在硬质合金锯片四周消除应力的孔内,镶入软铜塞能消除锯片的振动,并能产生许多良好的效果。硬质合金锯片通常具有供膨胀用的切口,它与消除应力的孔相通。通过将铜塞满孔,消除了孔所发出的极高的噪音,同时也抑制了由于膨胀切口和个别刀齿冲击工件所产生的振动。试验表明,振动的降低能获得优良的表面光洁度,从而 Placing a soft copper plug in the stress-relieved hole around the carbide saw blade eliminates the saw blade vibration and produces many good results. Carbide saw blades typically have a cutout for expansion that communicates with a stress-relief hole. By filling the plug with holes, the extremely high noise emitted by the holes is eliminated, while the vibrations generated by the impact of the swaging cut and the individual tooling on the workpiece are also suppressed. Experiments show that the reduction of vibration can get good surface finish, thus
