Universal Finger Abrasion Tester
The Universal Finger Abrasion Tester simulates the mechanical and chemical interactions between a human finger and a surface. It evaluates the effects of friction, body oils, sweat, and potential chemical reactions on material surfaces over time. The device uses an electronically controlled piston (artificial finger) to replicate realistic wear patterns, providing precise, reproducible results for product durability and surface performance testing.
Application
(1) Friction simulation between fabric and skin
(2) Material wear and dust accumulation simulation
(3) Leather abrasion resistance testing
(4) High-roughness surface mechanical wear evaluation
(5) Chemical effect simulation from hand cream or sunscreen
(6) Artificial sweat chemical interaction testing

Test Procedures
Mount the artificial finger piston onto the test unit.
Fix the material sample securely on the test platform.
Set the desired load, friction diameter, and cycle count.
Initiate the test program; the linear motor applies precise cyclic motion to simulate wear.
Monitor results via the software; after completion, remove the sample for evaluation of wear, abrasion, or chemical effect.
Maintenance Information
(1) Periodically inspect the artificial finger and friction pads for wear.
(2) Clean the sample platform and friction surfaces after each test.
(3) Check electrical connections and linear motor operation regularly.
(4) Calibrate force and cycle counters annually to maintain accuracy.
(5) Lubricate moving components as recommended by the manufacturer.
