Technical Description
The 2017 Grob G550 Horizontal Machining Center is a high-performance 5-axis CNC machining platform engineered for precision, flexibility, and reliability in demanding manufacturing environments such as aerospace, automotive, and energy sectors. It features a Siemens 840D CNC control system, providing advanced programming, diagnostics, and multitasking capabilities. The machine utilizes an A/B axis tilting rotary table with a swivel range of -185° to +45° on the A-axis and 360° indexing on the B-axis, enabling full 5-axis simultaneous interpolation for complex geometries. The G550 is equipped with a robust 43 hp spindle motor capable of reaching speeds up to 16,000 RPM, utilizing an HSK-A63 spindle taper to ensure precision tool holding and quick tool changes. Its tool magazine accommodates up to 50 tools, supporting efficient multi-tool operations and minimal chip-to-chip time.
The machine's travels include an X-axis of 31.5 inches, a Y-axis of 40.2 inches, and a Z-axis of 38.2 inches, paired with a 30.31-inch diameter rotary table with a pallet load capacity of approximately 1,653 pounds. Its horizontal spindle orientation with tunnel design optimizes chip evacuation and allows machining of large parts with extended tool lengths without collision. Additional features include high-pressure through-spindle coolant, advanced Grob diagnostics, Renishaw probing technology for in-process measurement, chip conveyors, mist collectors, and oil skimmers, making it suited to handle materials like aluminum, steel, and titanium with exceptional accuracy and surface finish. The machine’s rigid construction and sophisticated thermal compensation assure consistent precision, stability, and productivity in complex multi-axis milling operations.
