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。
鑄鐵(tie)(tie)定(ding)(ding)(ding)盤是立式(shi)車(che)(che)(che)床裝(zhuang)(zhuang)夾工(gong)(gong)(gong)件(jian)的(de)(de)新(xin)型隸屬東西(xi)。本來(lai)立式(shi)車(che)(che)(che)床只能(neng)應(ying)用壓板(ban)螺(luo)栓和(he)卡鉗裝(zhuang)(zhuang)夾工(gong)(gong)(gong)件(jian)，車(che)(che)(che)削加(jia)(jia)工(gong)(gong)(gong)進程(cheng)中反重復復地裝(zhuang)(zhuang)拆(chai)夾具，不(bu)成能(neng)一次(ci)性完成端(duan)面、內圓(yuan)(yuan)、外圓(yuan)(yuan)的(de)(de)車(che)(che)(che)削加(jia)(jia)工(gong)(gong)(gong)；還(huan)有些(xie)工(gong)(gong)(gong)件(jian)別的(de)(de)加(jia)(jia)焊(han)裝(zhuang)(zhuang)夾的(de)(de)胎(tai)架，鑄鐵(tie)(tie)定(ding)(ding)(ding)盤完成后再割除胎(tai)架，打(da)磨修(xiu)整，鑄鐵(tie)(tie)定(ding)(ding)(ding)盤尤其有些(xie)壁厚不(bu)大的(de)(de)環形(xing)工(gong)(gong)(gong)件(jian)，假如(ru)用夾鉗固(gu)(gu)定(ding)(ding)(ding) 會變形(xing)掉圓(yuan)(yuan)，用壓板(ban)螺(luo)栓固(gu)(gu)定(ding)(ding)(ding)，鑄鐵(tie)(tie)定(ding)(ding)(ding)盤工(gong)(gong)(gong)序翻(fan)來(lai)覆去(qu)很不(bu)便利。既影(ying)響加(jia)(jia)工(gong)(gong)(gong)度，鑄鐵(tie)(tie)定(ding)(ding)(ding)盤又操作復雜，辛苦費時。假如(ru)采(cai)用圓(yuan)(yuan)形(xing)永(yong)磁任務(wu)(wu)(wu)臺固(gu)(gu)定(ding)(ding)(ding)工(gong)(gong)(gong)件(jian)，鑄鐵(tie)(tie)定(ding)(ding)(ding)盤只須(xu)將工(gong)(gong)(gong)件(jian)放在(zai)圓(yuan)(yuan)臺面上(shang)，再應(ying)用圓(yuan)(yuan)臺上(shang)設置的(de)(de)齊(qi)心刻度尺(chi)和(he)齊(qi)心滑塊找(zhao)(zhao)圓(yuan)(yuan)、找(zhao)(zhao)正、扭轉磁力開關，工(gong)(gong)(gong)件(jian)即被緊(jin)緊(jin)吸住。可(ke)(ke)以(yi)(yi)一次(ci)性完成端(duan)面、鑄鐵(tie)(tie)定(ding)(ding)(ding)盤內圓(yuan)(yuan)、外圓(yuan)(yuan)的(de)(de)車(che)(che)(che)削。此工(gong)(gong)(gong)藝簡略、快捷(jie)、準確、省力，縮短輔佐任務(wu)(wu)(wu)工(gong)(gong)(gong)夫(fu)，進步任務(wu)(wu)(wu)效率。圓(yuan)(yuan)形(xing)任務(wu)(wu)(wu)臺上(shang)還(huan)裝(zhuang)(zhuang)備了可(ke)(ke)以(yi)(yi)拆(chai)開的(de)(de)導磁條，鑄鐵(tie)(tie)定(ding)(ding)(ding)盤可(ke)(ke)以(yi)(yi)在(zai)上(shang)面加(jia)(jia)工(gong)(gong)(gong)成一些(xie)固(gu)(gu)定(ding)(ding)(ding)工(gong)(gong)(gong)件(jian)所需(xu)的(de)(de)非凡(fan)工(gong)(gong)(gong)裝(zhuang)(zhuang)，知(zhi)足(zu)一些(xie)非凡(fan)車(che)(che)(che)削工(gong)(gong)(gong)藝的(de)(de)需(xu)求。
