About Arno Barthelmes Zella-Mehlis
Arno Barthelmes Zella-Mehlis GmbH is a family-owned CNC contract manufacturer based in Zella-Mehlis in Thuringia with around 35 employees. The company produces individual parts, prototypes as well as zero, small and medium series, custom-made to drawing or 3D model. Manufacturing includes CNC milling (3-axis and simultaneous 5-axis HSC milling), CNC turning, CNC drilling as well as surface, disc and cylindrical grinding, through to assembly and laser marking. In addition, components are captured by 3D measurement and additively manufactured from metal powder in a multi-laser system, for example for the rapid repair of spare parts. Materials processed include aluminium and its alloys, construction and alloy steels, stainless steel, brass, copper as well as plastics such as POM and PE. Customers come from medical technology, aerospace, mechanical and plant engineering, the automotive supply industry, lighting and laser technology as well as Deutsche Bahn, mining and boiler construction.
