The computer system uses a full digital controller to control the rotation of the servo motor through the speed control system. After deceleration through the deceleration system, the moving beam is driven up and down by the precision ball screw pair to complete the stretching, compression, bending, shearing and more A variety of mechanical performance tests, in addition to a wide variety of test attachments, have a very broad application prospect in the mechanical performance tests of metals, non-metals, composite materials and products. The machine is widely used in the inspection and analysis of materials in construction and building materials, aerospace, machinery manufacturing, wire and cable, rubber and plastics, textiles, home appliances and other industries. It is an ideal test equipment for scientific research institutions, colleges, industrial and mining enterprises, technical supervision, commodity inspection and arbitration and other departments.
