Cast Iron Square Tube instrument with Competitive

Cast Iron Square Tube & Competitive Price Usage: It is applicable to various inspections and benchmark planes for accuracy measurement. It can be used as the measurement benchmark for machine tool inspection and to inspect the dimension accuracy or running difference with the function of performing precise lineation. It is an inevitable tool during machine manufacturing. Materials and Processing: The material of our surface plate is high strength cast iron HT200-300,working surface degree of hardness is HB170-240, undergoes two manual handlings(artificial annealing 600 degrees-700 degrees with natural aging 2-3years) to make the product stable in accuracy and good in grinding resistance. Gray cast iron material. Working surface finished by hand scraping, it is widly used to test the straightness and flatness of workpiece and equipment installing. Best working temperature 20±5°C.Specification (mm)Parallelism of Working SurfaceFlatness of Working SurfacePerpendicularity of Working SurfaceAccuracy Grade (μm)121212100×100×100242424150×150×150363636200×200×200482.5448300×300×3006122.54612400×400×40081648816500×500×50020405122040 Also,wecould according to the customer`s requirments and drawings to produce.
