WDW-300S Microcomputer-Servo-Controlled Electronic Universal Testing Machine (300 kN, High-Capacity Model)

Description

Product Introduction:

The WDW-300S microcomputer‑servo‑controlled electronic universal testing machine (300 kN capacity) is a next‑generation, microcomputer‑controlled device specifically designed for universities and research institutes. The computer system employs a fully digital controller to drive the servo motor via a speed‑regulation unit; after deceleration through a reduction gear set, the motion is transmitted via a precision ball‑screw assembly to raise or lower the crossbeam, enabling tensile, compressive, flexural, shear, and other mechanical property tests. Additionally, it can be equipped with a wide variety of test fixtures, offering broad application potential in the mechanical testing of metals, nonmetals, composite materials, and related products. This machine is widely used for material testing and analysis across industries such as construction materials, aerospace, machinery manufacturing, wire and cable, rubber and plastics, textiles, and home appliances, making it an ideal testing instrument for research institutions, higher education establishments, industrial and mining enterprises, technical supervision agencies, and commodity inspection and arbitration bodies.
