Polished surfaces — perfect finish with ProfiRounder by Heesemann
Parts that require a sanded or brushed surface finish — often stainless steel or aluminum are often pre-sanded by sheet metal workers and covered with protective film. It only becomes difficult when the finish has to be on both sides, because laser cutting is ruled out when sheet metal is laminated on both sides. It is also often considered problematic when unusual material thicknesses require a finish, as delivery times may then be very long. As a result, many sheet metal workers also want to produce a surface finish with their continuous deburring machine.
Contact roller units for finish sanding
Since the vast majority of deburring machines have an unit with a contact roller, this is relatively easy to implement.
If the contact roller is converted to an appropriately fine abrasive, it is well suited for creating decorative sanded surfaces.
However, the finish is produced at significantly higher feed rates than is the case with deburring. While the feed rate during deburring is usually between 1.5 — 3 m/min, surface sanding takes place at 8 m/min and more.
As a result, the sheets that require a finish (often only a few % of total production) are passed through the machine a second time.
If the customer does not want to set up or sand in the same run, an additional broadband unit with contact roller is integrated into the machine as the last or penultimate unit.
Particularly fine surfaces with fleece brushes
Machines for the food industry and in commercial kitchen technology in particular require very fine surfaces with correspondingly low surface roughness levels. Fleece brushes are particularly suitable here, as they take the “tips” after sanding and refine the surface very efficiently in this way.
