Starrag USA Inc. STC 800 MT VERTICAL MACHINING CENTER

Technical Description

The Starrag USA Inc. STC 800 MT Vertical Machining Center is a high-performance 5-axis machining solution designed for heavy-duty and precise machining tasks, especially suited for aerospace and energy industries. It features a robust vertical spindle with an HSK-A100 taper, capable of speeds up to 15,000 RPM (standard) with an option for 8,000 RPM, powered by a 49.6 HP motor rated for 30 minutes. The machine supports large workpieces weighing up to 4,410 lbs on a standard 31.5" x 31.5" table, with an optional extended table size of 39.4" x 31.5" for increased versatility. Its chain-type automatic tool changer accommodates 60 tools, expandable to 240, supporting high-mix production demands. The STC 800 MT offers extensive travels with 57.1" in X, 47.2" in Y, and 51.1" in Z axes, and full 5-axis control including rotary axes A (160°) and B (360°). Rapid traverse rates reach up to 2,362 inches per minute on linear axes, maximizing throughput. The machine combines heavy metal cutting capabilities with thermal stability and precision, enabled by its rigid build, advanced spindle design, and Siemens CNC control, ensuring contour fidelity and high surface finish quality during simultaneous 5-axis machining. It also integrates a standard pallet changer with two pallets for efficient workpiece handling. This machining center excels in processing complex structural parts with long cycle times, such as titanium and Inconel components, by providing a thermosymmetrical, vibration-damped structure and advanced axis measurement systems.
