對于磨床來講，對工件的(de)加工精度(du)會造成直接產生影響(xiang)的(de)因素有：磨床的(de)幾何精度(du)、剛(gang)度(du)、熱變形(xing)、運動穩(wen)定性和(he)抗振性等。現代機械設備的(de)發展越來越快，更(geng)多(duo)名詞(ci)也隨之而來，那么(me)你知道(dao)平面磨床的(de)幾何精度(du)是什么(me)嗎?接下(xia)來就讓勤龍(long)磨(mo)床的小編帶你來看(kan)看(kan)吧。

平面磨床的幾何精度指的是不承受負荷的狀態下，各個部件的運動精度和互相位置精度。磨床畢竟是機械制造，不可能絕對精確，總會出現或多或少的誤差。這種誤差一般會在工件加工時的不同程度中反映出來，而影響磨床的工件的加工精度。通常有主軸的徑向跳動和軸向竄動，工作臺等運動部件移動的直線度，工作部件的相互位置誤差和傳動誤差等。
