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)盤是立式(shi)車(che)床(chuang)裝夾(jia)工(gong)(gong)(gong)(gong)(gong)件(jian)的(de)(de)新型隸屬東西(xi)。本來立式(shi)車(che)床(chuang)只能(neng)應(ying)用(yong)壓板螺(luo)栓和卡鉗裝夾(jia)工(gong)(gong)(gong)(gong)(gong)件(jian)，車(che)削(xue)加(jia)工(gong)(gong)(gong)(gong)(gong)進(jin)程中反重(zhong)復(fu)復(fu)地裝拆(chai)夾(jia)具(ju)，不(bu)成能(neng)一次(ci)性完成端面、內(nei)圓(yuan)、外(wai)圓(yuan)的(de)(de)車(che)削(xue)加(jia)工(gong)(gong)(gong)(gong)(gong)；還有些(xie)工(gong)(gong)(gong)(gong)(gong)件(jian)別的(de)(de)加(jia)焊裝夾(jia)的(de)(de)胎架(jia)，鑄(zhu)(zhu)鐵(tie)定(ding)(ding)盤完成后再割除胎架(jia)，打磨修整，鑄(zhu)(zhu)鐵(tie)定(ding)(ding)盤尤其有些(xie)壁厚不(bu)大的(de)(de)環形(xing)工(gong)(gong)(gong)(gong)(gong)件(jian)，假(jia)如(ru)用(yong)夾(jia)鉗固(gu)定(ding)(ding) 會變形(xing)掉圓(yuan)，用(yong)壓板螺(luo)栓固(gu)定(ding)(ding)，鑄(zhu)(zhu)鐵(tie)定(ding)(ding)盤工(gong)(gong)(gong)(gong)(gong)序(xu)翻來覆(fu)去很不(bu)便利(li)。既(ji)影響加(jia)工(gong)(gong)(gong)(gong)(gong)度(du)，鑄(zhu)(zhu)鐵(tie)定(ding)(ding)盤又操作復(fu)雜，辛苦費時。假(jia)如(ru)采用(yong)圓(yuan)形(xing)永磁(ci)任務(wu)臺固(gu)定(ding)(ding)工(gong)(gong)(gong)(gong)(gong)件(jian)，鑄(zhu)(zhu)鐵(tie)定(ding)(ding)盤只須將工(gong)(gong)(gong)(gong)(gong)件(jian)放在(zai)圓(yuan)臺面上(shang)(shang)，再應(ying)用(yong)圓(yuan)臺上(shang)(shang)設置(zhi)的(de)(de)齊心刻度(du)尺和齊心滑塊找(zhao)圓(yuan)、找(zhao)正(zheng)、扭轉磁(ci)力開(kai)關，工(gong)(gong)(gong)(gong)(gong)件(jian)即被緊(jin)緊(jin)吸住。可(ke)(ke)以(yi)一次(ci)性完成端面、鑄(zhu)(zhu)鐵(tie)定(ding)(ding)盤內(nei)圓(yuan)、外(wai)圓(yuan)的(de)(de)車(che)削(xue)。此工(gong)(gong)(gong)(gong)(gong)藝(yi)簡略、快捷、準確、省力，縮短輔(fu)佐任務(wu)工(gong)(gong)(gong)(gong)(gong)夫，進(jin)步任務(wu)效率。圓(yuan)形(xing)任務(wu)臺上(shang)(shang)還裝備了可(ke)(ke)以(yi)拆(chai)開(kai)的(de)(de)導磁(ci)條，鑄(zhu)(zhu)鐵(tie)定(ding)(ding)盤可(ke)(ke)以(yi)在(zai)上(shang)(shang)面加(jia)工(gong)(gong)(gong)(gong)(gong)成一些(xie)固(gu)定(ding)(ding)工(gong)(gong)(gong)(gong)(gong)件(jian)所需(xu)(xu)的(de)(de)非凡工(gong)(gong)(gong)(gong)(gong)裝，知(zhi)足一些(xie)非凡車(che)削(xue)工(gong)(gong)(gong)(gong)(gong)藝(yi)的(de)(de)需(xu)(xu)求。
