對于磨(mo)(mo)床(chuang)來(lai)講，對工(gong)件的(de)加工(gong)精度(du)會造成直接(jie)產生影響的(de)因素(su)有：磨(mo)(mo)床(chuang)的(de)幾(ji)何精度(du)、剛度(du)、熱變形、運動穩定性(xing)和抗振性(xing)等。現代(dai)機械設備的(de)發(fa)展(zhan)越(yue)來(lai)越(yue)快，更多名詞也隨之而(er)來(lai)，那(nei)么(me)你知道平(ping)面磨(mo)(mo)床(chuang)的(de)幾(ji)何精度(du)是什(shen)么(me)嗎?接下(xia)來(lai)(lai)就讓勤龍磨床的小(xiao)編帶你來(lai)(lai)看(kan)(kan)看(kan)(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。
