Motor testing plate is usedas measuring basis which is applicable to the coloring method test surfaceflatness, or as experimental work aids.

The raw material of theMotortesting plate is the high -strength HB170-350.After the two manual handing suchas 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.
