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)(ding)盤是立(li)式(shi)車(che)床(chuang)(chuang)裝(zhuang)(zhuang)(zhuang)夾(jia)(jia)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)的(de)(de)新型隸屬(shu)東西。本來(lai)立(li)式(shi)車(che)床(chuang)(chuang)只(zhi)能應用壓板(ban)螺栓和卡鉗裝(zhuang)(zhuang)(zhuang)夾(jia)(jia)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)，車(che)削加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)進程(cheng)中反重復(fu)復(fu)地裝(zhuang)(zhuang)(zhuang)拆夾(jia)(jia)具，不成(cheng)能一(yi)次性(xing)(xing)完成(cheng)端(duan)面(mian)(mian)、內(nei)圓(yuan)(yuan)(yuan)、外(wai)圓(yuan)(yuan)(yuan)的(de)(de)車(che)削加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)；還有些(xie)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)別的(de)(de)加(jia)(jia)(jia)(jia)焊裝(zhuang)(zhuang)(zhuang)夾(jia)(jia)的(de)(de)胎架，鑄(zhu)鐵(tie)(tie)定(ding)(ding)盤完成(cheng)后(hou)再割除(chu)胎架，打磨修整，鑄(zhu)鐵(tie)(tie)定(ding)(ding)盤尤(you)其有些(xie)壁厚不大的(de)(de)環形(xing)(xing)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)，假如用夾(jia)(jia)鉗固定(ding)(ding) 會變形(xing)(xing)掉圓(yuan)(yuan)(yuan)，用壓板(ban)螺栓固定(ding)(ding)，鑄(zhu)鐵(tie)(tie)定(ding)(ding)盤工(gong)(gong)(gong)(gong)(gong)序翻(fan)來(lai)覆(fu)去(qu)很不便利。既影(ying)響加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)度(du)，鑄(zhu)鐵(tie)(tie)定(ding)(ding)盤又操作(zuo)復(fu)雜(za)，辛苦費時。假如采用圓(yuan)(yuan)(yuan)形(xing)(xing)永磁(ci)任務臺(tai)固定(ding)(ding)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)，鑄(zhu)鐵(tie)(tie)定(ding)(ding)盤只(zhi)須將工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)放在(zai)圓(yuan)(yuan)(yuan)臺(tai)面(mian)(mian)上(shang)，再應用圓(yuan)(yuan)(yuan)臺(tai)上(shang)設置(zhi)的(de)(de)齊(qi)心(xin)(xin)刻度(du)尺和齊(qi)心(xin)(xin)滑塊找圓(yuan)(yuan)(yuan)、找正(zheng)、扭(niu)轉磁(ci)力開關，工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)即被緊(jin)緊(jin)吸住。可(ke)以(yi)(yi)一(yi)次性(xing)(xing)完成(cheng)端(duan)面(mian)(mian)、鑄(zhu)鐵(tie)(tie)定(ding)(ding)盤內(nei)圓(yuan)(yuan)(yuan)、外(wai)圓(yuan)(yuan)(yuan)的(de)(de)車(che)削。此工(gong)(gong)(gong)(gong)(gong)藝簡略(lve)、快(kuai)捷、準確、省力，縮短(duan)輔(fu)佐任務工(gong)(gong)(gong)(gong)(gong)夫，進步任務效率(lv)。圓(yuan)(yuan)(yuan)形(xing)(xing)任務臺(tai)上(shang)還裝(zhuang)(zhuang)(zhuang)備(bei)了可(ke)以(yi)(yi)拆開的(de)(de)導磁(ci)條，鑄(zhu)鐵(tie)(tie)定(ding)(ding)盤可(ke)以(yi)(yi)在(zai)上(shang)面(mian)(mian)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)成(cheng)一(yi)些(xie)固定(ding)(ding)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)所需(xu)的(de)(de)非凡(fan)工(gong)(gong)(gong)(gong)(gong)裝(zhuang)(zhuang)(zhuang)，知足一(yi)些(xie)非凡(fan)車(che)削工(gong)(gong)(gong)(gong)(gong)藝的(de)(de)需(xu)求。
