Assembly plate are usually used to fit and debug theequipment.there are T-slot on the surface plate to fit the workpiece.Additionally, we can machine the round hole U-shaped, slot holes or other yourdesire on the surface plate.

The raw material of the cast iron assembly plate isthe high -strength cast iron HT200-300 ，whose surface hardnessis of HB170-240.After the two manual handing such as 600℃ to 700℃artificial annealing as well as 2 to 3 years of natural aging, the T-slot hasplate perfectly resists abrasion and has stable precision.

Technical requirements of assembly Plate:

1.The working surface, when inspected visually,shall be free from blowholes, sand holes, cracks, slag inclusions scratches,porous patches and other visual flaws.

2.The working surface shall be clean and uniform andthe other sides shall be painted well.

3,The raw material of Cast Iron Surface Plate shallbe the close-grained cast iron whose hardness is of HB 170~220.

4, the surface plate are usually adopted thescraping technology.

5,deviation from flatness of the workingsurface  shall not exceed the permitteddeviations specified in Table2.
