Under normal circumstances, the surface of 304L stainless steel belt is smooth and flat, but if there are ripples on the surface, many customers may not want to purchase this batch of goods. What is the reason for the ripples on the surface of 304L stainless steel belt? The following will be introduced by Xiaobian.
There are many reasons for the surface corrugation of 304L stainless 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 produces a certain vibration compared with the 304L stainless steel belt. The vibration includes forced vibration and self-excited vibration, resulting in straight wave ripples on the surface of the 304L stainless steel belt. This kind of ripple is deeper and the wave distance is wider.
When processing the 304L stainless steel belt, you can first apply a red oil film on the surface of the 304L stainless steel belt, and then adjust the moving speed of the worktable. Grinding wheel holder, so that the grinding wheel just touches the red oil film, and the vertical knife is quickly withdrawn at one time. At this time, there are "polygon" traces on the surface of the 304L stainless steel strip, and then measuring the side width of these polygons, the wave distance can be measured, and the wave frequency can be calculated.
In the process of surface processing of 304L stainless steel strip, due to elastic deformation with the machine tool during grinding, the intensity of self-excited vibration is increased, resulting in straight ripples on the surface of 304L stainless steel strip. Generally speaking, the corrugation is shallow, the density is high, and the corrugation frequency is usually about 300 times per second. However, as the stiffness of the machine tool increases, the friction force of the grinding wheel on the 304L stainless steel belt will also increase, resulting in an increase in the amplitude of self-excited vibration and a deepening of the corrugation depth. .
