QX-862DF Headset Earphone Torsion Testing Machine 
I. Overview of this machine:
This testing machine is specifically designed for conducting fatigue life tests on head-mounted headphones and earphones, as well as for measuring torque values. It can determine whether the device still maintains its force or the resistance at the shaft increases and causes damage to the plastic body after multiple rotations. It features adjustable angles, customizable number of rotations, display of torque values, and automatic shutdown when the set number of rotations is reached. 
This machine is equipped with an intelligent 7-inch touch screen + PLC + servo motor control. The angle setting is angle-based without the need for mechanical adjustment. You can directly input the angle, number of times, and speed on the touch screen, and the machine will automatically reset and complete the test. It is suitable for use in headphone factories and research institutions for development and evaluation purposes.
