Medium-sized test platform

During the production process of medium-sized test platforms (medium-sized test plates), there may be weight deviations. The design of cast iron medium-sized test platforms often takes into account casting errors and machining errors. The weight error of cast iron platforms should generally not exceed 10%. When it exceeds 10%, further quality evaluation of the cast iron medium-sized test platform is necessary to determine whether the cast iron platform can be put into use.

The medium-sized testing platform adopts a manual scraping and grinding process. Although manual scraping is relatively backward, for experimental platforms, it is a machining process that cannot be replaced by any mechanical processing under high precision requirements. In order to improve the service life and working accuracy of the medium-sized testing platform, it is recommended to control the scraping and grinding to be above 0.02mm, which can have a longer service life and calibration cycle. According to relevant information on scraping and grinding, as well as the data obtained from scraping and grinding, this process processing requirement can be achieved. Vibration lines appear on the appearance, increasing the roughness of the product surface, affecting accuracy and aesthetics. After the scraping and grinding process, the above problems rarely occur. To prevent small-scale local distortion on the working surface and improve the accuracy of the use of medium-sized testing platforms. Check the micro quality of the surface, that is, the flatness of small peaks and valleys. Only when the surface is micro and good, can the service life of the testing platform be tested.
