The MEGA SS-400's high-rigidity, bridge-type monoblock structure allows for high-speed, high-precision machining with minimized distance between the guide surface and spindle center, providing greater stability.

The high-rigidity bed with ideal rib distribution guarantees static positioning accuracy of ±0.000059" and ±0.000012" repeatability. The MEGA SS-400 is capable of a wide range (3,000 - 40,000 RPM) using an oil-mist lubricated spindle and a long-life AC motor. High-speed direct hard milling is possible via dry or semi-dry oil-mist systems.

The new HSK-E25 holder achieves six times higher clamping force than a regular BT shank. The MEGA SS-400 features a Fanuc 31i-B5 Super High-Speed Processor and Al Contour Control II – a "NANO CNC System" with Intelligent Velocity Control, NANO Interpolation and NANO Smoothing.
