Three-dimensional plate
The raw material ofthree-dimensional plate is the high -strengthHT200-300，whose surface hardness is of HB170-240.
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.
Three-dimensional plateservices as the measuring basis, which is used for insepcting the machineryparts` geometric tolerance, such as flatness,straightness,etc. Also, it can beused to the scribing, abrasive, machineing equipment,installation andmore.there is a coordinate line, which is convenient for CMM.
