Milford, Ohio, USA is the headquarters of the subsidiary ECOROLL company, which was established in 2004. The strongest industrial sectors in the Midwest include mechanical and equipment engineering, the automotive industry, and aerospace technology. For example, in the automotive industry, crankshafts are tightly rolled, while in the aviation field, aircraft rims and engine components are machined with ECOROLL tools. ECOROLL tools and machines refine metal surfaces by forming a surface layer. One or more rollers installed in the tool are pressed against the surface of the component so that the material flows and levels out existing roughness. Depending on the machining process, the tool, the workpiece, or both can rotate. This machining smooths the surface and extends the service life of the workpiece. Depending on the application, the process is called smoothing (smoothing the surface) or burnishing (extending service life).
