T-slot plate are mainly used as fitting workpieces. Which is the fadation plate of adjustng, assembling and reparing equipments.

The raw material of the cast iron T-slot  is the high -strength cast iron HT200-300 ，whose surface hardness is 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 has plate perfectly resists abrasion and has stable precision.

Precision accuracy:T-slot  plates shall be classified as Grade 0, Grade 1, Grade 2, and Grade 3.

Technical requirements of T-slot 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 and the other sides shall be painted well.

3,the plugging of blowholes or porous patches in the working surface whose accuracy is Grade 0- Grade 3 with material of a similar composition is permitted provided that such a repair does not affect stability or accuracy.

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

5, the surface plate are usually adopted the scraping technology.

6, the surface plate after scraping technology need coloring method for inspection.
