About Völcker & Wiens
Völcker & Wiens GbR is a Bielefeld-based company specializing in metalworking contract manufacturing. Since 2005, the company has produced turned and milled parts as single parts, prototypes, custom-made items, and small and large series. Production takes place on modern CNC machine tools, including two large-format ZAYER milling machines with travel paths up to 12,000 mm, several 5-axis machining centers from WEMAS, and a surface grinding machine for parts up to 3,000 mm in length. Focus areas include machine components, tools, plates, and wear parts for mechanical engineering as well as tool and die making. Around 30 employees produce on a production floor of 3,000 m² near the A2 autobahn. The company is certified to EN ISO 9001:2015 and completes orders on time with trained skilled workers in its own machine park.
