Chiron MC 331 VERTICAL MACHINING CENTER

Technical Description

The Chiron MC 331 Vertical Machining Center is a high-performance CNC milling machine designed for precision vertical machining applications. It features a sturdy worktable measuring 27.5" x 12.5", with an optional expandable size up to 43.3" x 177", and supports a maximum workpiece weight of 1,764 lbs. The machine is equipped with dual vertical main spindles using HSK-A63 taper, delivering speeds up to 10,000 RPM standard and optionally 12,000 RPM, powered by 67 hp motors rated for 30 minutes. The tool carrier is an automatic tool changer (ATC) supporting up to 48 tools standard and 60 tools optionally, with a rapid tool change time of 2.4 seconds. The MC 331 operates with a 3-axis configuration, with an optional 4-axis upgrade, featuring travels of 20.47" (X), 14.17" (Y), and 15.7" (Z), expandable on the X and Y axes, and rapid traverse rates up to 2,633 inches per minute. The table includes a standard indexed rotary table support, with a rotary table option for enhanced multi-axis machining flexibility, offering A and B axes motion with 180° and 360° respectively. The machine is suitable for heavy and complex workpieces requiring precision, rigidity, and speed, making it ideal for industries demanding high machining productivity and versatility. It offers a robust build with high thermal stability and accuracy to meet demanding production environments. The advanced spindle system and tooling options optimize cycle times and maintain operational efficiency.
