Therefore the use of cast iron plate cast iron materials must be selected, using methods such as aging treatment to eliminate residual stresses of cast iron plate. Base plate is used to check the measurement reference machine parts flatness, straightness tolerance and other forms can also be used for grinding parts marking, installation of equipment and other purposes. Is testing benchmarks mechanical parts flatness, parallelism, straightness tolerance and other forms can also be used for marking, welding and grinding processing and measurement general parts and precision components and so on. The basic platform for sampling physicochemical tests during the manufacturing process, metallurgical analysis, assessment whether the product of the technical indicators. Basic Platform face hardness should HB170-220, crossed flat working surface scraping process should be used. After use wipe the base platform, painted anhydrous acidic anti-rust oil, moisture-proof paper cover, in a clean dry place. Basic platform prior to use non-corrosive gas, anti-rust oil wash the face, and wipe clean with skimmed cotton, can be used. Temperature changes cause measuring errors, should be used within 20 ± 50C range. Basic platform when used carefully to prevent collisions. When you use the basic platform to adjust with a spirit level to level, so that uniform distribution of the pivot fulcrum. The basic platform / base plate size: 200 × 200-2000 × 4000mm (special specifications according to the demand side, drawing production or agreed upon production and processing) the basic platform / base plate Precision: According to the national standard verification procedures, namely 0,1,2 , 3 and fine plane five levels. The basic platform / base plate material: high-strength cast iron HT200-300. Face hardness: HB170-240. This document stems from: http: //rtjxwx.blog.163.com/
