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)(tie)定(ding)(ding)盤(pan)(pan)是(shi)立(li)(li)式車(che)床裝(zhuang)夾(jia)(jia)(jia)工(gong)(gong)(gong)件(jian)(jian)的(de)(de)新型(xing)隸屬東西。本(ben)來立(li)(li)式車(che)床只能應用(yong)壓板螺(luo)栓和卡鉗(qian)裝(zhuang)夾(jia)(jia)(jia)工(gong)(gong)(gong)件(jian)(jian)，車(che)削(xue)加(jia)(jia)工(gong)(gong)(gong)進程中(zhong)反(fan)重(zhong)復(fu)復(fu)地裝(zhuang)拆夾(jia)(jia)(jia)具，不(bu)成(cheng)能一次性完成(cheng)端面、內(nei)圓(yuan)、外圓(yuan)的(de)(de)車(che)削(xue)加(jia)(jia)工(gong)(gong)(gong)；還(huan)有些(xie)工(gong)(gong)(gong)件(jian)(jian)別的(de)(de)加(jia)(jia)焊裝(zhuang)夾(jia)(jia)(jia)的(de)(de)胎架，鑄(zhu)(zhu)鐵(tie)(tie)定(ding)(ding)盤(pan)(pan)完成(cheng)后再割除(chu)胎架，打磨修(xiu)整，鑄(zhu)(zhu)鐵(tie)(tie)定(ding)(ding)盤(pan)(pan)尤其(qi)有些(xie)壁厚不(bu)大(da)的(de)(de)環形工(gong)(gong)(gong)件(jian)(jian)，假(jia)如用(yong)夾(jia)(jia)(jia)鉗(qian)固定(ding)(ding) 會變形掉(diao)圓(yuan)，用(yong)壓板螺(luo)栓固定(ding)(ding)，鑄(zhu)(zhu)鐵(tie)(tie)定(ding)(ding)盤(pan)(pan)工(gong)(gong)(gong)序翻來覆去很不(bu)便利。既影響加(jia)(jia)工(gong)(gong)(gong)度，鑄(zhu)(zhu)鐵(tie)(tie)定(ding)(ding)盤(pan)(pan)又操作(zuo)復(fu)雜，辛苦費時。假(jia)如采用(yong)圓(yuan)形永磁(ci)任(ren)(ren)務(wu)臺(tai)固定(ding)(ding)工(gong)(gong)(gong)件(jian)(jian)，鑄(zhu)(zhu)鐵(tie)(tie)定(ding)(ding)盤(pan)(pan)只須將工(gong)(gong)(gong)件(jian)(jian)放在圓(yuan)臺(tai)面上，再應用(yong)圓(yuan)臺(tai)上設(she)置的(de)(de)齊心(xin)刻度尺(chi)和齊心(xin)滑塊找(zhao)圓(yuan)、找(zhao)正、扭轉磁(ci)力開關，工(gong)(gong)(gong)件(jian)(jian)即被緊(jin)緊(jin)吸住。可(ke)以一次性完成(cheng)端面、鑄(zhu)(zhu)鐵(tie)(tie)定(ding)(ding)盤(pan)(pan)內(nei)圓(yuan)、外圓(yuan)的(de)(de)車(che)削(xue)。此工(gong)(gong)(gong)藝簡略、快(kuai)捷、準確、省力，縮短輔佐(zuo)任(ren)(ren)務(wu)工(gong)(gong)(gong)夫，進步任(ren)(ren)務(wu)效率。圓(yuan)形任(ren)(ren)務(wu)臺(tai)上還(huan)裝(zhuang)備了可(ke)以拆開的(de)(de)導磁(ci)條，鑄(zhu)(zhu)鐵(tie)(tie)定(ding)(ding)盤(pan)(pan)可(ke)以在上面加(jia)(jia)工(gong)(gong)(gong)成(cheng)一些(xie)固定(ding)(ding)工(gong)(gong)(gong)件(jian)(jian)所需(xu)(xu)的(de)(de)非凡工(gong)(gong)(gong)裝(zhuang)，知足一些(xie)非凡車(che)削(xue)工(gong)(gong)(gong)藝的(de)(de)需(xu)(xu)求。
