Legacy Product Support

LegacyProduct Support290x215

Protecting your investment in Mitsubishi Electric products is one of our top priorities. It is why we continue to support our products since 1974. You can trust our service experts to help you get the most from your investment, no matter the age, and to keep your operations running smoothly and efficiently.

Over time, your product may not perform as well as it did on day one. Maybe your control takes a long time to power on in the morning or locks up in the afternoon, perhaps your spindle speed is becoming erratic or you are experiencing mis-position on one of your axes. We are here to help bring your CNC, servo drive, or spindle drive as close to day one performance as possible. Below you will find some of the checks and replacements we will perform on your legacy equipment. We will also inform you if the equipment should be sent in for cleaning and inspection and make recommendations if any components are operating below standards. We will also inform you of any retrofit options for your products.
