隨著機械化的(de)(de)快速(su)發展(zhan)，道(dao)生(sheng)數(shu)控車(che)床(chuang)廣為(wei)人(ren)知，那么道(dao)生(sheng)數(shu)控車(che)床(chuang)的(de)(de)正常使用需要滿足哪些(xie)條(tiao)件呢(ni)？下面跟著文章來了解一下。 環(huan)境(jing)設(she)計要求(qiu)。道(dao)生(sheng)數(shu)控車(che)床(chuang)的(de)(de)位置應(ying)遠(yuan)離振(zhen)源(yuan)、應(ying)避(bi)免(mian)學(xue)生(sheng)陽光可以(yi)(yi)直接進行照射和(he)熱輻射的(de)(de)影(ying)(ying)響(xiang)(xiang)，避(bi)免(mian)出(chu)現潮濕(shi)(shi)和(he)氣流的(de)(de)影(ying)(ying)響(xiang)(xiang)。如(ru)車(che)床(chuang)附近有振(zhen)源(yuan)，則車(che)床(chuang)四(si)周(zhou)應(ying)設(she)置防(fang)振(zhen)溝。否則將企業直接通過(guo)影(ying)(ying)響(xiang)(xiang)車(che)床(chuang)的(de)(de)加工(gong)技術精度(du)(du)(du)及(ji)穩(wen)定(ding)性，將使中國(guo)電子信息元件接觸社會(hui)不良(liang)，發生(sheng)系(xi)統(tong)(tong)故障(zhang)，影(ying)(ying)響(xiang)(xiang)車(che)床(chuang)的(de)(de)可靠性。電力需求(qiu)。 溫度(du)(du)(du)條(tiao)件。道(dao)生(sheng)數(shu)控車(che)床(chuang)的(de)(de)環(huan)境(jing)溫度(du)(du)(du)一般(ban)在(zai)攝(she)氏(shi)30度(du)(du)(du)以(yi)(yi)下，相對溫度(du)(du)(du)一般(ban)在(zai)攝(she)氏(shi)0.8度(du)(du)(du)以(yi)(yi)下，電子元件內裝有排氣風扇(shan)或冷(leng)卻風扇(shan)，以(yi)(yi)保(bao)持處理器(qi)的(de)(de)溫度(du)(du)(du)恒定(ding)或溫差很小。高(gao)溫高(gao)濕(shi)(shi)會(hui)降低控制(zhi)系(xi)統(tong)(tong)元件的(de)(de)壽(shou)命，導致(zhi)更多的(de)(de)故障(zhang)。溫度(du)(du)(du)和(he)濕(shi)(shi)度(du)(du)(du)的(de)(de)增加，灰塵在(zai)集成電路板(ban)上的(de)(de)增加會(hui)產生(sheng)粘結，并導致(zhi)短(duan)路。
