The DWM-3G multifunctional friction tribometer is divided into two types of functions: a high-temperature multifunctional rotating friction module and a low-load reciprocating friction and wear testing module. This machine uniquely integrates these two functions into a single instrument, covering both types of motion modes for friction and wear testing, making it highly powerful. It is an ideal device for testing in universities and research institutes.

The rotary module, which operates through sliding friction, is used to evaluate the performance of engineering plastics, powder metallurgy, and alloy bearings under specified test conditions. It can be tested at temperatures ranging from room temperature to 800℃, under various conditions including oil-free lubrication, oil-lubricated, and changes in load, speed, time, friction pair materials, surface roughness, and hardness. The module can measure material temperature rise and friction coefficient values.

The reciprocating module features a unique lever loading structure, designed for use in reciprocating friction tests. International brands such as FLEX, PCS, and PLINT also employ a similar lever loading method. The working platform is equipped with a servo motor that controls the installation of a worktable on high-precision rails, enabling smooth lateral movement to ensure the linear reciprocating motion of the test sample during the experiment. The maximum reciprocating displacement is 40mm, and the reciprocating speed can be adjusted.

The fixture uses a sample chuck, and the fixture is connected to an S-type friction force sensor. During the test, the measured friction force is collected and displayed in the corresponding column of the computer software

This machine can realize the full digital adjustment of loading force value, linear reciprocating displacement and reciprocating speed to meet the different test needs of customers.

All the motors used in this machine are Panasonic AC servo motors and controllers, featuring a wide speed range, high torque at low speeds, and low noise. The measurement parameters include test force, friction force, test time, and spindle revolutions. When any parameter exceeds the preset value, the corresponding alarm light will illuminate, and the spindle will stop rotating. All test parameters can be displayed on the digital display device and computer screen, recording the temperature-time curve, friction force-friction coefficient-time curve, and test force-time curve.
