Founded in 1949, Franke GmbH develops and produces wire roller bearings, turning systems, and linear systems. Customers from medical technology, renewable energies, and aerospace technology trust in the innovative and high-quality solutions of the technology leader.
To meet the quality requirements, Franke relies on six machining centers from DMG Mori for mechanical processing. With the global spread of the COVID-19 virus and increasing demand for medical technology components, Franke ordered two additional DMC 125 FD duoBLOCK.
High-end special bearings with integrated drives for CT xcanners, bearings for ceiling lights in intensive care units, and special bearings for medical centrifuges and laboratory devices are just a few examples of what Franke manufactures for well-known medtech OEMs. The company’s share of medical technology sales rose from 35% to more than 40% in 2020.
µ-precise production of bearing components
Franke has been manufacturing with machining centers from DMG MORI since 2008. Its machine park includes a DMU 210 FD and the DMC 80 FD duoBLOCK, DMC 125 FD duoBLOCK, and DMC 160 FD duoBLOCK equipped with a pallet changer. All machines have an accuracy package.
The duoBLOCK models in particular play a decisive role for Oliver Schröder, authorized representative and head of purchasing and materials management: “Milling and turning in one clamping combined with the automatic pallet changer offer us the optimal package for processing highly complex housing parts for special bearings from 300mm to 2,000mm. The accuracy is in the µ range.”
One of the two recently ordered DMC 125 FD duoBLOCK also has the DMG MORI technology cycle gearSKIVING in order to be able to manufacture straight and oblique external and internal gears in-house using conical gear skiving tools in the future. This can reduce both costs and lead times.
