眾所周知，帶阿拉善鋸床在金屬切削領域的廣泛應用，使得高速加工技術得以迅速發展。如何充分利用好帶阿拉善鋸床的各項優越性能和維護好帶鋸床的精度，就顯得至關重要，現在就結合鋸床廠家技術人員的鋸床使用經驗，先說說帶鋸床在電源方面需要注意的一些細節和常識，希望會對大家有幫助。
電源(yuan)是維持(chi)系(xi)統(tong)正(zheng)常工作的(de)(de)能源(yuan)支持(chi)局部，失效或(huo)故(gu)障的(de)(de)直接結(jie)果(guo)是造成鋸床整個系(xi)統(tong)的(de)(de)停機或(huo)毀壞整個系(xi)統(tong)。同時(shi)，由于鋸床系(xi)統(tong)使(shi)用(yong)的(de)(de)三相交流380V電源(yuan)，所以平安(an)性也是帶鋸床設備裝置前期工作中重要的(de)(de)一(yi)環，基于以上(shang)的(de)(de)原(yuan)因(yin)，對帶鋸床設備使(shi)用(yong)的(de)(de)電源(yuan)有以下(xia)的(de)(de)要求：
一、電(dian)網(wang)電(dian)壓動搖應該控(kong)制在＋10％～15％之間，而(er)我國電(dian)源動搖較大，質量(liang)差，還隱藏有如(ru)高(gao)頻脈(mo)沖(chong)這一類的干擾(rao)，加上(shang)人(ren)為的因素（如(ru)突然拉閘斷電(dian)等）電(dian)高(gao)峰期間，例如(ru)白晝上(shang)班或下班前的一個小時左右以及晚上(shang)，往往超差較多，甚至達到±20％。使機(ji)床報警而(er)無法進行正(zheng)常工作，并對帶鋸(ju)床電(dian)源系統(tong)造成損壞(huai)。甚至導致(zhi)有關參數數據的丟失等。
建議在(zai)帶鋸床較集中(zhong)的車間配置具有自動彌補調(diao)節功能的交流穩壓供電(dian)系統。
二、建議把鋸床電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)設備(bei)連(lian)接(jie)到單一電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)上(shang)。如(ru)果需(xu)要用其他(ta)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)供電(dian)(dian)(dian)(dian)(dian)(dian)給電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)設備(bei)的(de)某些(xie)局(ju)部（如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)路、電(dian)(dian)(dian)(dian)(dian)(dian)磁離合(he)器(qi)）這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)宜(yi)盡可(ke)能(neng)(neng)取自(zi)組成為機械電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)設備(bei)一部分(fen)的(de)器(qi)件（如(ru)變壓器(qi)、換能(neng)(neng)器(qi)等）對大(da)型復雜機械包括許(xu)多以協同(tong)方式一起工作的(de)且占用較大(da)空(kong)間的(de)機械，可(ke)能(neng)(neng)需(xu)要一個(ge)以上(shang)的(de)引人電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)，這要由場地電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)配置來定。
除非機械(xie)電(dian)(dian)(dian)氣設(she)備采(cai)用插頭／插座直接連接電(dian)(dian)(dian)源處，否則建議電(dian)(dian)(dian)源線直接連到(dao)電(dian)(dian)(dian)源切斷開關的電(dian)(dian)(dian)源端子上。如果這樣做不到(dao)則應為(wei)電(dian)(dian)(dian)源線設(she)置獨立的接線座。
電源切斷開關的手柄應容易接(jie)近(jin)，應安裝在易于操作位置以上0.6M1.9M間。上限(xian)值建議(yi)為1.7M這(zhe)樣可(ke)以在發生緊急情況下迅速斷電，減少損失和人員傷亡。
三、鋸(ju)(ju)床(chuang)(chuang)(chuang)系統(tong)(tong)對于壓(ya)(ya)(ya)縮空(kong)氣供(gong)給系統(tong)(tong)的要求帶(dai)鋸(ju)(ju)床(chuang)(chuang)(chuang)一般都使用(yong)了不(bu)少氣動元件(jian)，所以廠房內(nei)應接人清(qing)潔的干(gan)燥的壓(ya)(ya)(ya)縮空(kong)氣供(gong)給系統(tong)(tong)網(wang)絡。其(qi)流量和壓(ya)(ya)(ya)力應符合要求。壓(ya)(ya)(ya)縮空(kong)氣機要裝(zhuang)置(zhi)在遠離數控機床(chuang)(chuang)(chuang)包括(kuo)帶(dai)鋸(ju)(ju)床(chuang)(chuang)(chuang)地方。根據廠房內(nei)的布置(zhi)情況、用(yong)氣量大小(xiao)，應考慮(lv)給壓(ya)(ya)(ya)縮空(kong)氣供(gong)給系統(tong)(tong)網(wang)絡裝(zhuang)置(zhi)冷凍空(kong)氣于煤機、空(kong)氣過(guo)濾器、儲氣罐(guan)、平安閥等設(she)備。
四、鋸(ju)(ju)(ju)床系統對于工作環境(jing)的要(yao)求精密數控設備一般有恒溫(wen)環境(jing)的要(yao)求，只有在恒溫(wen)條件下，才(cai)干確保(bao)帶鋸(ju)(ju)(ju)床精度和(he)加工度。一般普通(tong)型鋸(ju)(ju)(ju)床對室溫(wen)沒有具體(ti)要(yao)求，但大(da)量(liang)實踐(jian)標明，當室溫(wen)過(guo)高時鋸(ju)(ju)(ju)床系統的故障率大(da)大(da)增加。
