Complete machining of machine and gear parts in the ultra-precision range, cubic up to 1500 mm, toleranced in the micron range.

Hemminger Maschinenbau GmbH
Ostfildern (DE)New on Amplifa
Contract manufacturing in the ultra-precision range since 1963
Hemminger Maschinenbau GmbH, based in Ostfildern near Stuttgart, is a family-run contract manufacturer for CNC machining and has stood for precision in metalworking since 1963. The company manufactures and machines machine and gear parts such as cylinder heads, slides, housings, spindle housings and turret heads to customer specifications — from prototypes and single parts to small and medium series. Complete machining is carried out in the ultra-precision range using CNC machining centres, boring mills and jig boring machines, cubically up to 1500 mm, with tolerances in the micron range. Machined materials include castings made of aluminium cast alloys, grey cast iron and spheroidal graphite cast iron (ductile iron), as well as workpieces made of steel, stainless steel, aluminium, non-ferrous metals and plastics. In addition, the company manufactures production and clamping fixtures, assembles components and offers consulting services for design and production. Customers come from mechanical engineering, special machinery construction, the automotive industry, toolmaking and aerospace engineering; deliveries are made to the German-speaking region (Germany, Austria, Switzerland).
