The Highest Precision and Productivity for Graphite and Hard Milling
The HC-548EX features a high rigidity, bridge-type monoblock structure with minimized distance between guide surface and spindle center. The high rigidity bed with ideal rib distribution has been designed by computer analysis with a guaranteed 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 can be done by dry or semi-dry oil-mist systems. New HSK-E40 holder achieves six times higher clamping force than a regular BT shank while a Air Balance Cylinder comes standard, reducing load for ball screw and servo motor.
The HC-548EX features a Fanuc 31i-A5 Super High-Speed Processor and Al Contour Control II – A “NANO CNC System” with Intelligent Velocity Control, NANO Interpolation and NANO Smoothing. The look ahead has been expanded to 1,000 blocks.
