STARRAG STC 1800/170 VERTICAL MACHINING CENTER

Technical Description

The Starrag STC 1800/170 is a high-performance 6-axis vertical machining center engineered for demanding aerospace and defense applications. Featuring expansive work envelope dimensions of 133.85" (3,398.5 mm) X-axis, 74.80" (1,899.9 mm) Y-axis, and 112.20" (2,849.9 mm) Z-axis travel, this machine accommodates large structural components up to 130" × 80" × 80" capacity. The robust 50 hp (37.3 kW) gear-driven spindle delivers 1,300 Nm of torque at 100% duty cycle with an 8,000 RPM maximum speed, enabling material removal rates exceeding 50 cubic inches per minute on titanium. The ISO 50 (HSK-A100) spindle taper ensures precise tool coupling and stability during heavy cutting operations. The sixth axis (A/C head configuration) permits simultaneous 5 and 6-axis machining with full rotary tilt capability, enabling one-hit machining that reduces setup operations and enhances component quality. Advanced thermal management through temperature-controlled coolant and automatic spindle thermal compensation maintains exceptional geometric accuracy. The machine incorporates a 450-position automatic tool changer with RFID verification and laser tool probing for unparalleled process control. Starrag's proprietary thermo-symmetrical design and FE-optimized construction minimize vibration and thermal drift, delivering positioning accuracy to 0.006 mm. Standard features include hydrostatic linear guides, automatic calibration of machine kinematics, and pallet changer functionality for continuous operation. This machining center represents the industry benchmark for aerospace manufacturers requiring robust capability for titanium, stainless steel, and Inconel components in batch production environments.
