Stainless steel perforated sheet is produced by a numerical control punching machine according to a customized mold. The burrs on the mesh surface of stainless steel perforated sheet directly affect product quality. So how are the burrs on stainless steel perforated sheet produced?
The burrs on stainless steel perforated sheet are mostly caused by the unreasonable gap of the mold. The mold for producing stainless steel perforated sheet consists of upper and lower parts. The upper part is installed with the punch of the stainless steel perforated sheet, and the lower part corresponds to the hole of the punch on the upper part. Under normal circumstances, the hole on the lower part is slightly larger than the punch on the upper part, and the gap between the upper and lower parts is determined according to the thickness of the plate material. If the gap between the upper and lower parts is too large, it will cause the back side of the stainless steel perforated sheet to produce burrs.
In addition, the wear of the punch over a long period of time will also cause burrs on the back side of the stainless steel perforated sheet.
