屑困难。甚至由于切屑过份拥挤而使工件被抬离拖板。对于这种情况,首先,应查看切屑流
Cylinder or cylinder as a thin-walled precision parts, and its processing has many of its own characteristics, this article will be on the cylinder often encountered several problems for an analysis. First, the rough boring chip removal Generally in the cylinder bore rough boring process, are used single-blade boring knife, (fixture and workpiece fixed in the drag plate) at this time, when the workpiece is longer (L / D> 3), if the tool parameters or cutting the amount of improper handling, there will be chip evacuation difficulties. The work piece is lifted off the pallet even as the chips are overcrowded. In this case, first of all, you should check the chip flow
