從數(shu)控(kong)銑(xian)床(chuang)(chuang)操(cao)作到加(jia)工(gong)中(zhong)心(xin)操(cao)作的(de)思路(lu),從簡單到復雜,精(jing)心(xin)設(she)計了六個(ge)項(xiang)(xiang)目七個(ge)真實零件的(de)生產加(jia)工(gong).通過循序漸進(jin)的(de)項(xiang)(xiang)目實施教學,使(shi)學生在(zai)完成所(suo)有零件加(jia)工(gong)的(de)過程中(zhong),掌握數(shu)控(kong)銑(xian)床(chuang)(chuang),加(jia)工(gong)中(zhong)心(xin)加(jia)工(gong)所(suo)必需的(de)工(gong)藝(yi),編(bian)程,操(cao)作知(zhi)識,具備(bei)良好的(de)數(shu)控(kong)銑(xian)床(chuang)(chuang),加(jia)工(gong)中(zhong)心(xin)操(cao)作職(zhi)業技能及職(zhi)業素質.
數(shu)控(kong)銑床(chuang)是一種(zhong)能(neng)夠(gou)對工(gong)件(jian)在(zai)一定的(de)范圍(wei)內進行多種(zhong)加工(gong)操作(zuo)的(de)數(shu)控(kong)機(ji)床(chuang),品(pin)質好的(de)數(shu)控(kong)銑床(chuang)能(neng)集中地、自動(dong)地完成多種(zhong)工(gong)序,避免了(le)人為的(de)操作(zuo)誤(wu)差(cha)、減(jian)少(shao)了(le)工(gong)件(jian)裝夾、測量和機(ji)床(chuang)的(de)調整時間。那么(me)本期(qi)小編就為大(da)家(jia)介紹一下數(shu)控(kong)銑床(chuang)的(de)重要(yao)操作(zuo)步驟(zou),以免在(zai)工(gong)作(zuo)中出現意外。
第(di)一、準備工作
打開總電源、機(ji)床(chuang)電源、機(ji)床(chuang)系(xi)統開關、緊(jin)急停(ting)止按(an)鈕(niu)和電腦,然后接收(shou)(shou)加(jia)(jia)(jia)工程(cheng)式單和工件(jian),從組長那里(li)接收(shou)(shou)加(jia)(jia)(jia)工加(jia)(jia)(jia)工程(cheng)式單和相(xiang)對應的加(jia)(jia)(jia)工零(ling)件(jian)。數(shu)控銑(xian)床(chuang)在接收(shou)(shou)時(shi),一定要清楚地知道本(ben)零(ling)件(jian)的加(jia)(jia)(jia)工位(wei)置(zhi)、及(ji)加(jia)(jia)(jia)工方(fang)法,重點部(bu)位(wei)要寫加(jia)(jia)(jia)工指示(shi)。
第二(er)、校正分中
校(xiao)正數(shu)控銑床時,將接收工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)按正確的加工(gong)(gong)(gong)方法排放在(zai)已擦干(gan)凈(jing)的機(ji)床工(gong)(gong)(gong)作(zuo)臺上(shang),并將加工(gong)(gong)(gong)零(ling)件(jian)(jian)(jian)(jian)按所(suo)對應(ying)的方向(xiang)裝工(gong)(gong)(gong)件(jian)(jian)(jian)(jian),然后(hou)校(xiao)正分中,校(xiao)正時要注(zhu)意檢(jian)查(cha)工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)平面是(shi)(shi)否(fou)平行垂直,工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)移(yi)動(dong)行程是(shi)(shi)否(fou)夠位,工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)方向(xiang)是(shi)(shi)否(fou)與(yu)工(gong)(gong)(gong)作(zuo)圖(tu)面相(xiang)對應(ying),校(xiao)正工(gong)(gong)(gong)作(zuo)結束(shu)后(hou)注(zhu)意鎖緊(jin)工(gong)(gong)(gong)件(jian)(jian)(jian)(jian),鎖緊(jin)工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)后(hou)要在(zai)檢(jian)查(cha)一(yi)遍,看工(gong)(gong)(gong)件(jian)(jian)(jian)(jian)在(zai)鎖緊(jin)過程中是(shi)(shi)否(fou)有變(bian)動(dong)。
第三、裝刀(dao)及(ji)收尾工作 在(zai)裝刀(dao)的(de)時候要(yao)(yao)注意(yi)必須看清楚(chu)程式單的(de)刀(dao)具(ju)(ju)長(chang)度,保證(zheng)刀(dao)具(ju)(ju)夠長(chang)。一定要(yao)(yao)將刀(dao)頭吹干(gan)凈,檢查刀(dao)具(ju)(ju)是否完好(hao)。對(dui)刀(dao)時注意(yi)對(dui)刀(dao)要(yao)(yao)注意(yi)在(zai)同一位(wei)置對(dui)刀(dao),保證(zheng)每把(ba)刀(dao)對(dui)準,對(dui)刀(dao)時注意(yi)不(bu)要(yao)(yao)碰壞(huai)刀(dao)尖。加(jia)工結束后,盡可能將放(fang)電部分(fen)(fen)的(de)尺(chi)寸用(yong)量具(ju)(ju)(卡尺(chi)、外徑千分(fen)(fen)尺(chi)、校表)檢測一遍。因為數控銑床質量要(yao)(yao)求(qiu)百分(fen)(fen)之百保證(zheng),所以要(yao)(yao)預(yu)防下次使(shi)用(yong)時刀(dao)具(ju)(ju)尺(chi)寸不(bu)到位(wei),尺(chi)寸超(chao)差(cha)等誤差(cha)的(de)出現。
現代數控銑床的發展趨向是高可靠性、高精度化、高速化、復合化、多功能、智能化和開放式結構。高質量的數控銑床是機械加工自動化的基礎,是數控機床的核心技術,其水平高低關系到國家戰略地位和體現國家綜合實力的水平。它隨著信息技術、微電子技術、自動化技術和檢測技術的發展而發展。消費者要保證在使用數控銑床工作時嚴格遵守操作步驟,盡量不要因為個人技術上的問題出現安全事故 //xcmag.cn/
