The raw material of the caststeel surface table is the high -strength carbon steel and alloy cast steel，whose surface hardness is of HB320-380

.After the two manual handingsuch as 600℃ to 700℃ artificial annealing as well as 2 to 3years of natural aging, the T-slot has plate perfectly resists abrasion and hasstable precision.

The spectification is 200mm×200mm—3000mm×6000mm. For special size, wealso can arrange the production according to the drawing provided by theclient,or after the consultation by both parties.

Precisionaccuracy:T-slot  plates shall beclassified as Grade 0, Grade 1, Grade 2, and Grade 3.

The cast steel plate servesas the measuring basis, which is used for inspecting the machineryparts`geometric tolerance such as flatness ,straightness ,etc. Also, it can beused to the scribbling , abrasive machining equipment installation and more.Cast steel is not only can be used to measuring and inspection workpiece ,butalso service as the plate to grinding, welding, assembly and so on.
