About WWF
Winz Werkzeugmaschinen Fabrik GmbH (WWF), based in Seefeld (Brandenburg), develops and manufactures CNC-controlled cylindrical grinding machines for machining rolling bearing rings, rollers and other precision-ground rotationally symmetrical components. The portfolio comprises external cylindrical, internal cylindrical, universal internal cylindrical, centerless and roller grinding machines as well as special machines, including the rolling bearing grinding automatics AGU 50CNC and AGU 200CNC (machining range up to 200 mm, manual loading up to 400 mm) and the roller grinding machine AGR 50CNC with up to 7 axes for steel and ceramic rollers. In addition, WWF offers services such as CNC milling, CNC surface grinding (1500 × 600 mm), repair of mechanical assemblies, spare parts supply, software development and the development of measuring and testing equipment, such as the post-process measuring device WF 3000 and automatic sorting units with tolerance checking in the micron range. Reference customers come from the rolling bearing, automotive and railway industries, including Volkswagen, SKF, ZF and Mahle. The company operates internationally and regularly exhibits, among others, at GrindTec and Metalloobrabotka in Moscow.

Materials and Processes
Steel
Steel rollers (metallic rolling elements) are ground on the roller grinding machine AGR 50CNC.
Ceramics
Ceramic rollers (ceramic rolling elements) can also be machined with the AGR 50CNC.
Grinding processes (external/internal/centerless/universal/roller grinding)
Dressing methods via CNC radius dresser or diamond form roll enable various profile shapes of the ground surfaces.

Quality
The manufactured workpieces are inspected in the micron range (µm) using in-house developed measuring devices in a through-feed process; the post-process measuring device WF 3000 feeds the measured values back to the grinding machine control for automatic process data correction. No information is available on existing certifications.
