The innovation that accepts temperature changes

High accuracy can be achieved in normal factory environments

The machining accuracy of workpiece changes significantly due to the ambient temperatures around the machine, heat generated by the machine, and heat generated in machining.
The Thermo-Friendly Concept is a unique concept to “accepting” such temperature changes so that high accuracy can be achieved in normal factory environments with no special measures taken by the user.

High accuracy

The whole machine is designed to achieve high accuracy.
Outstanding dimensional stability enables stable machining of high-accuracy parts
and stable operation over long hours

Thermo-Friendly Concept is Okuma Intelligent Technology intended to achieve amazing machine accuracy with unique structual design and thermal deformation control technology.
It eliminates the need for cumbersome dimensional compensation and warm-up and demonstrates outstanding dimensional stability in long-term continuous machining, multitasking machine, front and back side machining with a sub spindle, and Y-axis machining.
