Grooved plate material: high-strength cast iron. The H working surface hardness is HB. The grooved plate has been processed twice (annealing degree and natural aging). The accuracy of using this product is stable and the wear resistance is good.
< , , Specifications of grooved plate** (can also be made into other specifications according to actual requirements)
< , , The precision of grooved plate is carried out in accordance with the standard metrology and verification procedures, respectively, , , , and fine planing Five levels (the smaller the value, the higher the accuracy)
< , , Grooved plate identification
< , , There should be no rust, scratches, bruises and other effects on the working surface of the grooved plate Cosmetic defects of use.
< , , There should be no casting defects such as sand holes, pores, cracks, slag inclusions and shrinkage porosity on the grooved flat working surface. Each casting surface should be completely clean of molding sand, smooth and firmly painted, and all edges should be blunted.
< , , The grooves on the opposite sides of the plate should have settings for mounting handles or lifting positions, threaded holes or cylindrical holes. When setting up the lifting position, consideration should be given to minimizing deformation caused by lifting.
< , , Grooved plates should be stabilized and demagnetized.
< , , , The vertical tolerance of the grooved flat working surface and the side and the adjacent two sides is grade (according to the provisions of B "Shape and Position Tolerance")
< , , , The hardness of the grooved flat working surface Should be HB or between.
