5-axis machining center STC 1000

horizontalfor aeronauticsfor the aerospace industry

Optimum spindle speed / torque curve characteristic for HPC titanium machining Perfect machine geometry which enables accurate machining A stable, low-vibrations milling process which creates a platform for increased tool service lives and thus greater productivity The STC series has been designed to provide unrivalled economy in the machining of the most demanding structural parts, multi-blades and casings with long cycle times, and provide the customer with a whole host of practical options. These machining centers have excellent static and dynamic properties as well as a tried and tested rotatable head, making them the benchmark for heavy chip removal in titanium and Inconel part for the aerospace and power generation industries. STC 1000 Machine concept Construction Principle Thermo-symmetrical design Elements of closed welded design Extremely stable and low vibration Optimized using the FE method High running and positioning accuracy Short positioning and start-up times thanks to high acceleration Spindles Motor spindles Oil-air lubrication directly through the outer ring (direct lubrication system) Variable hydraulic bearing pretensioning Vector control with constant torque up to the corner speed, thereafter constant power Internal coolant supply as standard Sensors for bearing temperature, thermal spindle growth with compensation and in-process vibration monitoring MT version has hydraulic spindle clamping Gear-driven spindle Drive via two-step gearbox Torque 940 Nm or 1'300 Nm Large dimensioned precision hybrid bearings Oil-air lubrication system Internal coolant supply as standard
