Multi-Axis Tribometer
The Multi-Axis Tribometer is a versatile tribological testing device for studying friction and wear of materials under low to medium load conditions. It supports multiple contact configurations including pin- or ball-on-rotating-disc and pin- or ball-on-plate reciprocating tests. With a lateral indexing function, the device allows continuous exposure of fresh wear surfaces, making it suitable for fundamental tribology research and various standardized test methods.

Test Procedures
Principle:
The tribometer applies precise normal loads using electric linear actuators. Pins or balls are mounted on gimbal-supported beams and contact rotating discs or reciprocating plates. Friction is independently measured by strain sensors to avoid interference from normal loads. Lateral indexing shifts the contact area during the test, exposing fresh surfaces for multi-track or spiral wear paths, yielding reproducible and stable wear data.
Operation:
(1) Select the module according to the test type and install properly.
(2) Mount samples ensuring proper alignment and fixation.
(3) Set normal load and verify sensor zero.
(4) For elastomer tests, set appropriate dwell time.
(5) Confirm temperature control system stability for high- or low-temperature tests.
(6) Verify lateral travel and speed for indexing tests.
(7) Do not open protective shield during testing.
Experimental Workflow:
ASTM G99 Pin-on-Disc Test
(1) Mount pin/ball and disc samples.
(2) Set track radius and disc speed.
(3) Apply load and configure test duration.
(4) Start the test and record friction data.
(5) Analyze wear after test completion.
ASTM G132 Indexed Wear Test
(1) Set indexing step and feed speed.
(2) Perform multi-track continuous wear loading.
(3) Ensure pins contact fresh surfaces throughout the test.
(4) Record friction coefficient variation across the tracks.
Maintenance Information
(1) Inspect linear actuators and force sensors regularly.
(2) Clean modules and samples to prevent contamination.
(3) Verify temperature control, heating, and cooling modules before high/low temperature tests.
(4) Check indexing mechanism for smooth operation.
(5) Store modular accessories properly to avoid damage.
