This machine works on the welding cord area, grinding where web and flange are welded together. The cleaning of the plate is carried out by an abrasive wheel on the top, installed on a manual slide, allowing the operator to work on axis or axis-off on the plate, removing any rust or oxidation.
The web’s cleaning is done through the use of 3 grinding wheels at the same time. The upper and lower grinding wheels are used to clean the surfaces, up to a width of 40 mm, starting from the edge of the sheet.
Meanwhile, the front grinding wheel cleans the thickness of the plate, where there are cutting residues, as their removal is necessary to have a good contact between web and plate, during the welding process. The advantage of this machine is that you can clean three surfaces in one single pass.
The use of a WFTB unit saves hundreds of hours of manual work and optimizes the productivity of subsequent welding processes, making the sheets quickly available.
