Reference plane inspection and application of cast iron platforms

Workpiece inspection and reference plane of cast iron platform: The accuracy level of cast iron platform is 0, 1, 2, 3, and precision planing. The cast iron platform is made of ribbed plate and box type, and the working surface is rectangular, square or circular. The working surface adopts scraping technology, and the working surface can process V-shaped, T-shaped, U-shaped grooves, circular holes, long holes, etc. The working surface mostly adopts manual scraping technology, and the working surface can process V-shaped, T-shaped, U-shaped grooves, dovetail grooves, circular holes, long holes, etc. The cast iron platform is a flat reference tool used for workpiece inspection or marking. The platform device should be adjusted to the degree and the load should be distributed on each support point, and the environmental temperature should be distributed." During use, vibration should be prevented. Cast iron platforms are flat reference tools used for workpiece inspection or marking. Calibration personnel walk around the platform, and calibration tools are not on the same rigid body as the platform. The instrument support is sturdy and has poor strength.Introduction to Scraping and Fixture Technology for Cast Iron PlatformsThe quality of cast iron and heat treatment on cast iron platforms have a significant impact on the performance of the platform: either the deformation of the working surface due to residual large internal stress, the inability to maintain accuracy due to no damage, or the difficulty of scraping to obtain small roughness values. Therefore, when using cast iron platforms, pay attention to the selection of cast iron materials and use methods such as aging treatment to check the remaining stress on the cast iron platform. Cast iron platforms can be inspected for part flatness using the coloring method, which has the advantages of being intuitive and convenient. The table seat and workpiece are pushed smoothly on the scraped cast iron platform, without any discomfort, making it convenient for measurement. Measure.
