Three-dimensional plate
The raw material of three-dimensional plate is the high -strengthHT200-300，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.
Three-dimensional plate services as the measuring basis, which is used for insepcting the machinery parts` geometric tolerance, such as flatness,straightness,etc. Also, it can be used to the scribing, abrasive, machineing e,installation and more.there is a coordinate line, which is convenient for CMM.
