TT-slot plates are also known asTMolded槽 workbench, a type of industrial measuring instrument, primarily used to secure workpieces, serving as the foundational work platform for mechanics to adjust, assemble, and repair equipment.

Cast IronHT200-300Working surface hardness:HB170-240, following two manual processes (manual annealing)600Degree-700Degree and natural aging2-3The precision of using this product is stable and good.

TType Slot PlatformFeatures:

①TThe work surface of the mold platform must not have defects such as sand holes, gas holes, cracks, shrinkage, scratches, dents, rust spots, etc., which significantly affect appearance and usage.

②TThe surface of the mold platform should be properly molded with molding sand and be smooth, with a durable paint finish.

③Precision Grade:0Grade-3GradeTOn the mold groove platform work surface, diameter less than15mmThe sand holes allow for blocking with the same material, with the hardness being less than that of the surrounding material. The number of sand holes that need to be blocked on the working surface should not exceed4Individuals, and the spacing between sand holes should not be less than80mm。

④TT-slot platforms should be used   Manufactured from fine gray cast iron or alloys, the working surface hardness should reach170-220HB。

⑤TThe work surface of the profiled platform typically should be processed by scraping. For scraping operations,3GradeTTrough platform work surface, with a roughness textureRaThe permissible value is5um。

⑥The scraping process should be followed by a color matching inspection. The ratio of contact point areas displayed after matching is shown in the table.3Regulation: Or as specified25mm×25mmThe number of contact points for square area is shown in the table.3Regulations, and any25mm×25mmThe contact points should not exceed each other.5dot
