圓形任務臺又名圓形鑄鐵定盤，圓形機床定盤，裝備了可以拆開的導磁條，鑄鐵定盤可以在上面加工成一些固定工件所需的非凡工裝，知足一些非凡車削工藝的需求。
鑄(zhu)鐵(tie)定(ding)(ding)(ding)盤(pan)(pan)是立式車(che)床(chuang)裝夾(jia)工(gong)(gong)件(jian)的(de)(de)(de)新型隸(li)屬東西(xi)。本來立式車(che)床(chuang)只(zhi)能應(ying)用(yong)(yong)壓板螺(luo)栓和(he)卡鉗(qian)裝夾(jia)工(gong)(gong)件(jian)，車(che)削加工(gong)(gong)進程中反重復(fu)復(fu)地裝拆(chai)(chai)夾(jia)具，不(bu)成能一(yi)次(ci)性完(wan)成端(duan)(duan)面(mian)、內圓(yuan)(yuan)、外圓(yuan)(yuan)的(de)(de)(de)車(che)削加工(gong)(gong)；還(huan)有(you)些(xie)(xie)(xie)工(gong)(gong)件(jian)別的(de)(de)(de)加焊裝夾(jia)的(de)(de)(de)胎架，鑄(zhu)鐵(tie)定(ding)(ding)(ding)盤(pan)(pan)完(wan)成后再割除胎架，打(da)磨修整，鑄(zhu)鐵(tie)定(ding)(ding)(ding)盤(pan)(pan)尤其有(you)些(xie)(xie)(xie)壁厚不(bu)大的(de)(de)(de)環(huan)形(xing)(xing)工(gong)(gong)件(jian)，假(jia)如用(yong)(yong)夾(jia)鉗(qian)固定(ding)(ding)(ding) 會(hui)變形(xing)(xing)掉圓(yuan)(yuan)，用(yong)(yong)壓板螺(luo)栓固定(ding)(ding)(ding)，鑄(zhu)鐵(tie)定(ding)(ding)(ding)盤(pan)(pan)工(gong)(gong)序翻來覆去(qu)很不(bu)便利。既影(ying)響加工(gong)(gong)度(du)，鑄(zhu)鐵(tie)定(ding)(ding)(ding)盤(pan)(pan)又操作(zuo)復(fu)雜，辛(xin)苦費時。假(jia)如采用(yong)(yong)圓(yuan)(yuan)形(xing)(xing)永磁(ci)任(ren)務(wu)臺固定(ding)(ding)(ding)工(gong)(gong)件(jian)，鑄(zhu)鐵(tie)定(ding)(ding)(ding)盤(pan)(pan)只(zhi)須(xu)將(jiang)工(gong)(gong)件(jian)放在圓(yuan)(yuan)臺面(mian)上，再應(ying)用(yong)(yong)圓(yuan)(yuan)臺上設置的(de)(de)(de)齊心刻度(du)尺和(he)齊心滑塊找圓(yuan)(yuan)、找正(zheng)、扭轉磁(ci)力(li)開關，工(gong)(gong)件(jian)即被緊(jin)緊(jin)吸住。可以一(yi)次(ci)性完(wan)成端(duan)(duan)面(mian)、鑄(zhu)鐵(tie)定(ding)(ding)(ding)盤(pan)(pan)內圓(yuan)(yuan)、外圓(yuan)(yuan)的(de)(de)(de)車(che)削。此工(gong)(gong)藝簡略、快捷(jie)、準確、省力(li)，縮短輔佐任(ren)務(wu)工(gong)(gong)夫，進步任(ren)務(wu)效率。圓(yuan)(yuan)形(xing)(xing)任(ren)務(wu)臺上還(huan)裝備了可以拆(chai)(chai)開的(de)(de)(de)導磁(ci)條，鑄(zhu)鐵(tie)定(ding)(ding)(ding)盤(pan)(pan)可以在上面(mian)加工(gong)(gong)成一(yi)些(xie)(xie)(xie)固定(ding)(ding)(ding)工(gong)(gong)件(jian)所需的(de)(de)(de)非(fei)凡工(gong)(gong)裝，知足一(yi)些(xie)(xie)(xie)非(fei)凡車(che)削工(gong)(gong)藝的(de)(de)(de)需求。
