2021 HERMLE C 42 U MT VERTICAL MACHINING CENTER

Technical Description

The 2021 Hermle C 42 U MT is a 5-axis vertical machining center with integrated turning capability, manufactured by Berthold Hermle AG. The MT (Mill-Turn) designation indicates a primary milling spindle complemented by a high-torque turning spindle in the rotary table, enabling combined milling and turning operations in a single workholding setup—reducing setups and improving dimensional accuracy for complex rotational and prismatic components. The machine provides a 31.5-inch X-axis, 31.5-inch Y-axis, and 21.7-inch Z-axis work envelope, with a swiveling rotary table of 29.5 inches diameter suitable for medium-to-large mill-turn workpieces. The milling spindle reaches 18,000 RPM with approximately 56 HP at 20% CDF, providing high-speed capability for milling, drilling, and contouring in aluminum, steel, titanium, and Inconel. The Heidenhain TNC 640 CNC control supports full simultaneous 5-axis contouring and integrated turning cycles, with advanced tool management and graphical simulation to support complex combined mill-turn programs. Hermle's trunnion-table architecture, combined with the turning table's high-torque capability, delivers the rigidity and accuracy required for aerospace, medical implant, and precision engineering components. The cast-iron structure, precision spindle bearings, and thermal compensation systems maintain tight tolerances during extended machining cycles. At approximately 29,762 pounds, the C 42 U MT represents a substantial, production-capable mill-turn platform reflecting Hermle's highest standards of precision engineering.
