data-filtered="filtered"/><span style="color: rgb(50, 50, 50); font-family: Verdana, Arial, Helvetica, sans-serif;">圓形平板（圓形平臺）用途：適用于各種檢驗工作，精密測量用的基準平面；用于機床機械檢驗測量基準；檢查零件的尺寸精度或形為偏差，并作緊密劃線(xiàn)，在機械制造中也是不呆缺少的基本工具。 </span><br style="color: rgb(50, 50, 50); font-family: Verdana, Arial, Helvetica, sans-serif;" data-filtered="filtered"/><span style="color: rgb(50, 50, 50); font-family: Verdana, Arial, Helvetica,

rgb(50, 50, 50); font-family: Verdana, Arial, Helvetica, sans-serif;">圓形平臺的毛坯檢驗主要是檢驗外觀(guān)規格是否可以達到技術(shù)要求，和毛坯有沒(méi)有內部缺陷；圓形平臺的機械加工檢驗主要是檢驗圓形平板有沒(méi)有沙孔、氣孔、裂紋、夾沙、縮松和加工誤差等；圓形平臺的成品檢驗主要是檢驗圓形平板的平面度和外觀(guān)及其規格是否可以達到使用要求。</span><br style="color: rgb(50, 50,
