+GF+ MIKRON MILL X 400 U VERTICAL MACHINING CENTER

Technical Description

The +GF+ MIKRON MILL X 400 U is a high-precision 5-axis vertical machining center engineered for demanding applications in tool and mold making, aerospace, and medical component manufacturing. The machine features a travel envelope of 500 x 450 x 360 mm (19.68 x 17.72 x 14.17 inches) with exceptional rapid traverse capabilities of 100 m/min on the primary axes, delivering industry-leading speed and dynamics. The spindle operates at 42,000 RPM with 13.5 kW of power, paired with a 40-position automatic tool changer utilizing HSK-E40 tooling to maximize productivity and reduce changeover time. The MILL X 400 U incorporates sophisticated linear motor-driven direct-drive axes on all five axes (X, Y, Z, B, and C), eliminating ballscrew limitations and enabling exceptional accuracy and repeatability. The machine's B-axis tilting range spans ±110°, with unlimited C-axis rotation, providing complete multi-sided machining capability. A comprehensive temperature management system with independent cooling circuits for drives, machine body, spindle, and electronics ensures thermal stability and minimal tool center point drift, maintaining superior surface finish and dimensional accuracy. Control is handled by the Heidenhain TNC 640 CNC system, featuring intelligent software compensation and cutting condition monitoring with vibration and thermal tracking across all axes. The machine supports up to 18-pallet automation configurations, enabling extended unattended operation ideal for high-volume small parts production. Advanced features include high-precision ceramic hybrid bearings, sophisticated vibration control, and optional spindle coolant capability for drilling extremely small, deep holes efficiently.
