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)(zhu)鐵(tie)定(ding)(ding)(ding)盤是立(li)式(shi)車(che)床(chuang)裝(zhuang)夾(jia)工(gong)(gong)(gong)件(jian)(jian)(jian)的(de)(de)(de)新(xin)型隸屬東西。本(ben)來(lai)立(li)式(shi)車(che)床(chuang)只能應(ying)用壓板(ban)螺栓和卡鉗裝(zhuang)夾(jia)工(gong)(gong)(gong)件(jian)(jian)(jian)，車(che)削(xue)(xue)加(jia)(jia)工(gong)(gong)(gong)進(jin)程中反重復(fu)復(fu)地(di)裝(zhuang)拆夾(jia)具(ju)，不(bu)成(cheng)(cheng)能一(yi)次性完成(cheng)(cheng)端面、內(nei)圓(yuan)(yuan)(yuan)、外(wai)圓(yuan)(yuan)(yuan)的(de)(de)(de)車(che)削(xue)(xue)加(jia)(jia)工(gong)(gong)(gong)；還有(you)些(xie)(xie)工(gong)(gong)(gong)件(jian)(jian)(jian)別的(de)(de)(de)加(jia)(jia)焊裝(zhuang)夾(jia)的(de)(de)(de)胎架，鑄(zhu)(zhu)鐵(tie)定(ding)(ding)(ding)盤完成(cheng)(cheng)后再割除胎架，打磨修整，鑄(zhu)(zhu)鐵(tie)定(ding)(ding)(ding)盤尤其(qi)有(you)些(xie)(xie)壁厚不(bu)大的(de)(de)(de)環形工(gong)(gong)(gong)件(jian)(jian)(jian)，假如(ru)(ru)用夾(jia)鉗固定(ding)(ding)(ding) 會變形掉圓(yuan)(yuan)(yuan)，用壓板(ban)螺栓固定(ding)(ding)(ding)，鑄(zhu)(zhu)鐵(tie)定(ding)(ding)(ding)盤工(gong)(gong)(gong)序翻來(lai)覆去很不(bu)便利。既影響加(jia)(jia)工(gong)(gong)(gong)度(du)，鑄(zhu)(zhu)鐵(tie)定(ding)(ding)(ding)盤又操(cao)作復(fu)雜，辛(xin)苦(ku)費時。假如(ru)(ru)采用圓(yuan)(yuan)(yuan)形永磁任務(wu)臺固定(ding)(ding)(ding)工(gong)(gong)(gong)件(jian)(jian)(jian)，鑄(zhu)(zhu)鐵(tie)定(ding)(ding)(ding)盤只須將工(gong)(gong)(gong)件(jian)(jian)(jian)放在圓(yuan)(yuan)(yuan)臺面上(shang)(shang)，再應(ying)用圓(yuan)(yuan)(yuan)臺上(shang)(shang)設置(zhi)的(de)(de)(de)齊心刻(ke)度(du)尺(chi)和齊心滑塊找圓(yuan)(yuan)(yuan)、找正、扭轉磁力(li)開(kai)關，工(gong)(gong)(gong)件(jian)(jian)(jian)即被緊緊吸住。可以一(yi)次性完成(cheng)(cheng)端面、鑄(zhu)(zhu)鐵(tie)定(ding)(ding)(ding)盤內(nei)圓(yuan)(yuan)(yuan)、外(wai)圓(yuan)(yuan)(yuan)的(de)(de)(de)車(che)削(xue)(xue)。此工(gong)(gong)(gong)藝(yi)簡略(lve)、快(kuai)捷(jie)、準確、省力(li)，縮短輔佐任務(wu)工(gong)(gong)(gong)夫(fu)，進(jin)步(bu)任務(wu)效率(lv)。圓(yuan)(yuan)(yuan)形任務(wu)臺上(shang)(shang)還裝(zhuang)備了(le)可以拆開(kai)的(de)(de)(de)導磁條，鑄(zhu)(zhu)鐵(tie)定(ding)(ding)(ding)盤可以在上(shang)(shang)面加(jia)(jia)工(gong)(gong)(gong)成(cheng)(cheng)一(yi)些(xie)(xie)固定(ding)(ding)(ding)工(gong)(gong)(gong)件(jian)(jian)(jian)所需(xu)(xu)的(de)(de)(de)非凡工(gong)(gong)(gong)裝(zhuang)，知足一(yi)些(xie)(xie)非凡車(che)削(xue)(xue)工(gong)(gong)(gong)藝(yi)的(de)(de)(de)需(xu)(xu)求(qiu)。
