Foundation Surface Plate

Applications: The surface use scratching technology and it can be used in any kinds of testing work and can measure parts precisely .At the same time ,it can be used to test and measure benchmark, test parts' size precision and deviation and scribe lines.The feature s of it are high precision and wear-resistant. Surface test: Spread colours on the surface and count spots in 25mm2 ≤25 spots of Gr 0 and Gr 1 Surface Plate ≤20 spots of Gr 2 Surface Plate ≤12 spots of Gr 3 Surface Plate Precision: Generally as per JB/T7974-99.Flatness accuracy as per Gr0 ,Gr1,Gr2,Gr3 and of JB/T7974-99 Material:Made from closed grained cast iron of HT 200-300 . Hardness between 170-240 BHN Spercification: 200mm×200mm-2000mm×4000mm(we can produce and process these products according to the customers’ drawings or requirements) contact person:Sophia Han tel:86-0317-4505966 msn:zhongbozg@msn.com
