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)定(ding)(ding)盤(pan)是立式車床裝夾(jia)工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)的(de)(de)新型隸屬東西。本來立式車床只能應用壓板螺栓(shuan)和卡鉗裝夾(jia)工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)，車削加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)進(jin)程中反重(zhong)復復地裝拆夾(jia)具，不(bu)(bu)成能一(yi)次(ci)性完(wan)成端面、內(nei)圓(yuan)、外(wai)圓(yuan)的(de)(de)車削加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)；還(huan)有些(xie)工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)別的(de)(de)加(jia)(jia)(jia)(jia)焊裝夾(jia)的(de)(de)胎架，鑄(zhu)鐵(tie)定(ding)(ding)盤(pan)完(wan)成后再割除胎架，打磨修整(zheng)，鑄(zhu)鐵(tie)定(ding)(ding)盤(pan)尤(you)其(qi)有些(xie)壁厚不(bu)(bu)大的(de)(de)環形工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)，假(jia)如(ru)(ru)用夾(jia)鉗固定(ding)(ding) 會變形掉圓(yuan)，用壓板螺栓(shuan)固定(ding)(ding)，鑄(zhu)鐵(tie)定(ding)(ding)盤(pan)工(gong)(gong)(gong)(gong)序翻來覆去很(hen)不(bu)(bu)便利。既影(ying)響加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)度，鑄(zhu)鐵(tie)定(ding)(ding)盤(pan)又操作復雜，辛(xin)苦費時。假(jia)如(ru)(ru)采(cai)用圓(yuan)形永(yong)磁(ci)任(ren)務臺固定(ding)(ding)工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)，鑄(zhu)鐵(tie)定(ding)(ding)盤(pan)只須(xu)將(jiang)工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)放(fang)在圓(yuan)臺面上(shang)(shang)，再應用圓(yuan)臺上(shang)(shang)設置的(de)(de)齊(qi)心(xin)刻度尺和齊(qi)心(xin)滑塊找圓(yuan)、找正、扭轉(zhuan)磁(ci)力(li)開(kai)關，工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)即被緊(jin)緊(jin)吸住。可(ke)以一(yi)次(ci)性完(wan)成端面、鑄(zhu)鐵(tie)定(ding)(ding)盤(pan)內(nei)圓(yuan)、外(wai)圓(yuan)的(de)(de)車削。此工(gong)(gong)(gong)(gong)藝(yi)(yi)簡略、快捷、準確、省力(li)，縮短輔佐任(ren)務工(gong)(gong)(gong)(gong)夫，進(jin)步任(ren)務效率。圓(yuan)形任(ren)務臺上(shang)(shang)還(huan)裝備了(le)可(ke)以拆開(kai)的(de)(de)導磁(ci)條，鑄(zhu)鐵(tie)定(ding)(ding)盤(pan)可(ke)以在上(shang)(shang)面加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)成一(yi)些(xie)固定(ding)(ding)工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)所需(xu)的(de)(de)非凡工(gong)(gong)(gong)(gong)裝，知足(zu)一(yi)些(xie)非凡車削工(gong)(gong)(gong)(gong)藝(yi)(yi)的(de)(de)需(xu)求。
