對(dui)于磨(mo)(mo)床來(lai)講(jiang)，對(dui)工(gong)件的加(jia)工(gong)精(jing)度(du)會(hui)造(zao)成直接產生影(ying)響的因素有：磨(mo)(mo)床的幾(ji)何(he)精(jing)度(du)、剛度(du)、熱變(bian)形(xing)、運動(dong)穩定性(xing)和抗振性(xing)等。現代機械設備的發展越(yue)來(lai)越(yue)快，更(geng)多名詞(ci)也隨之而來(lai)，那么(me)你知道平面磨(mo)(mo)床的幾(ji)何(he)精(jing)度(du)是什么(me)嗎?接(jie)下(xia)來就讓勤龍磨床的小(xiao)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。
