实踐証明:采用浮动鏜刀(图1、2)鏜孔有效地避免了由于車床主軸旋轉的不正确、床身导軌的磨損和扭曲所产生的椭圓度、錐度以及由于鏜刀的变形、震动对孔徑尺寸和表面光洁度的影响。我厂現已应用于鏜床、車床、立車、立銑等机床上来加工各种孔。消除了錐度、椭圓度誤差,提高了工件的质量。且由于刀杆尺寸事先可作精密調节,因此直徑公差能得到保証。即使操作水平較低,亦能做到图紙要求。 Practice has proved that: the use of floating boring tool (Figure 1, 2) boring effectively avoided due to the lathe spindle rotation is not correct, bed rail wear and distortion caused by the ovality, taper and boring tool deformation , The impact of vibration on the aperture size and surface finish. Our factory is now used in boring machine, lathe, vertical lathe, milling and other machine tools to process a variety of holes. Eliminate the taper, ovality error, improve the quality of the workpiece. And because the size of the shank can be adjusted beforehand, the diameter tolerance can be guaranteed. Even if the level of operation is low, can also do the drawing requirements.
