II. Basic Structure
The testing machine boasts a robust construction, comprising a screw-nut drive mechanism, a solid main frame, an intuitive control system, precision sensors, and a sophisticated PC-based force measurement controller.
- Compression section: Features two sturdy vertical columns securely fastened to the base plate, with the lifting screw-nut mechanism positioned beneath the plate for optimal functionality.
- Flexural section: Utilizes a similar dual-column design, anchoring the upper beam to the base plate. The compression load cell resides under the upper beam, with flexural section columns extending downward to integrate seamlessly with the base plate of the compression section.
- Precision is guaranteed by the screw-nut loading mechanism's expertly threaded interlocking system.
- The servo motor is strategically mounted on a base bracket, ensuring smooth, quiet operation.
- A strategically installed PC-based force measurement system is located on the main machine's side for easy access and control.
Say goodbye to cumbersome traditional hydraulic systems, as this machine employs a modern screw-nut drive mechanism powered by a servo motor. Enjoy silent, oil-free operation with a durable, reliable structure. Achieve precise displacement control effortlessly—no need for calibration, just plug in and start your testing journey.
