The raw material of the cast steel surface table is the high -strength carbon steel and alloy cast steel，whose surface hardness is of HB320-380
.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.
The spectification is 200mm×200mm—3000mm×6000mm. For special size, we also can arrange the production according to the drawing provided by the client,or after the consultation by both parties.
Precision accuracy:T-slot plates shall be classified as Grade 0, Grade 1, Grade 2, and Grade 3.
The cast steel plate serves as the measuring basis, which is used for inspecting the machinery parts`geometric tolerance such as flatness ,straightness ,etc. Also, it can be used to the scribbling , abrasive machining e installation and more. Cast steel is not only can be used to measuring and inspection workpiece ,but also service as the plate to grinding, welding, assembly and so on.
