Introduction
SDS Automatic Spring Testing Machine is a new type of spring testing machine combining professional electronic technology and mechanical transmission, with accurate loading speed and force measurement range, and high precision and sensitivity for the measurement and control of load, deformation and displacement. It is mainly suitable for the load test of tensile and compressive force of elastic devices such as springs, rubbers, and reeds under a certain working length.
Features
● High-precision sensor to ensure test accuracy.
● Imported digital AC servo system, high transmission efficiency, low noise and good stability.
● High-precision ball screw to improve transmission efficiency and displacement accuracy.
● Two-speed preset to achieve high-speed approximation and low-speed acquisition.
● After the test is completed, it can automatically return to the starting point.
● Power-saving design of automatic shutdown without operation, and the shutdown time can be set freely.
● Four units of N, kgf, lbf, and ozf are automatically interchanged.
● 10 sets of test data can be stored.
● It can store 3 sets of curve data, and can view the data of each point, and the test report can be printed by the built-in micro printer.
● With multi-point test, the printing stiffness can be tested.
● It has seven test modes: manual, fixed force, positioning shift, fixed force cycle, positioning shift cycle, fixed force multi-point test, and positioning shift multi-point test to achieve various test requirements of the spring.
● The deviation value of the upper and lower limits can be set freely.
● 800 x 480 pixel TFT true color screen, peak, real-time value and test process curve are displayed on the same screen, which can monitor and track the whole process of testing
