50KN Microcomputer-Controlled Wood Universal Testing Machine
**I. Application and Technical Description**
The QX-W700 Microcomputer-Controlled Wood Universal Testing Machine is specifically designed for the evaluation of various physical and chemical properties of wood-based panels and veneered wood panels. It is widely used in testing critical parameters such as surface bonding strength, static bending strength, modulus of elasticity, screw-holding force, and internal bond strength. This machine meets international standards and ensures accurate and reliable results for quality control and research purposes.
**Technical Features**
This advanced testing system utilizes the latest microcomputer control technology. It employs an imported AC digital controller to regulate a servo motor via a synchronous belt, driving a high-precision ball screw mechanism that moves the test bench. The test bench can operate at speeds ranging from 0.001 mm/min to 500 mm/min, offering flexibility for different testing requirements.
The force measurement system uses a high-precision tension and compression sensor imported from the United States, with an accuracy of 0.02%. The entire system achieves a precision level of 0.5%, with an effective force range from 0.2% to 100% of the maximum capacity. The force measurement accuracy is within ±0.5% of the indicated value, while displacement and deformation measurements also maintain similar levels of precision.
