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)定(ding)盤(pan)(pan)(pan)是立式(shi)車(che)床裝(zhuang)(zhuang)夾工(gong)(gong)(gong)(gong)件(jian)的(de)新型隸屬東(dong)西(xi)。本來立式(shi)車(che)床只能應用壓板螺栓和(he)卡鉗(qian)裝(zhuang)(zhuang)夾工(gong)(gong)(gong)(gong)件(jian)，車(che)削加工(gong)(gong)(gong)(gong)進程中(zhong)反重復(fu)復(fu)地裝(zhuang)(zhuang)拆(chai)夾具，不(bu)成能一(yi)(yi)次性完成端(duan)面(mian)、內(nei)圓(yuan)(yuan)、外圓(yuan)(yuan)的(de)車(che)削加工(gong)(gong)(gong)(gong)；還(huan)有些工(gong)(gong)(gong)(gong)件(jian)別的(de)加焊裝(zhuang)(zhuang)夾的(de)胎(tai)架(jia)，鑄(zhu)鐵(tie)(tie)定(ding)盤(pan)(pan)(pan)完成后再割除胎(tai)架(jia)，打磨修整，鑄(zhu)鐵(tie)(tie)定(ding)盤(pan)(pan)(pan)尤其有些壁厚(hou)不(bu)大的(de)環(huan)形(xing)(xing)工(gong)(gong)(gong)(gong)件(jian)，假(jia)如(ru)用夾鉗(qian)固定(ding) 會變形(xing)(xing)掉圓(yuan)(yuan)，用壓板螺栓固定(ding)，鑄(zhu)鐵(tie)(tie)定(ding)盤(pan)(pan)(pan)工(gong)(gong)(gong)(gong)序翻(fan)來覆去很不(bu)便利。既影響加工(gong)(gong)(gong)(gong)度，鑄(zhu)鐵(tie)(tie)定(ding)盤(pan)(pan)(pan)又操作復(fu)雜，辛苦費時。假(jia)如(ru)采(cai)用圓(yuan)(yuan)形(xing)(xing)永磁任務(wu)臺(tai)固定(ding)工(gong)(gong)(gong)(gong)件(jian)，鑄(zhu)鐵(tie)(tie)定(ding)盤(pan)(pan)(pan)只須將工(gong)(gong)(gong)(gong)件(jian)放在圓(yuan)(yuan)臺(tai)面(mian)上，再應用圓(yuan)(yuan)臺(tai)上設置的(de)齊(qi)心刻(ke)度尺和(he)齊(qi)心滑塊找圓(yuan)(yuan)、找正、扭轉磁力開關(guan)，工(gong)(gong)(gong)(gong)件(jian)即被緊緊吸住。可(ke)以一(yi)(yi)次性完成端(duan)面(mian)、鑄(zhu)鐵(tie)(tie)定(ding)盤(pan)(pan)(pan)內(nei)圓(yuan)(yuan)、外圓(yuan)(yuan)的(de)車(che)削。此工(gong)(gong)(gong)(gong)藝(yi)簡略(lve)、快捷(jie)、準確、省力，縮短輔佐任務(wu)工(gong)(gong)(gong)(gong)夫，進步任務(wu)效率。圓(yuan)(yuan)形(xing)(xing)任務(wu)臺(tai)上還(huan)裝(zhuang)(zhuang)備(bei)了可(ke)以拆(chai)開的(de)導磁條，鑄(zhu)鐵(tie)(tie)定(ding)盤(pan)(pan)(pan)可(ke)以在上面(mian)加工(gong)(gong)(gong)(gong)成一(yi)(yi)些固定(ding)工(gong)(gong)(gong)(gong)件(jian)所需(xu)的(de)非(fei)凡(fan)工(gong)(gong)(gong)(gong)裝(zhuang)(zhuang)，知足一(yi)(yi)些非(fei)凡(fan)車(che)削工(gong)(gong)(gong)(gong)藝(yi)的(de)需(xu)求。
