Cast Iron Surface Plate Operating Procedures

For cast iron surface plates, we need some preparation, for example: cleaning the surface of the cast iron plate, can use 120 # solvent gasoline cleaning to wipe. Ready for verification tools. 

Then we carry out the inspection work, appearance and surface quality: according to the requirements of the program, visual observation and test. Cast iron flat face and side surface roughness: comparison of surface roughness comparison sample comparison test. Side angle: with a scale value of 2 'angle gauge for verification. Flatness of cast iron surface: According to the accuracy of the cast iron plate level, the use of verification tools, with diagonal method to test.
