Circular plate (circular platform) Caution 
 Circular plate (circular platform) used to conduct the installation. Then, wipe clean the face plate, no problem in identifying the circumstances under which, during use, to avoid the workpiece and the flat face a radical impact, preventing damage to the flat face; the weight of the workpiece can not be more exceed the rated load plate, otherwise it will cause lower quality of work, there may damage the structure of flat, or even result in flat deformation, so that damage can not be used 
 Circular plate (circular platform) is characterized by 
 Circular plate (circular platform) to use worn, you can repair scratch again resume its accuracy. 
 Circular plate (circular platform) can paint parts flatness testing method, with accurate, intuitive and convenient advantages. After scraping the cast iron plate on the table to promote seat, the workpiece is relatively smooth, non-astringent feeling, easy to measure, to ensure the accuracy of measurement. 
 Circular plate (circular platform) quality and quality of heat treatment of cast iron flat performance for greater impact: the larger or residual internal stress due to deformation of the face; or wear and tear because of intolerance can not maintain the precision; or too difficult for shaving less than the value of small roughness. Therefore, using the cast iron plate should be noted that the choice of cast iron, with aging and other methods to eliminate the residual stress in cast iron flat. 

 Riveter platform (riveter flat) with a new structure, new technologies, new technology and quality material casting process. With reasonable design, stable structure, high precision, wear-resistant, long service life. Widely used in machining, tool shop, assembly shop, measuring rooms and precision machining of test and measurement. Selling products, prompt delivery. 
 Riveter platform (riveter flat) Usage: used machinery, engine power test, commissioning, and has good stability and toughness of the plane surface with T-slots, can be used to fixed laboratory equipment. 
 1 height measurement datum: the analytes with the same seat placed on the platform scale, for measuring heights, and finally to its height and then compared with the standard gauge block. 
 (2) crossed the plane: working drawings can be accessed by the size of the dash work. 
 3 parallel to the plane of measurement: Scale fixed seat, then scale the pointer to make contact with the top surface of the analytes, mobile analytes, check the workpiece surface and the flat surface parallel. 
 4 angle measurement datum: the use of riveting work platform for base level, with the angle of the sine bar and regulations, the angle can be measured 
 Riveter platform (riveter flat) Material: high-strength cast iron HT200-300 face hardness of HB170-240, after two manual processing (annealing 600 degrees -700 degrees artificial and natural aging 2-3 years) using the product accuracy stability, good wear resistance. 
 Riveter platform (riveter flat) Accuracy: standard verification procedures according to the national executive, were four grades 0,1,2,3 
 Riveter platform (riveter flat) Specification: (special specifications can be designed and manufactured according to user requirements) 
 ① 100mm × 200mm ------------- 400mm × 400mm (the size suitable for grinding pressure sand flat) precision is 0, 1, 2. 
 ② 400mm × 600mm ------------- 1500mm × 2500mm (This specification applies to manual scraping flat) accuracy of one, two, three. 
 ③ 1500mm × 3000mm ---------- 2000mm × 3000mm (This specification applies to manual scraping flat) accuracy of two, three, fine plane. 
 ④ 2000mm × 4000mm ---------- 3000mm × 10000mm/4000mm × 8000mm accuracy and precision for the three plane.
