1Overview of testing machine

WDW-2020The series of microcomputer controlled electronic testing machines are mainly used for tensile, compressive, bending and other performance tests of non-metallic and metallic materials. The host is a portal strength frame. The mechanical transmission adopts circular arc synchronous toothed belt and ball screw transmission. Since there is no need for a reducer, the main power of the machine is small, and there is no gap transmission. It has the characteristics of long service life, low noise, and no maintenance, and can be tested for low cycle fatigue. The testing machine consists of a main unitPCComposed of machine control system, user software package, functional accessories, and other components.

IIThe testing machine has the following characteristics：

1. Computer controlled screen displays experimental curve,It can automatically calculate data such as tensile strength, bending strength, and bending modulus. With an open data structure, users can customize formulas to calculate according to their own needs.

2. High measurement force resolution, no change in full range, no grading；

3. It has automatic calibration, automatic zeroing, and automatic storage functions.

4. Adopting a digital speed regulation system, the speed regulation range is wide, the stability is good, the transmission is smooth, and the noise is low;

5. Equipped with a large deformation extensometer

6. Other fixtures can be selected according to user needs.
