Problem solver even for tricky cases

HaGeForm was founded in 1992 as a branch of a company from North Rhine-Westphalia in Lößnitz in the Erzgebirge. Following a change of ownership, the company established a new site in Stollberg in Saxony. In 2012, Sebastian Baier and his father took over the business together. Since 2018, he has managed HaGeForm Sachsen with its 15 employees as Technical Managing Director along with his sister Stefanie Baier, who serves as Commercial Managing Director.

Around 90 percent of their customers are located within a radius of 50 kilometres. This proximity is a big plus for the manufacturer, since fast delivery times are becoming more and more crucial. „We do a lot of things on demand,“ explains Baier. „We usually bring the parts to the customer by car, so there are no long haulage routes.“ In addition to parts for the Die & Mould sector, components for general machining and all sorts of other industries are being produced in Stollberg as well.
 

For some parts, the transition to complete machining was successful. For example, a fineblanking die made of powder-metallurgical metal used to be removed from the machine after milling for subsequent vertical erosion of small corner radii with shoulders. „We couldn‘t imagine doing it any other way,“ admits Seibt. „Now we can co­ver all that with milling, which is quite an innovation. “ In the meantime, the OptiMill-3D-HF-Hardened high-feed milling cutter and the OptiMill-3D-BN-Hardened ball nose milling cutter are also regularly used for hard machining at HaGeForm. The trochoidal milling cutter OptiMill-Tro-Hardened is used for two-dimensional roughing directly in the hard material. This allows full utilisation of the cutting edge length, which always corresponds to 3xD with this tool, for machining material hardnesses up to 65 HRC without any problems and guarantees maximum cost-effectiveness through the highest stock removal rates in the shortest possible time.

MAPAL has come to be appreciated as a problem solver. For very complex titanium parts, a possible machining strategy was mulled over for a long time. In the end, MAPAL was called. Felix Wendler came to Stollberg with the right milling cutters for titanium and also stayed until a suitable programme for the complicated part was created and the machining was up and running. Complex shapes combined with special materials always place new demands on the manufacturers. „We receive really great support from MAPAL in this respect, “ praises Maik Seibt. „When we encounter problems, all it often takes is a phone call. It‘s good to have a competent contact person to ask.“
 

Auch dieses PKD-Werkzeug konnte bei HaGeForm überzeugen. Es erzeugte absolut glatte Oberflächen und sah nach einigen Einsätzen noch aus wie neu, womit sich bereits lange Standwege andeuteten. Felix Wendler sieht Marktvorteile für die sächsischen Fertiger: „Nur sehr wenige Unternehmen sind derzeit in der Lage, Hartmetall prozesssicher und vor allem wirtschaftlich zu zerspanen, darin ist HaGeForm wirklich gut.“ 

Die Partnerschaft soll fortgesetzt werden. Als nächstes stehen Gewindefräser für gehärtetes Material an, denn HaGeForm hatte sich darüber beklagt, dass die Werkzeuge des bisherigen Lieferanten nicht ausreichend lange halten. Anspruch von MAPAL ist es nun, mit einem neu entwickelten Fräser möglichst viele Gewinde prozesssicher bei Materialhärten von bis zu 65 HRC einzubringen.
