Paving the path for China to become a strong country in cutting tools
Date:
28/12/2011
Chinamac Journal (CMJ) - Dec 2011 Issue
近10年來,中國刀具行業持續高速增長。在快速發展的背後,我們也應該清醒地認識到,國內工具行業的高增長率中,有相當一部分企業以犧牲環境為代價,以廉價勞動力為基礎,生產劣質產品獲取暴利。麻花鑽、錐柄鑽、絲錐、鋸片銑刀等低端市場一片混戰,而高端產品增長緩慢,汽車、模具、航空航天等行業的高、精、尖的複雜刀具大部分依賴進口。目前,中國的金屬切削刀具已經開始從高速鋼刀具轉向硬質合金刀具的開發生產,但力度還不夠,仍以低檔居多。因此,要把高端產品過渡作為一個非常重要的任務來抓,尤其是美國經濟增長放緩,歐洲市場疲軟,低檔工具出口受阻,從能源和原材料角度看,大量出口低檔工具已不合時宜,政府也不會給力。中國機床工具工業協會統計數據表明:中國消耗了全世界40%的工具材料,銷售收入卻只佔全世界工具的12%∼15%,這顯然不符合國家提出的資源節約型的科學發展觀。針對嚴峻的形勢,國內工具行業應審時度勢...

發那科焊接智能機器人柔性加工汽車零部件零部件焊接需要柔性化製造技術汽車生產的四大工藝以及汽車關鍵零部件的生產,由於生產環境的危險性和工序的複雜性,決定了由工業機器人的參與可大大提高生產安全和工作效率。例如在汽車車身生產中,有大量衝壓、焊接、檢測等工序,目前都是由工業機器人參與完成。特別是焊接方面,一條焊接線就要有大量的工業機器人參與。目前中國生產的桑塔納、大眾、別克、賽歐等後橋、副車架、搖臂、懸架、減振器等轎車底盤零件大都是以MIG焊接工藝為主的受力安全零件,主要構件採用衝壓焊接,板厚平均為1.5~4mm,焊接主要以搭接、角接接頭形式為主,焊接質量要求相當高,其質量的好壞直接影響到轎車的安全性能,因此要求焊接機器人系統必須高度柔性化。即適應於不同零件的焊接夾具;能短時間內快速調換氣、電信號、配管、配線快速改換;控制程序必須能預置和快速轉換,最大程度地發揮機器人特點以使一套機器人系統能...

High-efficiency and high-speed CNC machine tools for titanium alloy machining

Chinamac Journal (CMJ) - Dec 2011 Issue
現今,鋁合金材高效高速數控加工機床技術已相當成熟,並得到了廣泛應用。隨著鈦合金材整體構件在大型飛機上的應用增多,其切削加工的低效已成為大型飛機快速製造的瓶頸,配置有高功率高轉矩主軸的鈦合金材高速數控MC機床已成為許多航宇製造業用戶特別關注和優先考慮的現代化先進關鍵製造裝備之一。所有這些,促使工業界更加關注鈦合金材HEM-HSM加工技術及其裝備的發展與工業應用。世界許多著名數控機床和主軸製造商也都加強了對該技術領域的開發研究力度,一些機床製造商甚至還成立專門的研發中心,積極為航宇製造業推出了多種類型用於大型複雜鈦合金材整體結構件HEM-HSM加工應用的數控加工機床。眾所周知,直到目前為止工業界對高速加工技術HSM還未有一種統一、明確、權威和公認的定義。實際上,HSM 技術中“高速”是為一種相對性概念,對不同工件材料或不同切削工藝類型其HSM定義的“高速”速度範圍則是不同的。鈦合金材相對...

縱觀中國經濟,2010年超過了10%的增長速度,從而取代日本成為世界第二大經濟體,而且每年持續保持平均10.5%的增長率。在這期間,中國的汽車銷量在2009年達到了1,350萬輛從而超過美國,2010年達到1,800萬輛,其差距進一步拉大,成為世界上最大的汽車市場。在大環境的促進下,中國機床行業也走上了發展的快車道。中國機床的消費量在2000年佔到全球機床消費量的10%,到2010年已經高達46%,居全球首位。並且在機床生產方面,也於2009年超過日本、德國,成為機床生產第一大國。可以說,中國已經確立了作為製造大國不可動搖的地位。某大型外資機床公司的總經理在一次會議上表示,機床消費的水平代表著製造業的發展水平。這足以說明,中國製造已經成為全球製造的重要力量。中國製造的核心,尤其以中高端數控機床為切入從單品種大批量生產向多品種訂單式生產過渡,這也正成為一種趨勢。市場的個性化與多樣化帶來...

Chinamac Journal (CMJ) - Oct 2011 Issue
近年來,機床技術的發展突飛猛進——數控機床的精度和速度大約8年就提高一倍。機床製造技術的發展和市場對機床的性能要求不斷提高。機床的結構也變得越來越簡單,機床的精度、速度和產品的可靠性要求也越來越高。與此同時,機床行業的節能、環保、綠色製造等理念也愈加深入人心。這些未來趨勢將運動控制產品的品質水準要求提高到了新的高度。機床行業使用的運動控制產品非常廣泛,單片機、PLC、定位模塊、數控系統、伺服系統等都有涉及,更有廠家自主研發了電氣設備。在一些高端應用領域,如高精度的磨床、旋轉刀庫、伺服衝壓送料機、自動化專機流水線等,對於控制和工藝都有特殊的需求,這些都不是普通的脈衝發生產品或者定位產品可以簡單應對的。運動控制產品的製造商們,正在加大研發,為機床行業提供傳動於控制系統的解決方案。博世力士樂:IndraMotion MTX micro系統早在2009年,博世力士樂公司基於緊湊、簡單和高效的...

在新能源的發展過程中,風能作為一種清潔的可再生能源,越來越受到世界各國的重視。歐洲各國、美國、中國等都在本國的能源規劃中給予大力的支持和推進。世界風能協會(WWEA)主席Dr. Anil Knae曾表示,“風電,是世界能源體系改革的機車頭。”風能的利用一直是人類的夢想,作為一項環保、綠色、可再生的能源產業,在當今世界傳統能源面臨枯竭、環境問題日益嚴峻的大背景下,受到了極大的重視。風電產業的快速發展,促使風電機組部件加工所需的精密、高效的數控機床和高端刀具的需求也大量增長。風電,為機床工具產業的進一步發展提供了“新的能源”。對機床工具要求嚴苛風電設備對於機床工具及工藝來講,可以稱得上“苛刻”。風電設備變速箱體屬於大型箱體,結構複雜,各種部件的製造需要不同機床設備進行加工。兆瓦級風電設備變速箱根據發電量的不同,直徑在2-3米不等,大部分為分體結構,加工時需要用到鏜桿直徑約16-250毫米...
