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)(tie)(tie)定(ding)(ding)(ding)(ding)(ding)盤(pan)是立式車(che)(che)床裝(zhuang)(zhuang)夾(jia)(jia)工(gong)件的(de)新型隸(li)屬東西。本來立式車(che)(che)床只能(neng)應用(yong)壓(ya)板螺(luo)栓和卡(ka)鉗裝(zhuang)(zhuang)夾(jia)(jia)工(gong)件，車(che)(che)削加(jia)工(gong)進程中反重(zhong)復(fu)復(fu)地裝(zhuang)(zhuang)拆夾(jia)(jia)具，不成(cheng)(cheng)能(neng)一次性(xing)完成(cheng)(cheng)端(duan)面(mian)、內圓(yuan)、外圓(yuan)的(de)車(che)(che)削加(jia)工(gong)；還(huan)有些(xie)工(gong)件別的(de)加(jia)焊(han)裝(zhuang)(zhuang)夾(jia)(jia)的(de)胎架，鑄(zhu)鐵(tie)(tie)(tie)定(ding)(ding)(ding)(ding)(ding)盤(pan)完成(cheng)(cheng)后再割除胎架，打磨(mo)修整，鑄(zhu)鐵(tie)(tie)(tie)定(ding)(ding)(ding)(ding)(ding)盤(pan)尤其有些(xie)壁厚不大的(de)環形(xing)工(gong)件，假如用(yong)夾(jia)(jia)鉗固(gu)(gu)定(ding)(ding)(ding)(ding)(ding) 會變形(xing)掉圓(yuan)，用(yong)壓(ya)板螺(luo)栓固(gu)(gu)定(ding)(ding)(ding)(ding)(ding)，鑄(zhu)鐵(tie)(tie)(tie)定(ding)(ding)(ding)(ding)(ding)盤(pan)工(gong)序翻來覆去(qu)很不便利。既影(ying)響加(jia)工(gong)度(du)，鑄(zhu)鐵(tie)(tie)(tie)定(ding)(ding)(ding)(ding)(ding)盤(pan)又(you)操作復(fu)雜(za)，辛(xin)苦費(fei)時(shi)。假如采用(yong)圓(yuan)形(xing)永磁(ci)任(ren)務(wu)臺(tai)固(gu)(gu)定(ding)(ding)(ding)(ding)(ding)工(gong)件，鑄(zhu)鐵(tie)(tie)(tie)定(ding)(ding)(ding)(ding)(ding)盤(pan)只須將工(gong)件放在圓(yuan)臺(tai)面(mian)上，再應用(yong)圓(yuan)臺(tai)上設(she)置的(de)齊心(xin)刻度(du)尺和齊心(xin)滑塊找圓(yuan)、找正、扭轉磁(ci)力開關，工(gong)件即被緊緊吸(xi)住。可以一次性(xing)完成(cheng)(cheng)端(duan)面(mian)、鑄(zhu)鐵(tie)(tie)(tie)定(ding)(ding)(ding)(ding)(ding)盤(pan)內圓(yuan)、外圓(yuan)的(de)車(che)(che)削。此工(gong)藝簡略、快捷、準確、省力，縮(suo)短輔(fu)佐(zuo)任(ren)務(wu)工(gong)夫，進步任(ren)務(wu)效率。圓(yuan)形(xing)任(ren)務(wu)臺(tai)上還(huan)裝(zhuang)(zhuang)備了(le)可以拆開的(de)導磁(ci)條，鑄(zhu)鐵(tie)(tie)(tie)定(ding)(ding)(ding)(ding)(ding)盤(pan)可以在上面(mian)加(jia)工(gong)成(cheng)(cheng)一些(xie)固(gu)(gu)定(ding)(ding)(ding)(ding)(ding)工(gong)件所(suo)需的(de)非凡(fan)工(gong)裝(zhuang)(zhuang)，知(zhi)足一些(xie)非凡(fan)車(che)(che)削工(gong)藝的(de)需求(qiu)。
