About P.Konzett Verzahnungs- und Präzisionstechnik
P.Konzett Verzahnungs- und Präzisionstechnik GmbH is a contract manufacturer specializing in grinding and gear technology, located in Ravensburg-Schmalegg. The company manufactures externally, straight- and helically geared gear parts using profile gear grinding in a single-piece process, exclusively utilizing CBN grinding wheels. The scope of services also includes external and internal cylindrical grinding on CNC universal grinding machines, where external and internal diameters can be processed under tension, and flat grinding in climate-controlled production for dimensional and geometric accuracy. The company primarily processes difficult-to-machine, wear-resistant steel alloys as required in gear technology. Parallel to production, contract measurements are performed with test protocols, including gear testing, roughness and contour measurements, bevel gear as well as form and runout measurements, and thermal conductivity tests via Type B nitriding. P.Konzett Verzahnungs- und Präzisionstechnik GmbH has been certified to DIN ISO 9001:2015 since July 2021 and serves customers in gear technology.
