Wet sanding machine optimally rounds edges

Lissmac SMW 545 gives metal parts a beautiful appearance
“Good tools are half the work”, as the saying goes. For BVS Blechtechnik as a highly automated production company, this means in a figurative sense: without efficient technology, no process optimization. The recently installed Lissmac SMW 545 wet sanding machine improves work performance in the area of surface sanding. The system, which consists of four units, rounds effectively so that internal and external contours are deburred simultaneously.

The new Lissmac replaces the previous Ernst sanding machine and is a big hit with the specialists in the sanding department. “We achieve a much better rounding of all edges with the Lissmac,” Roland Steiner, Head of Technology, is convinced.

BVS received a system from the manufacturer Lissmac that was specially put together for their needs – it is only available at BVS in this modular order. The Lissmac is used for rounding and surface grinding to give laser-cut workpieces with a clearance height of up to 120 mm the desired design finish. The machine is designed in such a way that it pre-grinds with the first unit using wide belt rollers, followed by rounding with cup brushes. Fine sanding takes place in the third unit, and finally secondary burrs are removed with a non-woven roller brush and finally dried.

The operators measure the material thickness before inserting the metal parts and program the units to be run through based on the desired surface standard. For recurring orders, you can quickly call up the saved data again.

Incidentally, the Lissmac only works in a “3-pack”. An external ultra-fine filter system, the Micron filter system, is connected to the wet grinding machine. It ensures that the process water is extremely clean and that abrasion is separated from the cooling lubricant. The third component is the UV system, which kills bacteria in the rinse water. Thanks to the antibacterial effect of the UV rays, no biocides need to be used, so there are no chemicals in the waste water and at the same time the operators are not exposed to any chemicals.

The new wet grinding machine is ideal for the wide range of materials to be processed, such as aluminum, steel or stainless steel, and complements the grinding process step as the sixth machine. BVS customers can rely on the best results, because optics play a major role in visible parts for industrial products.
