對(dui)于磨(mo)床來(lai)講，對(dui)工件的加工精度(du)(du)會造成直接產生(sheng)影響的因素有：磨(mo)床的幾(ji)(ji)何精度(du)(du)、剛度(du)(du)、熱變形、運動穩定性和抗振性等。現代機(ji)械(xie)設備的發展越來(lai)越快，更多名詞也(ye)隨之(zhi)而來(lai)，那(nei)么你知道平(ping)面磨(mo)床的幾(ji)(ji)何精度(du)(du)是什么嗎?接(jie)下(xia)來(lai)就讓勤(qin)龍(long)磨(mo)床(chuang)的小編(bian)帶(dai)你(ni)來(lai)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。
