TT-slot plates, also known asTType-slot workbench, a type of industrial measuring tool, primarily used for fixing workpieces, serving as the fundamental work platform for fitters to adjust, assemble, and repair equipment.
Cast IronHT200-300Working surface hardness:HB170-240, after two manual treatments (manual annealing)600Degree-700Degree and natural aging2-3The product's accuracy remains stable when used annually, performs well.
TMold Groove PlatformFeatures:
①TThe work surface of the mold platform must not have defects such as sand holes, gas holes, cracks, shrinkage porosity, scratches, dents, and rust spots that significantly affect appearance and usability.
②TThe surface of the mold platform should be sand-molded and smooth, with paint that is firmly applied.
③Precision Grade:0Grade-3GradeTOn the work surface of the mold groove platform, diameter less than15mmThe sand holes allow for blocking with the same material, with a hardness less than that of the surrounding material. The number of sand holes that need to be blocked on the working surface should not exceed4Pieces, and the spacing between sand holes should not be less than80mm。
④TThe mold slot platform should be adopted Manufactured from fine gray cast iron or alloys, the working surface hardness should reach170-220HB。
⑤TThe working surface of the profiled platform usually should be processed by scraping. For scraping operations,3GradeTT-slot platform work surface, with a roughness textureRaThe permissible value is5um。
⑥The coloring and mating inspection should be conducted after the scraping process. The ratio of the contact point area displayed after mating is shown in the table.3Regulation: Or as specified25mm×25mmThe number of contact points for square area is listed in the table.3Regulations, and any25mm×25mmThe contact points should not exceed each other.5Dot.
