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)定盤(pan)(pan)是立式車(che)(che)(che)(che)床裝夾(jia)(jia)工(gong)(gong)(gong)件(jian)(jian)的(de)(de)(de)新型隸屬東西。本來(lai)立式車(che)(che)(che)(che)床只能應用壓(ya)板(ban)螺栓(shuan)和卡鉗(qian)裝夾(jia)(jia)工(gong)(gong)(gong)件(jian)(jian)，車(che)(che)(che)(che)削(xue)(xue)加(jia)(jia)工(gong)(gong)(gong)進(jin)程中反(fan)重復復地(di)裝拆夾(jia)(jia)具，不成(cheng)能一次性完成(cheng)端面(mian)、內圓(yuan)(yuan)、外圓(yuan)(yuan)的(de)(de)(de)車(che)(che)(che)(che)削(xue)(xue)加(jia)(jia)工(gong)(gong)(gong)；還(huan)有些(xie)工(gong)(gong)(gong)件(jian)(jian)別的(de)(de)(de)加(jia)(jia)焊裝夾(jia)(jia)的(de)(de)(de)胎架(jia)(jia)，鑄(zhu)(zhu)鐵(tie)(tie)定盤(pan)(pan)完成(cheng)后(hou)再割除胎架(jia)(jia)，打磨修整，鑄(zhu)(zhu)鐵(tie)(tie)定盤(pan)(pan)尤其有些(xie)壁厚(hou)不大的(de)(de)(de)環形工(gong)(gong)(gong)件(jian)(jian)，假如(ru)用夾(jia)(jia)鉗(qian)固定 會變(bian)形掉圓(yuan)(yuan)，用壓(ya)板(ban)螺栓(shuan)固定，鑄(zhu)(zhu)鐵(tie)(tie)定盤(pan)(pan)工(gong)(gong)(gong)序翻來(lai)覆去很不便利。既(ji)影響加(jia)(jia)工(gong)(gong)(gong)度(du)，鑄(zhu)(zhu)鐵(tie)(tie)定盤(pan)(pan)又操作(zuo)復雜，辛苦(ku)費時。假如(ru)采用圓(yuan)(yuan)形永磁任(ren)(ren)務(wu)臺固定工(gong)(gong)(gong)件(jian)(jian)，鑄(zhu)(zhu)鐵(tie)(tie)定盤(pan)(pan)只須將工(gong)(gong)(gong)件(jian)(jian)放在(zai)圓(yuan)(yuan)臺面(mian)上(shang)，再應用圓(yuan)(yuan)臺上(shang)設置的(de)(de)(de)齊(qi)心刻度(du)尺(chi)和齊(qi)心滑塊找圓(yuan)(yuan)、找正、扭轉磁力(li)開關，工(gong)(gong)(gong)件(jian)(jian)即被緊緊吸住。可以一次性完成(cheng)端面(mian)、鑄(zhu)(zhu)鐵(tie)(tie)定盤(pan)(pan)內圓(yuan)(yuan)、外圓(yuan)(yuan)的(de)(de)(de)車(che)(che)(che)(che)削(xue)(xue)。此(ci)工(gong)(gong)(gong)藝簡略、快捷、準(zhun)確、省力(li)，縮短(duan)輔佐任(ren)(ren)務(wu)工(gong)(gong)(gong)夫，進(jin)步任(ren)(ren)務(wu)效率。圓(yuan)(yuan)形任(ren)(ren)務(wu)臺上(shang)還(huan)裝備了可以拆開的(de)(de)(de)導磁條，鑄(zhu)(zhu)鐵(tie)(tie)定盤(pan)(pan)可以在(zai)上(shang)面(mian)加(jia)(jia)工(gong)(gong)(gong)成(cheng)一些(xie)固定工(gong)(gong)(gong)件(jian)(jian)所(suo)需(xu)的(de)(de)(de)非(fei)凡(fan)工(gong)(gong)(gong)裝，知足一些(xie)非(fei)凡(fan)車(che)(che)(che)(che)削(xue)(xue)工(gong)(gong)(gong)藝的(de)(de)(de)需(xu)求(qiu)。
