新聞詳情
國外生產的鑄鐵平臺及國內外銷出口的平臺、使用國外設備的汽車鑄鐵平臺等產品常常會接觸到DIN標準，我公司長期為國外汽車試驗設備配套鑄鐵平臺產品， 將DIN標準的具體要求講述： DIN876設計 點在于測量表面的度，底部具備至少三個支撐點。鑄鐵平臺的設計將是例如允許作用在表面上的力朝著所述支撐點，以小化失真被引導的。
FLATNESS測量(liang)在20°C（68°F）標準溫度(du)。測量(liang)表面(mian)的(de)允許變(bian)化到的(de)平面(mian)以微(wei)米（μ）或密耳= 0.001英寸，其(qi)中L是該(gai)板的(de)長邊(bian)的(de)長度(du)。
