眾所周知，帶廊坊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。如何充分利用好帶廊坊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(dian)源是維(wei)持系(xi)統正常(chang)工(gong)作的(de)能源支持局部，失效或故障的(de)直接(jie)結果是造成鋸(ju)(ju)床(chuang)(chuang)整個(ge)系(xi)統的(de)停機或毀(hui)壞(huai)整個(ge)系(xi)統。同(tong)時，由于鋸(ju)(ju)床(chuang)(chuang)系(xi)統使(shi)用(yong)的(de)三相(xiang)交流380V電(dian)源，所以(yi)平安性也(ye)是帶鋸(ju)(ju)床(chuang)(chuang)設備(bei)裝置前期工(gong)作中(zhong)重(zhong)要的(de)一環，基于以(yi)上的(de)原(yuan)因，對帶鋸(ju)(ju)床(chuang)(chuang)設備(bei)使(shi)用(yong)的(de)電(dian)源有以(yi)下的(de)要求：
一(yi)、電(dian)(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)(dian)壓動(dong)搖應該控制(zhi)在＋10％～15％之(zhi)間(jian)，而我國電(dian)(dian)(dian)(dian)(dian)源動(dong)搖較大，質量(liang)差(cha)，還隱藏有如(ru)高頻(pin)脈(mo)沖(chong)這一(yi)類(lei)的(de)(de)干擾(rao)，加上人為的(de)(de)因素（如(ru)突然拉閘斷電(dian)(dian)(dian)(dian)(dian)等）電(dian)(dian)(dian)(dian)(dian)高峰期間(jian)，例(li)如(ru)白晝(zhou)上班(ban)或下(xia)班(ban)前的(de)(de)一(yi)個小時(shi)左右以及晚上，往(wang)往(wang)超差(cha)較多，甚(shen)至達到±20％。使(shi)機床報警而無法進行(xing)正常工作，并對帶(dai)鋸床電(dian)(dian)(dian)(dian)(dian)源系統造成損壞。甚(shen)至導致有關(guan)參數數據的(de)(de)丟失等。
建議在帶鋸床較集中的車間配置具有自動彌補(bu)調(diao)節功(gong)能的交(jiao)流(liu)穩壓供電系統。
二(er)、建議把鋸床電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)設備連接到單一(yi)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)上(shang)。如(ru)果需(xu)要(yao)用其他電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)供電(dian)(dian)(dian)(dian)(dian)給電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)設備的某些局(ju)部（如(ru)電(dian)(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)(dian)路、電(dian)(dian)(dian)(dian)(dian)磁離合器）這些電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)宜盡可能(neng)(neng)取(qu)自組(zu)成為(wei)機(ji)械(xie)電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)設備一(yi)部分(fen)的器件（如(ru)變壓器、換能(neng)(neng)器等）對大型復雜(za)機(ji)械(xie)包括許多以(yi)協同(tong)方式一(yi)起工作(zuo)的且占(zhan)用較大空(kong)間的機(ji)械(xie)，可能(neng)(neng)需(xu)要(yao)一(yi)個以(yi)上(shang)的引人(ren)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)，這要(yao)由場地電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)的配(pei)置來定。
除非(fei)機(ji)械(xie)電(dian)氣設(she)備采用插頭(tou)／插座直接連接電(dian)源(yuan)處(chu)，否則(ze)建議電(dian)源(yuan)線直接連到(dao)(dao)電(dian)源(yuan)切斷開(kai)關的電(dian)源(yuan)端子上。如果這樣做不到(dao)(dao)則(ze)應(ying)為電(dian)源(yuan)線設(she)置獨立(li)的接線座。
電源切斷開關的(de)手柄(bing)應容易(yi)接近，應安裝在易(yi)于操作(zuo)位(wei)置(zhi)以(yi)(yi)上(shang)0.6M1.9M間(jian)。上(shang)限(xian)值建(jian)議為1.7M這樣可以(yi)(yi)在發(fa)生緊急情況下迅速(su)斷電，減少損失和人員傷亡。
三、鋸床(chuang)系(xi)統(tong)對于壓縮空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)供(gong)給系(xi)統(tong)的(de)(de)要(yao)求帶鋸床(chuang)一般都使用了不少氣(qi)(qi)(qi)動元件，所以(yi)廠(chang)房內應接人清潔的(de)(de)干燥(zao)的(de)(de)壓縮空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)供(gong)給系(xi)統(tong)網(wang)絡。其(qi)流量和壓力應符合要(yao)求。壓縮空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)機要(yao)裝置在遠離數控機床(chuang)包括(kuo)帶鋸床(chuang)地方。根據廠(chang)房內的(de)(de)布置情況、用氣(qi)(qi)(qi)量大小(xiao)，應考慮給壓縮空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)供(gong)給系(xi)統(tong)網(wang)絡裝置冷凍空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)于煤機、空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)過濾器、儲氣(qi)(qi)(qi)罐、平安(an)閥等設備。
四、鋸床(chuang)系統(tong)對于工(gong)作環境的(de)要求精密數(shu)控(kong)設備一般有恒溫(wen)環境的(de)要求，只(zhi)有在恒溫(wen)條件下，才(cai)干確保帶鋸床(chuang)精度和加工(gong)度。一般普通型鋸床(chuang)對室溫(wen)沒有具體要求，但大量實踐標明，當室溫(wen)過高時鋸床(chuang)系統(tong)的(de)故障率大大增(zeng)加。
