About Erhard Bauer GmbH
Erhard Bauer GmbH is a family-owned metal processing company founded in 1983, headquartered in Bad Ditzenbach/Gosbach at the foot of the Swabian Alb. Its core competence is CNC turning technology: chuck, bar and long turning (Swiss-Turn) as well as polygon and automatic lathe parts. This is complemented by CNC milling in 3, 4 and 5 axes, EDM wire cutting, cylindrical and surface grinding, honing, planar lapping, and TIG and MIG welding of steel, stainless steel and aluminium. Materials machined include steel, stainless steel, aluminium and titanium. On more than 600 m² of production space, 10 employees manufacture complex products in small and medium series as well as prototypes and special parts from a lot size of 1, mostly to customer drawings. Customers come from mechanical engineering, hydraulics and valve technology, standard parts, apparatus and plant engineering, and general precision mechanics. The entire value chain — from material consulting through CAD/CAM to cleaning, packaging and quality assurance — takes place in-house at the single site.
