O.M.G. was established in the 1960s as a small workshop specialised in designing and manufacturing multispindle heads. At that time, production centred on three products: tapping spindles, adjustable joint multispindle heads and variable centre distance multispindle heads. Later on, in line with the evolution of the mechanical engineering industry, O.M.G. expanded and developed, taking part in the diffusion of new products with innovative and cutting-edge proposals for this research and production sector. The cutting-edge technologies employed inthe manufacturing processes and the use of new computerised methods resulted inthe O.M.G. brand name and image becoming widely known to small and large companies alike, an image sustained by a long series of advertising campaigns.
