機械畢業(yè)論文文獻(xiàn)翻譯數(shù)控機床在國內(nèi)發(fā)展?fàn)顩r概括--機械相關(guān)文獻(xiàn)翻譯

1、<p>　　國內(nèi)數(shù)控機床發(fā)展概括</p><p>　　數(shù)控機床是由美國發(fā)明家約翰·帕森斯上個世紀(jì)發(fā)明的。隨著電子信息技術(shù)的發(fā)展，世界機床業(yè)已進(jìn)入了以數(shù)字化制造技術(shù)為核心的機電一體化時代，其中數(shù)控機床就是代表產(chǎn)品之一。數(shù)控機床是制造業(yè)的加工母機和國民經(jīng)濟的重要基礎(chǔ)。它為國民經(jīng)濟各個部門提供裝備和手段，具有無限放大的經(jīng)濟與社會效應(yīng)。歐、美、日等工業(yè)化國家已先后完成了數(shù)控機床產(chǎn)業(yè)化進(jìn)程，而中國從20

2、世紀(jì)80年代開始起步，仍處于發(fā)展階段。</p><p>　　作為現(xiàn)代工業(yè)基石的機床產(chǎn)業(yè)，是工業(yè)經(jīng)濟發(fā)展過程中無論如何都不能繞過一個關(guān)鍵性問題，中國機床產(chǎn)業(yè)由于先天不足，一直在中高端機床項目發(fā)展上落于國外主流水準(zhǔn)，正處于一個追趕的過程當(dāng)中。</p><p>　　中國數(shù)控機床仍然較為落后。中國數(shù)控機床市場巨大，與國外產(chǎn)品相比，中國的差距主要是機床的高速高效化和精密化上，中國正處于工業(yè)化中期，即

3、從解決短缺為主的開放逐步向建設(shè)經(jīng)濟強國轉(zhuǎn)變，從脫貧向致富轉(zhuǎn)變，煤炭、汽車、鋼鐵、房地產(chǎn)、建材、機械、電子、化工等一批以重工業(yè)為基礎(chǔ)的高增長行業(yè)發(fā)展勢頭強勁，構(gòu)成了對機床市場尤其是數(shù)控機床的巨大需求。</p><p>　　中國機床行業(yè)加速轉(zhuǎn)型面臨四大制約因素。中國的數(shù)控機床技術(shù)現(xiàn)在目前最多只能做到五軸聯(lián)動，并且據(jù)有關(guān)人士說這個五軸還是作秀成份居多，五軸以上幾乎就是全部進(jìn)口，并且在多點聯(lián)動的技術(shù)上也和國外技術(shù)水準(zhǔn)存在

4、非常大的差距。</p><p>　　國內(nèi)市場國際化競爭加?。河捎谥械蜋n數(shù)控機床市場萎縮和生產(chǎn)能力過剩，加之國外產(chǎn)品低價涌入，市場競爭將進(jìn)一步加劇。而高檔產(chǎn)品由于長期以來一直依賴進(jìn)口，國內(nèi)產(chǎn)品更加面臨著國際化競爭的嚴(yán)峻挑戰(zhàn)。</p><p>　　以技術(shù)領(lǐng)先的策略正在向以客戶為中心的策略轉(zhuǎn)變：經(jīng)濟危機往往會催生大規(guī)模的產(chǎn)業(yè)升級和企業(yè)轉(zhuǎn)型，機床工具行業(yè)實現(xiàn)制造業(yè)服務(wù)化，核心在于要以客戶為中心，積

5、極提供客戶需要的個性化服務(wù)。因此，從簡單的賣產(chǎn)品轉(zhuǎn)向提供整體解決方案、從以技術(shù)為中心向以客戶為中心轉(zhuǎn)變成為當(dāng)今的趨勢。</p><p>　　中國的產(chǎn)品與中國市場需求反差較大，產(chǎn)品結(jié)構(gòu)亟待快速調(diào)整：中國機床行業(yè)雖然保持多年持續(xù)快速發(fā)展，但是產(chǎn)業(yè)和產(chǎn)品結(jié)構(gòu)不合理的現(xiàn)象依然存在，整個行業(yè)大而不強，高檔產(chǎn)品還大量依賴進(jìn)口。國產(chǎn)機床的國內(nèi)市場占有率雖然已經(jīng)有一定的提高，但是高檔數(shù)控機床、核心功能部件在國內(nèi)市場占有率還很低，

