Main Structure, Function and Application Range : This series of machine is a new kind of electronic universal testing machine produced by Jinan Fine Testing Instrument Co., Ltd., which adopts the most advanced and reliable load frame structure of electronic universal testing machine of the world, as well as the AC servo timing system and motor produced by Panasonic Co. Ltd. (Japan). The PC controlling system not only realizes the close-loop control of the parameters such as load, specimen distortion, and crosshead displacement etc., but also realizes the data processing conforming to the requirements of national standard GB228 “Metallic material room temperature tensile test method”. The system realizes the screen display, auto disposing (according to the corresponding test method), and test result disk storage of the test load, test load peak value, crosshead displacement, specimen distortion, as well as the test curve etc. What’s more, we can do the auto measuring and processing of the r & n value of the sheet metal as the first company in China. Especially the application of the control mode, brainpower setting specialist system, and net database make the series machine internationally advanced in technique.
