Servo-Electric Low Cycle Fatigue (LCF) Central Spindle Testing Machines Series LFMZ

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