6、全行業(yè)替代進(jìn)口的潛力非常巨大。</p><p>　　企業(yè)技術(shù)創(chuàng)新模式有待完善：由于中國機床企業(yè)的地位、工業(yè)化水平和品牌影響力在逐步提升，要成為工業(yè)強國，其技術(shù)的獲得再也不能依賴別人。過去，中國走了一條從模仿到引進(jìn)的道路，從現(xiàn)在開始必須走自主創(chuàng)新的道路。企業(yè)技術(shù)遇到新的封鎖，建立自主、新型、戰(zhàn)略性的產(chǎn)學(xué)研創(chuàng)新模式是支撐產(chǎn)品結(jié)構(gòu)調(diào)整技術(shù)來源的惟一途徑。</p><p>　　中國數(shù)控機床行業(yè)將延

7、續(xù)結(jié)構(gòu)調(diào)整的勢頭，不斷以新產(chǎn)品、新亮點占領(lǐng)更大市場。數(shù)控切割機床按切割方式可分為火焰切割和等離子切割兩大類。隨著下游行業(yè)需求的不斷提高，對數(shù)控機床配件提出了更大的需求和更高的要求。</p><p>　　東北地區(qū)發(fā)展不快，其他地方的發(fā)展也比較緩慢。三是調(diào)結(jié)構(gòu)促轉(zhuǎn)型取得成效。專家認(rèn)為面對金融危機，廣大企業(yè)應(yīng)不斷調(diào)整結(jié)構(gòu)、提高質(zhì)量、增加品種及推動產(chǎn)業(yè)升級，再加上企業(yè)加強管理，降低費用，所以企業(yè)效益明顯好轉(zhuǎn)。數(shù)控切割機床

8、裝飾性發(fā)展趨勢可見一斑，數(shù)控切割機床更多的是強調(diào)在機械性能、操作簡便、價格經(jīng)濟、加工精度穩(wěn)定等方面。在金屬材料加工日益要求普及和批量化的今天，數(shù)控切割機床除了要滿足上述功能性外，還要具有多切割方式的適用性。</p><p>　　國內(nèi)數(shù)控機床企業(yè)為了提高自身實力，更快地拓展國際市場，將采取多種手段加快和國外企業(yè)的融合以提高產(chǎn)品質(zhì)量、提高競爭力。在繼續(xù)開拓美國、日本等國家市場的同時，在東南亞、中東、俄羅斯、歐洲、非洲

9、等也全面開花。據(jù)了解，當(dāng)前金屬切割數(shù)控機床行業(yè)運行具有以下幾個特點：一是外銷企業(yè)困難較大。從規(guī)模以上企業(yè)來看，以內(nèi)銷為主的品牌企業(yè)發(fā)展勢頭較好。沒有品牌的中小企業(yè)發(fā)展比較困難。二是各地區(qū)發(fā)展不夠均衡，浙江、山東、河北、北京以及四川發(fā)展比較快，廣東的民營企業(yè)發(fā)展也較快。</p><p>　　數(shù)控切割機床行業(yè)多數(shù)企業(yè)都是依靠降低產(chǎn)品售價來獲得市場，造成的后果是產(chǎn)品價格低、附加值低、利潤低，企業(yè)沒有足夠的資金持續(xù)發(fā)展。

10、隨著產(chǎn)業(yè)的發(fā)展和競爭的升級，提高產(chǎn)品技術(shù)含量，擁有自主的專利、設(shè)計，注重品牌的打造和營銷才是企業(yè)長期發(fā)展的最佳選擇。</p><p>　　中國機床行業(yè)在過去幾年實現(xiàn)了持續(xù)超高速的發(fā)展，一直到2011年上半年，需求仍很旺盛，但是從下半年開始，需求增勢明顯趨緩，新增訂單劇烈下滑，經(jīng)濟效益狀況逐漸趨于嚴(yán)峻，利潤率持續(xù)下降。</p><p>　　在“十二五”期間，國家實施積極的財政政策和穩(wěn)健的貨幣

11、政策，隨著科技進(jìn)步、產(chǎn)品升級以及國家重點工程、地方投資項目的不斷推進(jìn)，國民經(jīng)濟各行業(yè)對機床工具產(chǎn)品的需求水平將進(jìn)一步提高，國防現(xiàn)代化對高水平機床的需求將更為迫切，市場需求將向更高層次發(fā)展，新一輪的市場競爭也將更加激烈。</p><p>　　由于行業(yè)景氣度低迷，下游制造型企業(yè)對機床需求下降，所以我國機床行業(yè)一直處于低迷狀態(tài)，升級轉(zhuǎn)型成為行業(yè)近幾年的關(guān)鍵詞，經(jīng)濟型數(shù)控機床則成為振興裝備制造業(yè)的重點之一。</p&

