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)鐵定(ding)盤(pan)是立(li)(li)式(shi)車床裝(zhuang)夾(jia)工(gong)(gong)(gong)件(jian)的(de)(de)(de)(de)新型隸屬東西(xi)。本(ben)來立(li)(li)式(shi)車床只(zhi)能應用(yong)(yong)壓板(ban)螺(luo)栓和(he)卡鉗裝(zhuang)夾(jia)工(gong)(gong)(gong)件(jian)，車削加工(gong)(gong)(gong)進程(cheng)中(zhong)反重復復地裝(zhuang)拆(chai)夾(jia)具，不成(cheng)能一(yi)次性完成(cheng)端面、內圓(yuan)、外圓(yuan)的(de)(de)(de)(de)車削加工(gong)(gong)(gong)；還有些(xie)(xie)(xie)工(gong)(gong)(gong)件(jian)別(bie)的(de)(de)(de)(de)加焊裝(zhuang)夾(jia)的(de)(de)(de)(de)胎架(jia)，鑄(zhu)(zhu)鐵定(ding)盤(pan)完成(cheng)后再(zai)割(ge)除胎架(jia)，打(da)磨(mo)修(xiu)整，鑄(zhu)(zhu)鐵定(ding)盤(pan)尤其有些(xie)(xie)(xie)壁(bi)厚不大的(de)(de)(de)(de)環形(xing)(xing)工(gong)(gong)(gong)件(jian)，假如(ru)用(yong)(yong)夾(jia)鉗固(gu)定(ding) 會變(bian)形(xing)(xing)掉圓(yuan)，用(yong)(yong)壓板(ban)螺(luo)栓固(gu)定(ding)，鑄(zhu)(zhu)鐵定(ding)盤(pan)工(gong)(gong)(gong)序(xu)翻來覆去很不便利。既影響加工(gong)(gong)(gong)度(du)，鑄(zhu)(zhu)鐵定(ding)盤(pan)又操作復雜，辛苦(ku)費(fei)時。假如(ru)采用(yong)(yong)圓(yuan)形(xing)(xing)永磁任(ren)務(wu)臺(tai)固(gu)定(ding)工(gong)(gong)(gong)件(jian)，鑄(zhu)(zhu)鐵定(ding)盤(pan)只(zhi)須(xu)將(jiang)工(gong)(gong)(gong)件(jian)放在(zai)圓(yuan)臺(tai)面上(shang)，再(zai)應用(yong)(yong)圓(yuan)臺(tai)上(shang)設(she)置(zhi)的(de)(de)(de)(de)齊心(xin)(xin)刻度(du)尺和(he)齊心(xin)(xin)滑塊找(zhao)圓(yuan)、找(zhao)正(zheng)、扭(niu)轉磁力開關，工(gong)(gong)(gong)件(jian)即被緊(jin)緊(jin)吸住。可(ke)(ke)以一(yi)次性完成(cheng)端面、鑄(zhu)(zhu)鐵定(ding)盤(pan)內圓(yuan)、外圓(yuan)的(de)(de)(de)(de)車削。此工(gong)(gong)(gong)藝(yi)簡略(lve)、快捷、準確、省力，縮短輔(fu)佐任(ren)務(wu)工(gong)(gong)(gong)夫，進步任(ren)務(wu)效(xiao)率。圓(yuan)形(xing)(xing)任(ren)務(wu)臺(tai)上(shang)還裝(zhuang)備了(le)可(ke)(ke)以拆(chai)開的(de)(de)(de)(de)導(dao)磁條，鑄(zhu)(zhu)鐵定(ding)盤(pan)可(ke)(ke)以在(zai)上(shang)面加工(gong)(gong)(gong)成(cheng)一(yi)些(xie)(xie)(xie)固(gu)定(ding)工(gong)(gong)(gong)件(jian)所需的(de)(de)(de)(de)非凡工(gong)(gong)(gong)裝(zhuang)，知(zhi)足一(yi)些(xie)(xie)(xie)非凡車削工(gong)(gong)(gong)藝(yi)的(de)(de)(de)(de)需求。
