零件加工中心的刀具你是怎么選擇的?

在CNC編程(cheng)的人機(ji)交互狀態下進行(xing)工(gong)(gong)(gong)具(ju)選(xuan)擇(ze)。根據(ju)機(ji)床(chuang)的加(jia)工(gong)(gong)(gong)能力(li)，工(gong)(gong)(gong)件材料的性能，加(jia)工(gong)(gong)(gong)程(cheng)序(xu)，切削參(can)數(shu)等相(xiang)關因(yin)素，應(ying)正確(que)(que)選(xuan)擇(ze)刀具(ju)和(he)刀柄(bing)。在nc編程(cheng)的人機(ji)交互狀態下進行(xing)工(gong)(gong)(gong)具(ju)選(xuan)擇(ze)。根據(ju)機(ji)床(chuang)的加(jia)工(gong)(gong)(gong)能力(li)，工(gong)(gong)(gong)件材料的性能，加(jia)工(gong)(gong)(gong)程(cheng)序(xu)，切削參(can)數(shu)等相(xiang)關因(yin)素，應(ying)正確(que)(que)選(xuan)擇(ze)刀具(ju)和(he)刀柄(bing)。

CNC零件加工中心廠(chang)家選(xuan)擇(ze)(ze)工具(ju)(ju)的一(yi)般(ban)原(yuan)則是：易于安裝和調(diao)整，剛(gang)性(xing)好，耐(nai)用性(xing)高(gao)(gao)和精(jing)度高(gao)(gao)。在滿足加(jia)工要求的前提下，盡量選(xuan)擇(ze)(ze)較短的手柄，以提高(gao)(gao)加(jia)工刀具(ju)(ju)的剛(gang)性(xing)。

選(xuan)擇(ze)工(gong)具時(shi)，使(shi)工(gong)具的(de)(de)(de)(de)尺(chi)寸適合(he)被加(jia)工(gong)工(gong)件的(de)(de)(de)(de)表面尺(chi)寸。在生(sheng)產(chan)中，平(ping)面零(ling)件周(zhou)圍(wei)的(de)(de)(de)(de)輪廓(kuo)加(jia)工(gong)時(shi)，常使(shi)用立銑(xian)(xian)刀(dao)；銑(xian)(xian)刨(bao)平(ping)面時(shi)，應選(xuan)擇(ze)硬(ying)質合(he)金(jin)刀(dao)具；加(jia)工(gong)凸臺，坡(po)口，選(xuan)擇(ze)高速(su)鋼立銑(xian)(xian)刀(dao)；在加(jia)工(gong)毛(mao)坯表面或粗(cu)糙(cao)的(de)(de)(de)(de)加(jia)工(gong)孔時(shi)，可以(yi)選(xuan)擇(ze)帶有硬(ying)質合(he)金(jin)刀(dao)片的(de)(de)(de)(de)玉米銑(xian)(xian)刀(dao)。為(wei)了加(jia)工(gong)某(mou)些(xie)垂直的(de)(de)(de)(de)車(che)身表面和(he)可變(bian)的(de)(de)(de)(de)坡(po)口輪廓(kuo)，經(jing)常使(shi)用球(qiu)磨(mo)刀(dao)，環形銑(xian)(xian)刀(dao)，錐形銑(xian)(xian)刀(dao)和(he)盤式銑(xian)(xian)刀(dao)。

在自由(you)曲面(mian)(mian)加(jia)(jia)(jia)(jia)工(gong)(gong)過程中，由(you)于球頭工(gong)(gong)具(ju)(ju)端(duan)部的(de)(de)(de)(de)切(qie)(qie)割(ge)速度(du)為(wei)(wei)零，因(yin)此(ci)，為(wei)(wei)了保證(zheng)加(jia)(jia)(jia)(jia)工(gong)(gong)精度(du)，切(qie)(qie)割(ge)線間距通(tong)常非常密，因(yin)此(ci)球頭經(jing)常用于表面(mian)(mian)處理。并(bing)且該平面(mian)(mian)工(gong)(gong)具(ju)(ju)在表面(mian)(mian)加(jia)(jia)(jia)(jia)工(gong)(gong)質(zhi)量(liang)和切(qie)(qie)削效(xiao)率(lv)(lv)上均優于球形工(gong)(gong)具(ju)(ju)，因(yin)此(ci)，在確保不切(qie)(qie)削的(de)(de)(de)(de)前提(ti)下，無論是對表面(mian)(mian)進行(xing)粗(cu)加(jia)(jia)(jia)(jia)工(gong)(gong)還是精加(jia)(jia)(jia)(jia)工(gong)(gong)，都(dou)應選擇平面(mian)(mian)工(gong)(gong)具(ju)(ju)。另外，刀具(ju)(ju)的(de)(de)(de)(de)耐(nai)用性和精度(du)與刀具(ju)(ju)價格的(de)(de)(de)(de)關系非常大，必須(xu)注(zhu)意的(de)(de)(de)(de)是，在大多數情況下，盡管(guan)選擇優質(zhi)的(de)(de)(de)(de)刀具(ju)(ju)會增加(jia)(jia)(jia)(jia)刀具(ju)(ju)成(cheng)本(ben)，但由(you)此(ci)導(dao)致加(jia)(jia)(jia)(jia)工(gong)(gong)質(zhi)量(liang)和加(jia)(jia)(jia)(jia)工(gong)(gong)效(xiao)率(lv)(lv)的(de)(de)(de)(de)提(ti)高。加(jia)(jia)(jia)(jia)工(gong)(gong)效(xiao)率(lv)(lv)高，可以使整個加(jia)(jia)(jia)(jia)工(gong)(gong)成(cheng)本(ben)大大降(jiang)低。

在CNC零件加工中心廠家，各種(zhong)工(gong)(gong)(gong)(gong)具(ju)均安裝在(zai)工(gong)(gong)(gong)(gong)具(ju)庫中，可根據(ju)程序隨(sui)時選擇(ze)和更改切刀動作。因此(ci)必須使用(yong)(yong)標準(zhun)工(gong)(gong)(gong)(gong)具(ju)手(shou)柄，以(yi)便(bian)用(yong)(yong)標準(zhun)工(gong)(gong)(gong)(gong)具(ju)進行鉆孔，鏜孔，擴(kuo)展，銑(xian)削等程序，快速，準(zhun)確地安裝在(zai)機床主軸或工(gong)(gong)(gong)(gong)具(ju)庫上的程序員應該(gai)了解工(gong)(gong)(gong)(gong)具(ju)手(shou)柄上使用(yong)(yong)的工(gong)(gong)(gong)(gong)具(ju)接頭尺寸，調(diao)節方法和調(diao)節范(fan)圍，以(yi)便(bian)在(zai)編程時確定刀具(ju)的徑向和軸向尺寸。
