Precision rotary friction testing machine

Precision rotary friction testing machineIt is a professional equipment designed for high-precision material friction and wear performance testing, widely used in fields such as aerospace, precision machinery, electronic semiconductors, medical devices, etc. that require strict testing accuracy. Its core function is to simulate rotational friction conditions, accurately measure key parameters such as friction coefficient and wear amount of materials, and provide data support for the research and development, production, and quality verification of high-precision components. It is a core testing tool to ensure product reliability.

From the perspective of device construction, the core consists ofHigh precision rotating unit、Micro load loading system、Precision environmental control moduleandHigh sensitivity data acquisition systemComposition. The high-precision rotating unit adopts air floating spindle or ultra precision ball spindle, with a speed control accuracy of ± 0.1r/min and a rotation coaxiality error of less than 0.001mm, ensuring stable and error free motion of the friction pair; The micro load loading system is driven by piezoelectric ceramics or servo motors, and can apply micro force loads of 0.001-500N with a loading accuracy of ± 0.0001N, meeting the low load friction testing requirements of precision components; The environmental control module can accurately adjust temperature (-40 ℃ -200 ℃, temperature control accuracy ± 0.1 ℃), humidity (20% -80% RH, humidity control accuracy ± 2% RH), and support inert gas protection to avoid environmental factors interfering with detection results; The high-sensitivity data acquisition system is equipped with high-precision sensors, which can capture subtle changes such as friction coefficient (resolution 0.0001) and wear amount (accuracy 0.001mg) in real time. The data sampling frequency is up to 1000Hz, ensuring accurate and reliable detection data.

The core advantages of this device are "ultra-high precision" and "strong stability". Compared to conventional rotary friction testing machines, its accuracy in speed control, load application, data acquisition, and other aspects has been improved by 1-2 orders of magnitude. It can capture wear changes at the micrometer or even nanometer level, meeting the requirements of high-precision material testing; The equipment adopts anti-interference design, and the body shock absorption structure and electromagnetic shielding technology effectively reduce the influence of external vibration and electromagnetic signals on detection. The repeatability error of test data is less than 1%. In addition, the device supports custom testing programs and can preset multiple speed and load change curves to simulate complex rotational friction conditions.
