TT-slot plates are 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 precision of using this product is stable and good annually.

TMolded Channel PlatformFeatures:

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

②TThe surface of the mold platform should be sand-molded and smooth, with paint that is firmly adhered.

③Accuracy Grade:0Grade-3GradeTOn the mold groove platform work surface, diameter less than15mmThe sand holes can be plugged with the same material, with a hardness less than that of the surrounding material. The number of sand holes plugged 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 die and mold platform usually should be processed by scraping. For surfaces processed by scraping techniques,3GradeTMolded groove platform work surface, with a surface roughnessRaThe permissible values are:5um。

⑥Scraping process should undergo color comparison inspection. The ratio of contact point area displayed after the comparison is shown in the table.3Regulations: Or as specified25mm×25mmNumber of contact points for square area is shown in the table.3Regulations, and any25mm×25mmThe number of contact points should not exceed5dot
