About us
Mechanische Fertigung Peter Korb GmbH is a CNC contract manufacturer based in Dachau-Pellheim that produces precision parts according to customer specifications, drawings or models. Its main field of activity is components for the precision mechanics industry and mechanical engineering; the company specializes in single-part and small-batch production with high quality requirements, and through cooperation partners it can also supply up to large series. In-house capabilities include CNC milling up to 5 axes (travel range up to 1680 x 860 x 760 mm), CNC turning up to Ø350 mm with bar feeders up to Ø80 mm, conventional turning up to Ø530 mm, surface grinding, and material cutting on two bandsaw machines. Programming is done using the CAD-CAM system TopSolid (among others stp, igs, dxf). Heat treatments (case hardening, nitriding, induction hardening) and surface treatments (electroplating, anodizing, bluing) are carried out with long-standing partner companies. Production serves mechanical engineering, plant engineering, medical technology, electrical engineering, tool and die making, as well as research and development.
