Introduction
The Horizontal Manual Digital Spring Torsion Testing Machine is mainly used to determine the torsional mechanical properties of various springs, raw materials, semi-finished components, and finished components. Test specimens are mounted between adjustable fixtures, allowing the test space to be adjusted according to different specimen sizes. The machine adopts manual loading and digital display, enabling direct measurement and display of torque, torsion angle, and other parameters. It is suitable for torsional performance testing in spring manufacturing, machinery manufacturing, quality inspection, research institutions, and universities.
Application
The Horizontal Manual Digital Torsion Testing Machine is mainly used to test the torsional properties of raw materials, semi-finished components, and finished components. Test specimens are installed between adjustable fixtures, allowing the machine to accommodate specimens of different sizes and perform torsional mechanical performance tests.
