Sigma SDV-4219 VERTICAL MACHINING CENTER

Technical Description

The Sigma SDV-4219 is a high-performance vertical machining center designed for heavy-duty and precision applications. It features a robust 3-axis CNC configuration with generous travel distances of 165.3" (X), 74.8" (Y), and 39.3" (Z), supporting rapid traverse rates of 590 ipm across all axes for efficient material removal and reduced cycle times. The machine is equipped with a vertical spindle utilizing a #50 taper, capable of reaching up to 6,000 RPM and delivering 35 HP (30-minute rating) for demanding machining tasks. The large worktable measures 157" x 66.9", accommodating workpieces weighing up to 28,600 lbs, making it suitable for large-scale industrial components. Tool management is handled by a 40-pocket automatic tool changer (expandable to 60 tools), ensuring fast and reliable tool changes. The SDV-4219’s rigid double-column structure and roller-type linear guideways provide exceptional stability, accuracy, and vibration resistance during both heavy and fine cutting operations. Its design supports high-precision machining with consistent surface finish, ideal for industries requiring large-format milling and high material removal rates.
