An experimental platform produced by Beizhong manufacturer refers to a place where experiments are conducted. It provides a flat surface with certain standard specifications for small-scale experiments, as well as instruments and equipment for large-scale experiments.
Experimental platforms are generally used as reference positioning surfaces in calibration or precision testing. They are suitable for testing the flatness of workpiece surfaces using the coloring method or serving as auxiliary tools for experimental work.
Stiffness Index Requirements for Experimental Platforms
For every 250N (1N=0.102kgf) load applied to the center of the experimental platform's working surface, the deflection of the platform should not exceed 1μm. During testing, the deflection value of platforms at all levels should not exceed half of the flatness tolerance of a Grade 00 platform.
To reduce production costs and make the price of experimental platforms competitive in the market, 99.8% of experimental platform manufacturers adopt manual scraping as part of the production process. Although manual scraping is relatively outdated, for experimental platforms requiring high precision, it is an irreplaceable machining technique that no mechanical processing can substitute. To extend the service life of experimental platforms and ensure their working accuracy, it is recommended to control the scraping depth to above 0.02mm. This ensures a longer service life and calibration cycle for the experimental platform. According to relevant data on scraping depth and measured scraping depth values, this processing requirement is achievable. The appearance of vibration patterns on the experimental platform increases surface roughness, affecting both precision and aesthetics. However, with the scraping process, such issues rarely occur. This process prevents small-scale local distortions on the working surface of the experimental platform, ensuring its usage accuracy. Inspecting the microscopic quality of the experimental platform's working surface, i.e., the flatness of微小峰谷 (micro-peaks and valleys), ensures high surface microscopic quality and wear resistance, thereby guaranteeing the platform's service life.
