電機試驗平臺材質：工作面硬度為HB170-350，經過兩次人工處理（人工退火600度-700度和自然時效2-3年）對實驗平臺，鑄鐵平板進行熱處理的目的是減少逐漸中的應力，消除鑄鐵平板的部分白口組織，提高鑄鐵工作臺工作表面的硬度和耐磨性，使該鑄鐵平臺，鑄鐵平板的精度穩(wěn)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 as600℃to700℃artificial annealing as well as 2 to 3 years of natural aging, the T-slot has plate perfectly resists abrasion and has stable precision.
