    • 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. 鑄鐵平臺材質: 材料為高強度鑄鐵HT200-250工作面硬度為HB160—210。經過兩次處理(人工退火600度----700度或自然時效2---3 年),使該產品的精度穩定,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. 鑄鐵平臺精度:按國家標準計量檢定規程執行,分別為0,1,2,3級四個級別 The Cast Iron Surface Plate can be classified as Grade 0,1,2,3,4 according to the national standard metrological verification procedures