12、gt;<p>　　我國的鑄造機床產(chǎn)業(yè)取得了一定的成績，但是其發(fā)展仍然面臨著許多制約性問題，技術(shù)創(chuàng)新一直是國內(nèi)鑄造機床行業(yè)的硬傷。與國外的鑄造機床產(chǎn)業(yè)相比，我國的鑄造機床產(chǎn)業(yè)在制造工藝水平上明顯落后，這使得其在核心運行部件的技術(shù)水平和運行速度、產(chǎn)品精度保持性以及機床的可靠性上有著明顯的不足。</p><p>　　我國鑄造機床企業(yè)缺乏自主創(chuàng)新和基礎(chǔ)理論研究的意識與能力，這就制約了我國鑄造機床技術(shù)的發(fā)展，

13、要改變這種現(xiàn)狀，就要深入研究用戶行業(yè)產(chǎn)品工藝的特點和要求，結(jié)合工藝特點開發(fā)出高水平加工設(shè)備，同時，還要注重基礎(chǔ)理論工作的研究，這樣才能讓我國鑄造機床產(chǎn)業(yè)在不久的將來有更好的發(fā)展。國家出臺的一系列政策，大力建設(shè)新興企業(yè)，高新技術(shù)企業(yè)，抓住了這一時機，企業(yè)內(nèi)部出臺了“調(diào)整與振興”、“自主創(chuàng)新”等一系列政策，升級企業(yè)機床技術(shù)，嚴(yán)格保證產(chǎn)品質(zhì)量，為加快鑄造機床行業(yè)的發(fā)展提供了良好的環(huán)境跟市場。</p><p>　　機床工

14、具行業(yè)作為國家基礎(chǔ)性和戰(zhàn)略性產(chǎn)業(yè)，在“十二五”規(guī)劃中，已明確將自主創(chuàng)新戰(zhàn)略作為最主要的一個組成部分，著重強調(diào)了要以技術(shù)創(chuàng)新工程來支撐和引領(lǐng)行業(yè)發(fā)展。我國機床工具行業(yè)的發(fā)展必須立足于自主創(chuàng)新，通過自主研發(fā)原始創(chuàng)新、引進(jìn)技術(shù)消化吸收再創(chuàng)新、集成現(xiàn)有技術(shù)創(chuàng)新等方式，實現(xiàn)關(guān)鍵技術(shù)突破和產(chǎn)業(yè)升級。構(gòu)建和完善以企業(yè)為主體、以市場為導(dǎo)向、產(chǎn)學(xué)研用相結(jié)合的技術(shù)創(chuàng)新體系;堅持加大研發(fā)費用投入;加強關(guān)鍵技術(shù)、共性技術(shù)的研究，力爭在基礎(chǔ)和共性技術(shù)攻關(guān)上有所突

15、破，提高產(chǎn)品開發(fā)技術(shù)水平。</p><p><b>　　技術(shù)發(fā)展</b></p><p>　　高速、精密、復(fù)合、智能和綠色是數(shù)控機床技術(shù)發(fā)展的總趨勢，近幾年來，在實用化和產(chǎn)業(yè)化等方面取得可喜成績。主要表現(xiàn)在：</p><p>　　1、機床復(fù)合技術(shù)進(jìn)一步擴展隨著數(shù)控機床技術(shù)進(jìn)步，復(fù)合加工技術(shù)日趨成熟，包括銑-車復(fù)合、車銑復(fù)合、車-鏜-鉆-齒輪加工

16、等復(fù)合，車磨復(fù)合，成形復(fù)合加工、特種復(fù)合加工等，復(fù)合加工的精度和效率大大提高?！耙慌_機床就是一個加工廠”、“一次裝卡，完全加工”等理念正在被更多人接受，復(fù)合加工機床發(fā)展正呈現(xiàn)多樣化的態(tài)勢。</p><p>　　2、數(shù)控機床的智能化技術(shù)有新的突破，在數(shù)控系統(tǒng)的性能上得到了較多體現(xiàn)。如：自動調(diào)整干涉防碰撞功能、斷電后工件自動退出安全區(qū)斷電保護(hù)功能、加工零件檢測和自動補償學(xué)習(xí)功能、高精度加工零件智能化參數(shù)選用功能、加工

20、t;　　發(fā)展問題</b></p><p>　　國內(nèi)數(shù)控機床的需求日益增長，數(shù)控機床的發(fā)展推動了數(shù)控機床功能部件的創(chuàng)新升級。目前我國高檔數(shù)控機床關(guān)鍵功能部件工業(yè)還不能滿足國內(nèi)需要，國內(nèi)數(shù)控功能部件產(chǎn)業(yè)主要存在以下問題。</p><p>　　1、適應(yīng)性和滿足度遠(yuǎn)達(dá)不到市場需求</p><p>　　從當(dāng)前我國數(shù)控機床的發(fā)展趨勢來看，國產(chǎn)功能部件的適應(yīng)性和滿足度

