WDW Series Electronic Universal Testing Machine


Performance characteristics:
1. High-precision, low resistance, to reverse zero clearance and linear low driving force to ensure extended service life;
2. High-precision control and repeatable measurement results ensure a more realistic reflection of the specimen characteristics;
3. Four-column double-screw double space rigid frame structure, linear travel to ensure the crosshead neutral, thereby reducing test data error, raise experimental accuracy;
4. The digital closed-loop position control servo motor and gear reducer drive mechanism, the servo motor having a large torque output can be realized in a wider load range of high-precision speed control, quick response and full performance;
5. The high degree of intelligence system has a self-diagnostic function. It can automatically detects over-voltage, over-current, over-temperature;
6. Automatic hydraulic grip prevents sample slippage. The adjustable gripping pressure prevents damage to the soft material specimen to improve the accuracy of test results;
7. Optional double cylinder synchronous hydraulic grip, huge clamping force, specimen doesn’t slip. The adjustable pressure to prevent damage to the soft material sample, improving the accuracy of the test results;
8. High-precision tension and compression bi-directional load cell, strong resistance to lateral and impact;
9. There are dozens of different types of fixtures, to meet the different requirements of various industries material testing;
10. Aluminum cover for easy cleaning and a long-lasting-life;
Applications:
 Metal wire, strip, bar, tube,l sheet;
 Rebar, strand;l
