Every repair starts with a methodical diagnostic process: mechanical inspection, electrical checks, and system verification. Whether it's testing and cleaning linear scales on site, repairing control or servo issues on a Jones & Shipman, realigning a Kellenberger, or swapping a complete B axis on a Studer, we work from manufacturer specs and real field data — not guesswork.
Our technicians are based in the Northeast, Midwest, and Southeast, and we travel nationwide for service calls anywhere in North America.
