German Machine Tools of America, founded in 1991 as the U.S. subsidiary of Profilator GmbH in Wuppertal, Germany and based in Ann Arbor, Michigan, today represents various lines of German machine tools and metal fabricating equipment, including gear cutting and honing, laser welding, surface grinding and deburring machines, wheelset presses, straightening presses, rail track presses, multi-spindle lathes, multi-station vertical turning machinery and more.

With over 400 machines installed in North America, German Machine Tools of America (GMTA) is a market force in precision workpiece and specialty markets such as gear manufacturing, wherever accuracy is a must, regardless of the operation or end product produced.

Standing behind every machine we sell is the service and application engineering departments of GMTA, a recognized leader in supplying machining and fabricating equipment solutions to major American markets, from automotive to iron/steel, gear manufacturing to railroad, heavy equipment to medical. The equipment is supported by the offices located in Ann Arbor, Michigan and Queretaro, Mexico.

Engineering the right solution to meet the application is often just the beginning. Owing to the substantial capital investment made by our customers, we remain constantly in tune with budget requirements and machine utilization, today and into the future.

GMTA seeks to become your partner in supplying high-quality machines. We'll prove our value, from the first contact through commissioning and after sale-service.

During 2012, the decision was made to change the name of our company from American Wera to German Machine Tools of America (GMTA), reflecting the full range of high-quality, German-built machine tools we represent. The new name was officially introduced and is now in full circulation throughout our North American sphere of responsibility.
