Okuma’s CNC Exchange Division makes available replacement/exchange of electronic units usually in less than one business day, as most of the time we are able to send you a unit before receiving your return item. Because Okuma designs and builds our machines and controls, you get diagnosis and repair from a single source. That gets you back up and running quickly and efficiently. All repairs are performed by certified Okuma personnel using OEM replacement parts and are guaranteed for 12 months, saving you up to 50% of the cost of new parts. Okuma Board & Drive Exchange has more than 3,000 units in stock and supports technology for every Okuma machine ever produced.
