Under normal circumstances, the surface of stainless steel sheet ss 316 2b finish is relatively smooth and flat. If the surface is corrugated, many customers may not want to purchase this batch of goods. What causes the corrugation on the surface of the steel strip?
There are many reasons for the surface corrugation of the steel strip, one of the main reasons is the vibration of the grinding machine-steel-pipe-grinding wheel system during processing. During processing, the grinding wheel generates a certain vibration relative to the steel strip, among which the vibration includes forced vibration and self-excited vibration, resulting in straight wave ripples on the surface of the steel strip. This kind of ripple is relatively deep and the wave distance is relatively wide.
In the process of stainless steel sheet ss 316 2b finish, you can first apply a red oil film on the surface of the steel strip, and then adjust the moving speed of the worktable, so that the moving distance of the worktable is slightly equal to three times the rotation width of the grinding wheel when the workpiece is rotated. Second, move the grinding wheel frame so that the grinding wheel just touches the red oil film, and the vertical knife is quickly withdrawn at one time. At this time, we can find that there are "polygon" traces on the surface of the steel belt, and then measure the side width of these polygons. The wave distance can be measured and the wave frequency calculated.
During the surface processing of stainless steel sheet ss 316 2b finish, because the steel strip will elastically deform with the machine tool during grinding, the intensity of self-excited vibration will increase, resulting in straight corrugations on the surface of the steel strip. Generally, the corrugation is shallow and the density The frequency of the corrugation is usually about 300 times per second, but as the stiffness of the machine tool increases, the frictional force of the grinding wheel on the steel belt will also increase, resulting in an increase in the amplitude of the self-excited vibration and deepening the depth of the corrugation.
