TT-slot plates, also known asTType groove 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 hardnessHB170-240, following two manual processes (manual annealing)600Degree-700Degree and natural aging2-3Year) The product's accuracy is stable and good.

TMold Groove PlatformFeatures:

①TThe work surface of the mold channel 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 properly sand-molded and smooth, with paint that is firmly adhered.

③Precision Grade:0Grade-3GradeTOn the work surface of the mold slot platform, diameter less than15mmThe sand holes can be plugged with the same material, but their hardness should be less than that of the surrounding material. The number of sand holes to be plugged on the working surface should not exceed4Individual units, with the spacing between sand holes not to 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 work surface of a slotting platform typically should be processed by scraping. For those utilizing scraping processing,3GradeTWork surface of the slotting platform, with a roughnessRaThe permissible value is5um。

⑥The scraping process should undergo a coloring and mating inspection. The ratio of contact point areas displayed after mating is shown in the table.3Regulation: Or as specified25mm×25mmNumber of contact points for square area, see table3Regulations, and any25mm×25mmThe number of contact points should not exceed5Dot.
