电机试验平台材质：工作面硬度为HB170-350，经过两次人工处理（人工退火600度-700度和自然时效2-3年）对实验平台，铸铁平板进行热处理的目的是减少逐渐中的应力，消除铸铁平板的部分白口组织，提高铸铁工作台工作表面的硬度和耐磨性，使该铸铁平台，铸铁平板的精度稳定，耐磨性能好。
Motor testing plate is used as measuring basis which is applicable to the coloring method test surface flatness, or as experimental work aids.
The raw material of theMotor testing plate is the high -strength HB170-350.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.
