Matters needing attention when using laser to cut medium and heavy JIS G3101 SS400 steel plate

In the process of heavy JIS G3101 SS400 steel plate cutting, why the cut edges need to be grinded? That is to prepare for the next process and improve the aesthetics of the product. In addition, by grinding operation, the oxide scale and burr on the workpiece can also be removed, so that cutting medium and heavy JIS G3101 SS400 steel plate quality can be improved.

How much is the upper limit of steel plate thickness when laser cutting is used in medium and heavy JIS G3101 SS400 steel plate cutting?
Medium and heavy JIS G3101 SS400 steel plate cutting needs feeding material and marking first, then cutting. In the process of medium and heavy JIS G3101 SS400 steel plate cutting, the upper limit of plate thickness is 20mm if laser cutting is used. If the thickness of JIS G3101 SS400 steel plate is more than 20mm, flame cutting is used, while plasma cutting is used for thin JIS G3101 SS400 steel plate. In addition. Laser cutting can be used if the cutting requirements are relatively high.
