SIGMA CNC SDV-3219 VERTICAL MACHINING CENTER

Technical Description

The SIGMA SDV-3219 is a heavy-duty CNC double-column vertical machining center designed for large-scale production and precision manufacturing applications. This bridge-type machine features substantial work envelope dimensions with 126 inches of X-axis travel, 74.8 inches of Y-axis travel, and 39.3 inches of Z-axis travel, enabling the machining of large workpieces. The machine accommodates a maximum table load of 20,000 pounds on its 67-inch wide by 118-inch long work surface, equipped with eleven T-slots for secure workholding. The 40-position automatic tool changer with ISO 50 taper spindle operates at 6,000 RPM, providing efficient tool management and consistent cutting performance. All three axes utilize precision roller-type linear guideways, with the Z-axis supported by dual 85mm-wide THK-SRW series guideways positioned just 60mm from the spindle center, ensuring exceptional rigidity and repeatability. The machine is controlled by a FANUC 18i-MB CNC system, an advanced controller capable of complex multi-axis interpolation, offering flexibility for varied machining operations. The rigid double-column gantry design minimizes deflection during heavy cutting cycles, while the 80-inch column spacing accommodates large dies and molds. Equipped with coolant-through-spindle delivery and integrated chip conveyor systems, the SDV-3219 represents a robust platform for demanding production environments requiring precision and reliability.
