- Inspection surface plate is used as the datum for measurement of the machinery parts’ geometric tolerance,such as flatness, parallelism, straightness and more. It is also can be used for precision inspection, marking out (layout), and tooling setup.
铸铁平台材质: 材料为高强度铸铁HT200-250工作面硬度为HB160—210。经过两次处理(人工退火600度----700度或自然时效2---3 年)，使该产品的精度稳定，耐磨性能好。
The material of Cast Iron Inspection Plate is high-strength cast iron Ht200-250 and the hardness of the working surface is HB 160-210. After artificial heat aging treatment( Artificial annealing temperature 600℃ to 700℃or 2-3 years natural aging) the internal stress was totally eliminated, so the surface plate have stable accuracy and good wear-resisting performance.
铸铁平台精度：按国家标准计量检定规程执行，分别为0，1，2，3级四个级别
The Cast Iron Surface Plate can be classified as Grade 0,1,2,3,4 according to the national standard metrological verification procedures