21、遠(yuǎn)遠(yuǎn)達(dá)不到市場的需求。主要表現(xiàn)在：</p><p>　　1）我國功能部件的產(chǎn)品水平和國外有一定差距。我國生產(chǎn)的功能部件多數(shù)以勞動密集型為主，技術(shù)含量低，難以適應(yīng)國產(chǎn)數(shù)控機床的發(fā)展速度和技術(shù)要求，特別是高檔數(shù)控機床。</p><p>　　2）我國功能部件開發(fā)能力較弱，新產(chǎn)品開發(fā)速度慢，多數(shù)功能部件需要與國外合作開發(fā)、合作生產(chǎn)、合資經(jīng)營，甚至只能組裝。雖然這兩年形勢有顯著變化，但高技術(shù)、最新型

22、的功能部件，我國尚在研制過程中，市場占有率前景依然不容樂觀。</p><p>　　2、我國數(shù)控功能部件生產(chǎn)企業(yè)的規(guī)模小</p><p>　　據(jù)統(tǒng)計我國固定資產(chǎn)達(dá)到1000萬元以上的功能部件生產(chǎn)企業(yè)有70多家，占全部生產(chǎn)企業(yè)的10%以下。我國的功能部件生產(chǎn)企業(yè)的“出身”有4種：一是從研究院所、大專院校以技術(shù)支撐發(fā)展而來的企業(yè)，可稱為“院所型”。這些企業(yè)的特點是：有一定技術(shù)基礎(chǔ)和人才基礎(chǔ)，有多

23、項技術(shù)的發(fā)展?jié)摿?，但生產(chǎn)手段較弱，難以在短時間內(nèi)形成產(chǎn)業(yè)規(guī)模，在成本、營銷、服務(wù)等方面也存在一些差距；二是從主機廠逐步“獨立”、“分離”出來的以生產(chǎn)某種功能部件為主發(fā)展起來的企業(yè)，可稱之為“主廠型”。這些企業(yè)在生產(chǎn)能力、工藝水平和使用經(jīng)驗上都可以適應(yīng)市場需求，在一定程度上可以形成規(guī)模，但由于其與原主機廠有著千絲萬縷的聯(lián)系，在競爭中往往讓用戶產(chǎn)生疑慮，影響其市場開拓，同時，其開發(fā)能力也有一定的局限性，所以難以形成著名品牌；三是在江浙一帶大

24、量涌現(xiàn)出的民營企業(yè)，可稱之為“民企型”。這些企業(yè)主要以勞動密集型、單一品種為主，如護(hù)鏈罩、拖板、噴油管、排屑器、照明設(shè)備等。由于競爭激烈，其質(zhì)量和價格都能滿足中低檔數(shù)控機床的市場需要。雖然這些品種的高檔產(chǎn)品尚不能制造，還需依賴進(jìn)口，但在很大程度上，適應(yīng)了我國數(shù)控機床發(fā)展的總體需求；還有一部分外商合資企業(yè)或獨</p><p>　　3、核心零部件大量依靠進(jìn)口</p><p>　　中國數(shù)控機床行

25、業(yè)的發(fā)展令人矚目，2008年中國數(shù)控機床工具工業(yè)完成工業(yè)總產(chǎn)值34723億元，產(chǎn)品銷售產(chǎn)值3348.3億元，同比分別增長27.5%和26.0%。2002~2008年中國是世界機床第一消費國和第一進(jìn)口國。但行業(yè)迅速發(fā)展的背后，一個不能忽視的事實是，我國關(guān)鍵零部件生產(chǎn)依然受制于人，出現(xiàn)了利潤不高、產(chǎn)品缺乏核心競爭力的局面。</p><p>　　4、缺乏高技術(shù)含量威脅產(chǎn)業(yè)安全</p><p>　

26、　我國機床出口連年保持增長的喜人態(tài)勢，不過“量增價減”的尷尬直接反映出我們的技術(shù)水平。大量核心技術(shù)的缺乏和關(guān)鍵零部件的依賴直接影響到我國的機床產(chǎn)業(yè)安全。因此，我們需要強化預(yù)警工作意識，凝聚行業(yè)智慧和力量，維護(hù)產(chǎn)業(yè)安全。</p><p>　　Domestic CNC machine tools development</p><p>　　Nc machine tools is by Amer
