Highest grinding efficiency for the perfect coffee


What does a WMF coffee machine have in common with a Supfina fine grinding machine?
It is probably more than you might think.

Whether in the restaurant, café or even on the cruise ship - as one of the market leaders with 85 years of expertise in the field of professional coffee machines, the probability of being served a hot drink from a WMF machine is pretty high. At the same time, WMF, with its production in Germany, stands for not only the highest quality but also constant innovation with their own R&D. The heart of every fully automatic coffee machine is the grinder and especially the grinding discs. These not only pulverize the coffee beans but also crush them precisely in a coordinated ratio between coarser and finer particles. Achieving this requires a lot of experience, know-how, and a 100-meter-long production line at the parent plant in Geislingen an der Steige.

WMF entered into a partnership with Supfina to optimize its own grinding process. After joint process development and sample processing, the Wolfach-based solution provider delivered the Spiro F5 fine grinding system in November 2019. Since commissioning in February 2020, the combination of Spiro and the innovative grinding process has not only impressed with a reduction in grinding time to half but also with significantly lower wear. "Our experience shows that we have made exactly the right decision in working with Supfina," says Lutz Olbertz, Head of Production Turned Parts at WMF.

 Innovative process development for individual solutions
The innovative coffee mills are produced at the WMF plant in Geislingen, the company's headquarters located between Stuttgart and Ulm, Germany. Previously, the 100-meter-long production line also included a 30-square-meter grinding machine, which not only required a lot of space but also doubled the processing effort due to the one-sided machining of the workpieces. Despite a complicated workpiece with a large underside and a narrow upper edge, the Supfina team succeeded in presenting the machining in a two-sided process. In this way, the new Spiro F5 fine grinding system reduces machining to a single operation, halving grinding time and thus saving valuable working time and personnel costs. The new Spiro offers even more regarding process and productivity. As one of the world's leading suppliers in fine grinding, the right combination of tools and machines is one of Supfina's core competencies. Decades of experience and individual tuning help to significantly reduce wear here.

Everything from a single source
WMF is also delighted with the project process: "We particularly appreciate the pleasant, informal cooperation with the Supfina team," says Lutz Olbertz. In addition to the quality of the Supfina fine grinding systems, the fast delivery and the positioning as a process developer in the field of surface finishing contributed to the successful cooperation. Like WMF, Supfina also offers the entire process from development and conception to testing, sample processing and inspection in its measuring center, right through to a wide range of services from a single source. This reduces coordination effort, ensures quality, and enables fast delivery times.

The continuation of Spiro's success story
For Supfina, the successful cooperation with WMF represents a further step in the success story of the whole Spiro series of fine grinding machines. The Spiro F5, as the most economic machine of the series, stands out not only because of the highest demands on plane parallelism and dimensional accuracy but also because of its compact design and the resulting small footprint. If larger or unusual workpieces need to be machined, the Spiro series offers the right answers with the other models like the Spiro F7 and the largest model Spiro F12. These models can optionally make production even more efficient with fully automatic loading solutions through semi-autonomous production. In addition, Supfina offers modern service options to ensure long-term productivity and maximum machine availability for customers worldwide.
