This universal testing machine is a new generation of microcomputer controlled electronic universal testing machine specially designed for universities and scientific research institutes. The computer system controls the rotation of the servo motor through the full digital controller, the speed control system controls the rotation of the servo motor, and the deceleration system drives the moving beam up and down through the precision ball screw pair to complete the tensile, compression, bending, shearing and other mechanical properties of the sample. In addition, there are various test accessories, which have a very broad application prospect in the mechanical properties test of metals, non-metals, composite materials and products. This machine is widely used in building materials, aerospace, machinery manufacturing, wire and cable, rubber and plastic, textile, home appliances and other industries of material inspection and analysis, scientific research institutions, colleges and universities, industrial and mining enterprises, technical supervision, commodity inspection and arbitration departments of the ideal testing equipment.
