對(dui)于磨床來(lai)講，對(dui)工(gong)件的(de)加工(gong)精度(du)會(hui)造成直接(jie)產生影(ying)響的(de)因素有：磨床的(de)幾(ji)何精度(du)、剛度(du)、熱(re)變形、運動穩定性(xing)和抗振性(xing)等。現代機械設備的(de)發展越來(lai)越快，更多名詞也隨之而(er)來(lai)，那么(me)(me)你(ni)知道平面磨床的(de)幾(ji)何精度(du)是(shi)什么(me)(me)嗎?接下來就讓(rang)勤龍磨床(chuang)的(de)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。
