Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Supfina spindles and motor spindles — the German manufacturer based in Wolfach in the Black Forest, the world largest supplier of superfinishing and double-disc grinding machines.
Supfina, the world largest supplier of superfinishing machines
TLDR: Supfina Grieshaber GmbH & Co. KG (Wolfach, Black Forest, Germany, formed in 1995 from the merger of two companies that had been cooperating since 1972) is the world largest supplier of superfinishing machines and accessories, with sites in Germany, the United States (since 1984) and China (since 2001).
Formed in 1995 from the merger of two companies that had been cooperating since 1972, Supfina Grieshaber has long-standing experience in stone and tape superfinishing, as well as in double-disc grinding and belt grinding. Based in Wolfach in the Black Forest, with sites in the United States since 1984 and in China since 2001, Supfina has established itself as the world largest supplier of superfinishing machines and accessories. Superfinishing is a material-removal process that differs from turning or conventional grinding through full surface contact between tool and workpiece, delivering unique surface properties: reduced roughness, bearing area increased beyond 90% and improved roundness and waviness microgeometry. The range covers superfinishing, flat finishing, double-disc grinding (Planet V series) and fine grinding (Spiro series).
A range of vertical and horizontal spindles for superfinishing and double-disc grinding
TLDR: Supfina machines in the Planet V series use a vertical spindle arrangement that delivers the best workpiece quality while reducing unit costs, with two powerful motors removing more than a millimetre of material in cycle times below one second.
On the double-disc grinding machines of the Planet V series, the vertical spindle arrangement gives the end customer the best final workpiece quality while reducing unit costs, with an extremely rigid frame able to grind steel, sintered metal, non-ferrous metal, plastic, ceramic and glass. Two powerful motors combined with this vertical configuration remove more than a millimetre of material in cycle times well below one second, with a patented navigation system (Tilt) for setting the gap between the wheels. On the fine grinding machines of the Spiro series, dedicated to functional surfaces requiring high-precision parallelism, reduced tool wear through minimised vibration at the machine frame is combined with a high-precision non-contact measuring system, with an F5 model designed specifically for small parts.
