The HC-548EX features a high-rigidity, bridge-type monoblock structure with a minimized distance between the guide surface and spindle center. The high-rigidity bed with ideal rib distribution guarantees static positioning accuracy of ±0.000080" and ±0.000060" repeatability.

The HC-548EX is capable of a wide range (200 - 32,000 RPM) using a grease-packed 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-E40 holder achieves six times higher clamping force than a regular BT shank while the Air Balance Cylinder comes standard, reducing the load for ball screw and servo motor.

The HC-548EX 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.
