2020 HERMLE C42 VERTICAL MACHINING CENTERS

Technical Description

The 2020 Hermle C42 is a 5-axis vertical machining center from Berthold Hermle AG, engineered for simultaneous 5-axis machining of complex medium-to-large workpieces across aerospace, medical, and precision manufacturing applications. 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 17.3-inch standard diameter and a rigid clamping surface option of 41.3 by 31.7 inches for heavy 3-axis operations. The spindle is rated at approximately 41.6 HP at 20% CDF with a standard maximum speed of 15,000 RPM, with high-speed options up to 56.3 HP and 42,000 RPM available depending on spindle configuration. The TNC 640 CNC control provides full simultaneous 5-axis contouring, high-speed machining cycles, advanced tool management, and thermal compensation, supporting the complex programs required for aerospace, medical implant, and precision die-mold manufacturing. Hermle's trunnion-table architecture ensures the workpiece remains centered within the rotational envelope, maximizing rigidity and positional accuracy during simultaneous 5-axis cuts. The machine's robust cast-iron construction, precision spindle bearing systems, and thermal management provisions maintain tight tolerances across extended production cycles. Automation provisions support pallet changers and robotic loading for unattended production. At approximately 29,762 pounds, the C42 represents Hermle's substantial mid-to-large-size 5-axis capability, combining the company's engineering precision with the structural mass required for demanding production applications.
