为了提高镗孔工作的劳动生产率和质量,我们在六角车床上镗孔时,应用了科列索夫车刀几何形状的镗刀,镗刀上磨有消振倒稜。带有消振倒稜的车刀,是雷日科夫创造的。座用消振镗刀来镗孔,就消除了镗杆和刀头的振动,并可用大的切削用量来工作,因而大大提高了劳动生产率。图1是镗孔工作的情况。图中的工件是分三个步骤加工的: 1) 两次行程(正行程和反行程)中车削内孔2,并车削台口
In order to improve the labor productivity and quality of boring work, when boring on a hexagonal lathe, a boring cutter with the geometry of the Koleasov tool is used, and the boring tool is provided with an anti-vibration chamfer. With anti-vibration chamfer turning tool, is created by Ryzhkov. Block with boring vibration boring tool to boring, to eliminate the boring bar and head vibration, and can use a large amount of cutting work, thus greatly improving the productivity of labor. Figure 1 is boring work. The figure of the workpiece is processed in three steps: 1) two trips (positive stroke and anti-stroke) in the turning hole 2, and turning the mouth
