MC-HC-878View All Mitsubishi Corporation Machinery Systems
The HC-878's high-rigidity, bridge-type monoblock structure allows high-speed, high-precision machining, while the minimized distance between guide surface and spindle center provides greater stability. The high-rigidity bed with ideal rib distribution guarantees static positioning accuracy of ±0.000078” and ±0.000039” repeatability.
The HC-878 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. New HSK-E40 holder achieves six times higher clamping force than a regular BT shank while Dual Balance Cylinders reduce the load for the ball screw and servo motor.
The HC-878 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.
