The Herford-based family business PREWI Schneidwerkzeuge GmbH develops tools for the wood and furniture industry. The company supplies its customers across the world with milling cutters, drills and circular saws tipped with carbide or diamond. To manufacture these, PREWI uses around 30 sharpening machines from VOLLMER (based in Biberach). The Swabian specialist in grinding and eroding machines delivered the first eroding machine to East Westphalia at the end of the 1980s. PREWI opted for sharpening technology from VOLLMER only recently – a QXD 250 disc erosion machine.
"For many years, we have been placing our trust in VOLLMER's sharpening expertise when it comes to eroding diamond-tipped rotary tools and circular saws," says Helmut Prekwinkel, founder and CEO of PREWI Schneidwerkzeuge GmbH. "With the new QXD 250 disc erosion machine, we want to expand our range of diamond-tipped milling cutters and drills so that we can respond much more precisely, quickly and flexibly to customer requirements."
Tool manufacturer for over 50 years
Helmut Prekwinkel founded his company in 1962 and PREWI, with its 45 employees, has now become one of the leading suppliers of chipping tools for manufacturers of furniture, doors and laminate/parquet flooring. Whether special tools or high volumes of cutting tools, this medium-sized company offers the whole range for the precise and flexible cutting of wood and composites. From advice about implementation and manufacturing, through to training and after-sales service – customers can get everything from a single source at PREWI.
Goldener Meisterbrief for an innovative spirit
On an operating surface of 18,000 square metres, PREWI produces cutting tools, machining units, exhaust ventilation systems, pressure pads and landing skids, as well as measuring devices for all areas of the wood processing industry. The toolmaker is a pioneer in the use of PCD (polycrystalline diamond) for rotary tools: In 1984, the first PCD folding chipper was produced, which door manufacturers use to make door frames, among other things. PREWI also leads the way when it comes to using MCD (monocrystalline diamond) and for four years, was the sole provider of MCD tools in the market. Helmut Prekwinkel was recently honoured with the Goldener Meisterbrief (gold master craftsman's diploma) for the commitment he has shown over many years as an innovator in tool technology.
"We were one of the first manufacturers to bring PCD-tipped tools to the market in order to efficiently machine highly abrasive materials," says Helmut Prekwinkel. "To precisely sharpen our diamond tools to a high standard of quality, we have put our trust in VOLLMER's eroding machines for many decades now."
