Testing Principle
The GM-6 operates on a straightforward yet sophisticated principle. A strip-shaped test sample is clamped using a specimen holder, while another sample piece wraps around a slider. The slider is then placed on a sensor hook. Under a defined contact pressure, a motor-driven conveyor belt moves the force sensor, causing the two surfaces to slide against each other.
As the surfaces move, the force sensor captures the friction forces generated. These signals are amplified by an integrator and transmitted to a recorder, which simultaneously calculates and records both the static friction coefficient (the force required to initiate movement) and the dynamic friction coefficient (the force required to maintain movement). This dual measurement capability provides comprehensive insights into material behavior.
