Functions and Features

Equipped with a high-precision, fully digital speed control system and precision reduction gearbox, which drives the precision ball screw mechanism to perform testing. The test speed can be adjusted over a wide range, ensuring low noise operation, smooth running, and stable performance during the testing process.

The universal joint adopts a cross-pin structure and is equipped with an angle limitation function. On one hand, it facilitates specimen clamping and ensures testing concentricity; on the other hand, it effectively reduces the influence of irregular specimens on the force sensor.

The machine adopts an easy operation mode with a LCD display for real-time monitoring. The display interface can show the test method selection interface, test parameter setting interface, test operation and result display interface, and curve display interface, providing convenient and efficient operation.

The machine allows fast and slow adjustment of the crosshead movement during specimen clamping and is equipped with overload protection and other safety protection devices.

With an optional computer interface, the machine can be connected to a computer for test process control, data storage, and printing of test results.
