重(zhong)型龍門(men)刨銑床(chuang)本身質量(liang)的(de)(de)(de)優(you)劣，直接影響(xiang)所造(zao)機器的(de)(de)(de)質量(liang)。衡量(liang)一臺機床(chuang)的(de)(de)(de)質量(liang)是(shi)多方面(mian)的(de)(de)(de)，但主(zhu)要是(shi)要求工藝性好，系列化，通(tong)用化，標(biao)準化程(cheng)度高，結構簡單，重(zhong)量(liang)輕，工作可靠，生產率高等。我(wo)公(gong)司生產的(de)(de)(de)重(zhong)型龍門(men)刨銑床(chuang)具有(you)門(men)式框架和臥(wo)式長床(chuang)身的(de)(de)(de)刨床(chuang)。

　　重(zhong)型龍(long)門(men)刨(bao)銑(xian)床主要用于刨(bao)削大型工(gong)件(jian)，也可(ke)(ke)在工(gong)作(zuo)臺上(shang)(shang)(shang)裝夾多個零件(jian)同時加工(gong)，是工(gong)業的母機。重(zhong)型龍(long)門(men)刨(bao)銑(xian)床的工(gong)作(zuo)臺帶著(zhu)工(gong)件(jian)通過門(men)式框(kuang)架作(zuo)直線往復(fu)運(yun)動，空行(xing)程(cheng)速度(du)大于工(gong)作(zuo)行(xing)程(cheng)速度(du)。橫梁(liang)上(shang)(shang)(shang)一(yi)般裝有(you)兩個垂直刀架，刀架滑(hua)座可(ke)(ke)在垂直面內回轉(zhuan)一(yi)個角度(du)，并可(ke)(ke)沿橫梁(liang)作(zuo)橫向進給運(yun)動，刨(bao)刀可(ke)(ke)在刀架上(shang)(shang)(shang)作(zuo)垂直或斜向進給運(yun)動;橫梁(liang)可(ke)(ke)在兩立柱(zhu)上(shang)(shang)(shang)作(zuo)上(shang)(shang)(shang)下調整。

　　一般(ban)在兩個立柱上還安裝可沿立柱上下移動(dong)(dong)(dong)的(de)側刀(dao)架，以擴(kuo)大加工(gong)(gong)(gong)范(fan)圍工(gong)(gong)(gong)作(zuo)臺回程時(shi)(shi)能機動(dong)(dong)(dong)抬(tai)刀(dao)，以免劃傷工(gong)(gong)(gong)件表面。機床(chuang)(chuang)工(gong)(gong)(gong)作(zuo)臺的(de)驅動(dong)(dong)(dong)可用發電機-電動(dong)(dong)(dong)機組(zu)或用可控(kong)硅直流調速(su)(su)方式(shi)，調速(su)(su)范(fan)圍較大，在低速(su)(su)時(shi)(shi)也能獲得較大的(de)驅動(dong)(dong)(dong)力。有(you)的(de)龍(long)(long)門(men)刨(bao)床(chuang)(chuang)還附有(you)銑頭和(he)磨(mo)頭，變型為重(zhong)(zhong)型龍(long)(long)門(men)刨(bao)銑床(chuang)(chuang)和(he)龍(long)(long)門(men)刨(bao)銑磨(mo)床(chuang)(chuang)，工(gong)(gong)(gong)作(zuo)臺既可作(zuo)快(kuai)速(su)(su)的(de)主(zhu)運動(dong)(dong)(dong)，也可作(zuo)慢速(su)(su)的(de)進給運動(dong)(dong)(dong)，主(zhu)要(yao)用于重(zhong)(zhong)型工(gong)(gong)(gong)件在一次安裝中進行刨(bao)削(xue)、銑削(xue)和(he)磨(mo)削(xue)平(ping)面等加工(gong)(gong)(gong)。
