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, following two manual treatments (manual annealing)600Degree-700Degree and natural aging2-3The product's accuracy remains stable over the year, performing 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 slot platform should be properly sand-cast and smooth, with paint that is firmly adhered.

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 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 processing,3GradeTType groove platform working surface, with a surface roughnessRaThe permissible values are:5um。

⑥The scraping process should be followed by a coloring and fitting inspection. The ratio of contact point areas displayed after fitting is shown in the table.3Regulation: Or as specified25mm×25mmNumber of contact points for square area, see table.3Regulations, and any25mm×25mmContact points should not exceed5Dot.
