Rigid 6-column machine frame with high stiffness providing superior axial and lateral stiffness and guarantees robust, durable and long-term operation
High machine stiffness and appropriate machine mass reduces shock at sample failure and provides smooth breaking
Two high resolution ball screws driven with pre-stressed ball nuts and low backlash reducing gear system provides high load capacity and high mechanical resolution
Spindle with flange double-nut, sealed and greased for long maintenance intervals
Spindle, flange double-nut and ball-screw shaft grinded pairwise for reduced pitch error
Controlled by a brush-less high responsive, maintenance-free and low noise AC servomotor to drive the mobile traverse guarantees positioning accuracy and repeatability
AC servomotor provides continuous high test speed up to nominal force for continuous operation
Ball Screws (spindles) protection over full travel through oil- and moisture-resistant, sealed bellows made from polyester fabric, coated with polyurethane inside and out side
Additional four (4) hardened and chromium plated guiding columns for increased lateral stiffness
Adjustable end-stops in both (UP/DOWN) directions for the best protection of operator, test sample and machine
End stops for maximum travel protection
One-point spindle lubrication
Precision strain gauge load cell mounted on (movable) crosshead
Alignment fixtures mounted between crosshead and load cell with related alignment verification equipment optionally available
Electrical cabinet with air-fan, complete power supply and control module, relays etc. mounted on rear side of machine’s base
Emergency stop direct at the machine
Durable structured coating (paint)
Use of high quality components and assemblies of reputable companies
Bolts for machine lifting
Adjustable feet for leveling the testing machine
The machine is free-standing on shock absorbers, requiring no special foundations
Ergonomic working height
