機(jī)床導(dǎo)軌在水平面內(nèi)的直線度和在垂直面內(nèi)的直線度以及鑒定前后和左右導(dǎo)軌是否扭曲（即平行度）等，都是對(duì)工件加工造成影響的主要因素。例如，導(dǎo)軌在垂直平面內(nèi)的直線度誤差，對(duì)于臥式車床，會(huì)使刀在縱向進(jìn)給過程中刀尖高低發(fā)生變化，加工的表面將產(chǎn)生圓柱度誤差（但由于刀尖的這種運(yùn)動(dòng)軌跡的誤差是發(fā)生在加工面的切向，產(chǎn)生的工件形狀誤差很?。?。對(duì)于平面磨床、銑床等進(jìn)行平面加工時(shí)，直接使加工表面造成平面度誤差。導(dǎo)軌在水平面內(nèi)的直線度誤差，對(duì)于臥式車床、外圓磨床，可使砂輪在縱向進(jìn)給過程中產(chǎn)生徑向擺動(dòng)，直接使加工表面的直徑沿全長(zhǎng)變化，造成圓柱度誤差。若是在立式銑床上加工鍵槽，將使鍵槽產(chǎn)生相對(duì)于軸線的平行度誤差。前后導(dǎo)軌平行度誤差，如前導(dǎo)軌下沉，會(huì)使刀架產(chǎn)生擺動(dòng)，刀尖的成形運(yùn)動(dòng)軌跡變成一條空間曲線，將產(chǎn)生圓柱度誤差。成都機(jī)床產(chǎn)品零件是整個(gè)機(jī)床的支撐，其精度保持性要求很高。</p><div

style="text-indent:25px">零件在磨削過程中表面發(fā)熱，隨后進(jìn)行快速冷卻（激冷）是造成表面開裂的主要原因，通常是砂輪長(zhǎng)久磨削后零件表面被砂粒和金屬屑堵塞，表面產(chǎn)生嚴(yán)重的發(fā)熱，表面的瞬間溫度在850℃以上，達(dá)到淬火加熱溫度，激冷后產(chǎn)生表面淬火，造成淬火開裂。磨削熱是砂輪與零件接觸下產(chǎn)生的，它同砂輪的種類、粒度、零件的材質(zhì)等有直接的關(guān)系，零件硬度提高，則硬質(zhì)碳化物的數(shù)量增多，造成熱導(dǎo)率降低，因此磨削熱量使零件的表面溫度升高，例如高碳鋼或含有鉻、鉬等合金鋼，在磨削過程中如參數(shù)不當(dāng)則很容易造成磨削裂紋的產(chǎn)生。</p><p style="text-indent:25px">數(shù)控機(jī)床的檢修方法有哪些？下面分享幾種兩種方法：1、替換（交換）檢修法，替換（交換）檢修法是利用各種備用電路板、模塊及其他電子元器件替換有疑點(diǎn)的電路板、模塊及其他電子元器件，從而確定故障范圍，直至查出故障點(diǎn)；在沒有備用電路板或備件時(shí)，也可采用數(shù)控機(jī)床上相同或相容的電路板、模塊及其他電子元器件來替換有疑點(diǎn)的部位，可收到同樣的效果。確定故障點(diǎn)后，再具體排除。2、參數(shù)檢修法，參數(shù)檢修法是利用數(shù)控機(jī)床生產(chǎn)廠家所提供的參數(shù)，通過核對(duì)、修正發(fā)生故障的數(shù)控機(jī)床參數(shù)，即可排除其故障，這種檢修法與其他的檢修法所不同的是它不需對(duì)硬件做任何變動(dòng)，省時(shí)省力，快捷方便。磨削裂紋檢驗(yàn)方法。無損檢測(cè)方法有超聲波探傷法，磁力探傷法，滲透探傷法。</p><div

style="text-indent:25px">機(jī)床機(jī)床大體分為兩類，以車床的工件旋轉(zhuǎn)和以鉆床、銑床、磨床為表示的或磨具旋轉(zhuǎn)進(jìn)行加工。機(jī)床以前是采用帶輪、齒輪等變換進(jìn)行機(jī)械式調(diào)速，這在操作上有問題。為了大幅度簡(jiǎn)化機(jī)械式變速機(jī)構(gòu)，多采用直流電動(dòng)機(jī)調(diào)速傳動(dòng)。要解決直流電動(dòng)機(jī)電刷維修問題，各種機(jī)床正在采用變頻器實(shí)現(xiàn)交流化。其中磨床平面磨床很早便采用變頻器了，其調(diào)速范圍較窄，加減速特性和速度精度采用通用變頻器都能充分滿足。另外，對(duì)于更新的高級(jí)磨床，電動(dòng)機(jī)轉(zhuǎn)矩脈動(dòng)的降低是一個(gè)課題，但提高通用變頻器的特性還是可以應(yīng)用的。在經(jīng)濟(jì)進(jìn)入新常態(tài)下，機(jī)床行業(yè)面臨著深刻的變革，智能化、精細(xì)化越來越成為機(jī)床行業(yè)發(fā)展趨勢(shì)。遼寧高速精密機(jī)床</p><p

style="text-indent:25px">數(shù)控機(jī)床加工工件不穩(wěn)定原因之一是工件尺度與實(shí)際尺度相差幾毫米，或某一軸向有很大改動(dòng)。毛病原因：快速定位的速度太快，驅(qū)動(dòng)和電機(jī)反響不過來；在長(zhǎng)時(shí)刻問題損耗后機(jī)械的拖板絲桿和軸承過緊卡死；刀架換刀后太松，鎖不緊；修正的程序過錯(cuò)，頭、尾沒有照應(yīng)或沒撤銷刀補(bǔ)就完畢了；體系的電子齒輪比或步距角設(shè)置過錯(cuò)。解決方案：快速定位速度太快，則恰當(dāng)調(diào)整GO的速度，切削加減速度和時(shí)刻使驅(qū)動(dòng)器和電機(jī)在額外的運(yùn)轉(zhuǎn)頻率下正常作業(yè)；在呈現(xiàn)機(jī)床磨損后發(fā)生拖板、絲桿鶴軸承過緊卡死，則有必要重新調(diào)整修正；刀架換刀后太松則查看刀架反轉(zhuǎn)時(shí)刻是否滿意，查看刀架內(nèi)部的渦輪蝸桿是否磨損，空隙是否太大，裝置是否過松等；如果是程序原因形成的，則有必要修正程序，按照工件圖紙要求改進(jìn)，挑選合理的加工工藝，按照說明書的指令要求編寫正確的程序；若發(fā)現(xiàn)尺度誤差太大則查看體系參數(shù)是否設(shè)置合理，特別是電子齒輪和步距角等參數(shù)是否被損壞，呈現(xiàn)此現(xiàn)象可經(jīng)過打百分表來丈量。遼寧高速精密機(jī)床</p></p><br
