You can still view this machine in our showroom in Bergeijk. Discover the innovatively developed SER1200 Multibrush finishing machine, designed with 4 processing stations and 17 individually controlled motors. The entire finishing machine can be operated via the HMI touchscreen, which is highly intuitive and ensures effortless operation. The display makes it easy to select different finishing programs, leading to high reproducibility of product quality and preventing operator setup errors. Thanks to the automatic height adjustment at the processing stations, consistency and precision are always ensured. At the first station of the finishing machine, burrs and irregularities are removed by a grinding unit, resulting in a flat, burr-free surface. After grinding, four oscillating combination brushes apply gentle pressure to the product, ensuring that all edges and holes of the flat-ground product are rounded, both around and inside. As the final processing step, the Multibrush round brushes provide perfect post-processing. The six brushes deliver a non-directional finish and round off the edges with a radius of 2+ mm, giving the product a high-quality and durable appearance. The SER1200 Multibrush finishing machine is also available in an XL version, featuring an additional fifth station. The fifth station consists of a second grinding unit, enabling a line finish on your product using a finer grinding belt or Scotch-Brite belt. The SER finishing machine utilizes a unique brush combination, exclusive to Q-Fin and marketed as: “The Ultimate Qombination”. This setup achieves a 2+ mm radius in a single pass. Gedpeyt Nm Eefx Af Ssub The SER1200 offers full ERP control and seamless integration into automated production processes — in short, a finishing machine that is ready for the future!

Guedpfxeyt Nhve Af Ssb The F200 XL is a 3-station machine and is standard equipped with the brush height tracking system developed by Q-Fin. In combination with the user-friendly button system, this ensures that both the setup and operation of the F200 are intuitive, resulting in the most operator-friendly machine available on the market. The machine features steplessly adjustable speeds for both the conveyor and the brush(es) and/or grinding head(s) as standard, making all manner of processes and finishing results achievable. You determine the desired finish yourself. The F200 XL can be equipped, as desired, with either a vacuum system (for non-ferrous metals, such as stainless steel and aluminium) or a magnet system (for ferrous metals). These systems ensure effective fixation of the workpieces on the conveyor table, allowing even small parts (from 10x10 mm) to be processed safely, effortlessly, and quickly. For good reason, we at Q-Fin advocate a narrow machine for small workpieces and a wider machine for larger ones. In many cases, the throughput speed of this machine is up to 5 times higher than comparable machines. You can view this machine in our showroom in Bergeijk.
