How to choose an electronic universal test machine

Electronic universal testing machineIt is divided into single-arm type and door type. The single-arm type is suitable for material tests with a test force below 5KN, and the door structure is suitable for material tests with a test of above 5KN. There are also digital displays and microcomputer controls. Digital displays use high-precision, all-digital system and precision reducer to drive precision lead screw pairs for testing, achieving large-scale adjustment of test speed. Touch key operation mode, LCD display in real time, display interface can display test method selection interface, test parameter selection interface, test operation and result display interface, curve display interface, convenient and fast use.
Microcomputer-controlled electronic universal test machineThe computer system controls the rotation of the servo motor through the speed control system through the controller. After deceleration, the speed reduction system drives the rise and fall of the moving crossbar through the precision lead screw pair, completing various mechanical performance tests such as tensile, compression, bending, and shear of the sample.
There are two types of motors used in electronic universal testing machines: stepper motor and servo motor. The stepper motor runs unstable and may sometimes jump several steps continuously. The control accuracy is low and the price is relatively cheap. The servo motor can feedback information to ensure that each step of the test is smooth, the control accuracy is high, and the price is slightly more expensive.
