Universal Testing Machine
Introduction of Universal Testing Machine
Computer-Controlled Electronic Universal Testing Machine features an elegant design, user-friendly operation, and reliable, stable performance. A computer-controlled speed regulation system drives the AC servo motor, which, after deceleration, uses a precision ball screw mechanism to move the crossbeam up and down. This machine performs tensile, compression, bending, and shearing tests on metal and non-metal samples and automatically calculates parameters such as tensile strength, upper and lower yield strength, elongation, non-proportional elongation strength (ReH, ReL, Rp0.2, Fm, Rt0.5, Rm, E), among others. Tests and data are provided according to GB, ISO, DIN, ASTM, JIS, and other international standards. This equipment operates quietly, efficiently, with no pollution, featuring a wide speed adjustment range and extensive crossbeam travel distance. It is ideal for industries like steel, sheet metals, alloys, non-metal materials, quality inspection institutions, and research laboratories.
We can provide 1T, 3T, 5T, 10T, 30T, 60T, 100T Microcomputer-Controlled Electronic Tensile Testing Machine or as your need.

The floor-standing portal structure provides upper space for tensile tests and lower space for compression and bending, with an upper-tensile, lower-compression dual-space design. It features imported backlash-free ball screws and guide rails, offering safety, rigidity, and high coaxiality.
Includes crossbeam displacement limit protection, overload protection, and break-stop protection functions to ensure safe and reliable operation.
Drive System and control system
The AC servo control motor, regulated by a high-precision speed control system, drives the high-precision ball screw mechanism for smooth crossbeam movement, enabling tensile, compression, and bending tests. The arc-toothed synchronous belt system provides high efficiency, long life, low noise, and maintenance-free, backlash-free vertical movement of the crossbeam.
Operates on Windows 7/10 in Chinese, combining a full-digital PC control card with multi-channel I/O and an optical displacement system, utilizing various computer resources for a reliable, advanced system.
Precision Testing System
Equipped with a Lenovo PC for setting up tests, controlling operational states, data collection, processing, display, and printing of test results. The dedicated Windows XP-based intelligent software package allows measurements according to national and international standards, or customer specifications, with test data processing and statistical analysis. Outputs reports and characteristic curves in required formats.
