TT-slot plates, also known asTMold and slot workbench, a type of industrial measuring tool, primarily used for securing workpieces. It serves as the fundamental work platform for artisans to adjust, assemble, and repair equipment.

Cast IronHT200-300Work surface hardness is:HB170-240, after two manual treatments (manual annealing)600Degree-700Degree and natural aging2-3The product's accuracy remains stable when used (year).

TMold groove platformFeatures:

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

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

③Precision Grade:0Grade-3GradeTOn the work surface of the die and mold platform, 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 to be plugged on the working surface should not exceed4Pieces, 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 slotting platform typically should be processed by scraping. For those using scraping processing,3GradeTType groove platform working surface, with a surface roughnessRaThe permissible value is5um。

⑥The scraping process should be followed by a color contact inspection. The ratio of the contact point area displayed after the contact inspection is shown in the table.3Regulation: Or by25mm×25mmThe number of contact points for square area is shown in the table.3Regulations, and any25mm×25mmContact points should not exceed5dot
