LFMZ Electromechanical High-Precision Central Spindle Machines The LFMZ testing systems are central spindle electromechanical fatigue reverse Testing Machines specially designed for slow speed and slow strain rate applications including Creep & Relaxation, LCF (Low-Cycle Fatigue), TMF (Thermo-Mechanical Fatigue) and general slow speed static and quasi-dynamic cyclic testing. To assure highest control accuracy even at lowest strain rates and long-term trouble-free operation in static and cyclic fatigue reverse modes the spindle system of the LFMZ Series is fully bedded in oil os as reduce friction in the spindle to a minimum. Key Features • - Ultra-high mechanical resolution for most accurate control • - System with high-resolution ball screw driven actuator with pre-stressed ball nut and backlash. Free torsion security device controlled by a high responsive servomotor completely bedded • - Spindle system complete beded in oil to reduce friction (for best control accuracy also at slowest speeds) and extend lifetime of the spindle • - Machine frame in rigid two hard-chromium-plated column construction, precisely aligned with movable upper crosshead, mounted on the welded machine’s base frame • - Crosshead lifts available from manual adjustment to automatic lifts • - Dust protection over the full stroke • - Adjustable maximum and minimum switches • - With precision flat load cell for accurate force measurement and control • - Incremental (digital) spindle stroke transducer for accurate displacement measurement and control • - Compact and space saving design
