SOUTHWESTERN INDUSTRIES TRAK VMC12SI VERTICAL MACHINING CENTER

This vertical spindle CNC machining center features a robust 3-axis configuration with extensive travel capabilities: 50 inches on the X-axis, 27.5 inches on the Y-axis, and 25 inches on the Z-axis, providing substantial machining capacity for medium to large workpieces. The machine is equipped with a CAT 40 spindle taper and delivers impressive spindle performance with a maximum speed of 12,000 RPM, powered by a 67-horsepower motor system that ensures consistent cutting force across diverse material applications. The work table dimensions of 51.2 inches length by 23.6 inches width accommodate various part sizes, while the automatic tool changer (ATC) with 25-tool capacity enables rapid tool changes and unattended production runs, significantly improving throughput and reducing cycle times. The machine is controlled by the advanced SINUMERIK ONE CNC system, featuring a 15-inch multi-touch interface and integrated PPU 1740 processing unit that combines CNC, HMI, and PLC functions for seamless operation and programming. This control system delivers 1.5ms block processing and 500-block look-ahead for high-speed machining capabilities, along with conversational programming options and 3D collision avoidance simulation. The SINUMERIK ONE architecture supports up to 12 linear interpolating axes and universal NURBS interpolation, enabling complex 5-axis operations when configured with rotary tables. This combination of substantial work envelope, powerful spindle, high-capacity tool magazine, and sophisticated CNC control makes the machine suitable for aerospace, die/mold manufacturing, and precision component production.
