Manufacture of cast iron platform is based on the standard JB / T7974-1999 manufacture. Iron platform Application: Suitable for a variety of inspection, precision measurement of the reference plane, the dimensional accuracy of machine tools for measuring reference check form part of or deviation, and for precision marking. In machinery manufacturing is not a lack of basic tools. Iron platform is structured into plate and box-style ribs; use is divided into inspection plate, crossed plate and pressure sand flat; 00,0,1,2,3 divided by grade level accuracy flat, where two or more for inspection plate, three of crossed plate. Cast iron platform Material: The material is high-strength cast iron HT200-250 face hardness HB160-210. After two treatment (artificial annealing 700 degrees or 600 degrees ---- 2 --- 3 years of natural aging), so that the accuracy of the product stability, good wear resistance. Cast iron platform Precision: According to the national standard verification procedures, namely 0,1,2,3 grade four level. Cast iron platform specifications :( special specifications can be designed and manufactured according to user requirements) ①100mm × 200mm ------------- 400mm × 400mm (This specification applies to the grinding pressure sand cast iron platform) accuracy of 0, 1 level 2. ②400mm × 600mm ------------- 1500mm × 2500mm (This specification applies to manual scraping iron platform) accuracy of one, two, three. ③1500mm × 3000mm ---------- 2000mm × 3000mm (This specification applies to manual scraping iron platform) accuracy of two, three, fine plane. ④2000mm × 4000mm ---------- 3000mm × 10000mm / 4000mm × 8000mm accuracy of 3 and fine plane.
