JJ Automation can retrofit obsolete CNC's, i.e. machine tool mills, grinders, lathes and routers with FANUC, SIEMENS, MITSUBISHI CNC controllers. Machine tools represent significant capital investments and must maintain their viability for many years. Keeping them updated with the latest control technologies via CNC retrofit is one way to do that successfully today. A CNC retrofit includes upgrades to the CNC, the servo motors and drives, the spindle motor and drives, and a portion of the associated wiring and related electromechanical components. Unlike rebuilding and remanufacturing, a CNC retrofit does not include any major repairs to the machine mechanics, so the machine itself is otherwise still in working condition.

Our scope of work for machine retrofittment
