WDW-600 Microcomputer Controlled Electronic Universal Testing Machine

1. Product introduction

WDW-600 microcomputer control electronic universal testing machine is a new generation microcomputer control electronic universal testing machine specially designed for universities and scientific research institutes. The computer system controls the rotation of the servo motor through the all-digital controller, the speed regulating system, and the moving beam is driven up and down by the precision ball screw pair after the deceleration system, to complete the tensile, compression, bending, shearing and other mechanical properties tests of the sample. In addition, a wide variety of test accessories are configured. It has a very broad application prospect in the mechanical properties test of metal, non-metal, 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, is scientific research institutions, colleges and universities, industrial and mining enterprises, technical supervision, commodity inspection arbitration and other departments of the ideal test equipment.
