Description
1. Product introduction
The product has a novel appearance, and the main body of the frame is composed of a high-rigidity one-time extruded aluminum profile. The unique combination design structure can adjust the test space position according to ergonomics. The high-precision, gap-free precision ball screw improves transmission efficiency and displacement accuracy. The control cabinet with LCD display on the side of the appliance is connected to the right side of the main unit. The F020 controller is applied in the era, and the upper and lower machines can be independently controlled by the switch button on the front panel. Closed-loop control of parameters such as test force, sample deformation and beam displacement can be achieved. The test space is large, and a variety of accessories can be conveniently configured. It is suitable for factories, mines and enterprises, especially institutions of higher learning, scientific research institutions and other departments to conduct mechanical properties such as drawing, pressing and bending of materials.

3. Main features
(1) The main machine is a bracket type single space, the main body of the frame is composed of high-rigidity one-time extruded aluminum profiles, and the unique combined design structure can adjust the test space position according to ergonomics.
(2) The self-developed liquid crystal display control cabinet collector and control unit are hung on the right side of the host, and the upper and lower machines can be independently controlled by switching buttons on the front panel;
(3) The liquid crystal display control cabinet provides a new control method for the electronic universal testing machine, so that the user can conduct general tests without leaving the microcomputer. It has the characteristics of friendly man-machine interface, clear display and convenient operation.
(4) The F020 controller independently developed in the application era can realize closed-loop control of parameters such as test force, sample deformation and beam displacement;
