日前，由齊重數控裝備股份有限公司牽頭承擔的“數控立柱移動立式銑車床”課題，在重慶水輪機廠有限責任公司通過國家技術驗收。作為國家重大專項確定的十大標志性產品之一，國家重大工程項目建設急需、替代進口的高端產品25米數控雙柱移動立式銑車床的研制成功，不但突破了世界機床領域的制造極限，為我國機床領域再添國之重器，也標志著齊重數控經過幾年的艱辛努力產品技術水平成功躋身世界第一方陣，令世界刮目相看。
Recently, the "numerical control column mobile vertical milling lathe" led by Qi Heavy CNC Equipment Co., Ltd. passed the national technical check at Chongqing Hydraulic Turbine Works Co., Ltd. As one of the top ten landmark products identified by the state major projects, the construction of the country s major projects urgently needed to replace the imported high-end products 25 m CNC two-post mobile vertical milling lathe was successfully developed, not only broke the manufacturing world in the field of machine tools, It is also a milestone for our country in the field of machine tools. It also marks the success of Qixiang CNC in the world s first phalanx after years of arduous efforts in product technology.
25米數控雙柱移動立式銑車床的各項技術參數、可靠性和精度穩(wěn)定性等技術指標均達到國際先進水平，是對極限尺度下制造裝備的設計、分析、制造、檢測、控制和工藝等關鍵技術開展系統(tǒng)研究的成果體現。該臺產品最大加工直徑25米；最大加工高度6米；最大工件重量550噸；工作臺直徑10米；工作臺端、徑向跳動0.02毫米，其主要技術參數均突破了我國現有的制造能力，屬國內首創(chuàng)，可實現大件加工一次裝夾完成車、銑、鏜、鉆、攻絲、磨削全部加工工序。
Technical parameters, reliability and accuracy and stability of 25-meter CNC double-column mobile vertical milling lathe all reach the international advanced level, and are the design, analysis, manufacture, testing, control and technology of manufacturing equipment on the limit scale And other key technologies to carry out systematic research results. The maximum processing diameter of this product is 25 meters; the maximum processing height is 6 meters; the maximum work piece weight is 550 tons; the working table diameter is 10 meters; the worktable end is radial runout 0.02 mm. Its main technical parameters all break through the existing manufacturing capacity of our country, Is a domestic initiative, can achieve large-scale processing A complete car, milling, boring, drilling, tapping, grinding all processing operations.
該臺產品攻克了多項世界性關鍵技術難點，研制了整體內圈與左右兩瓣花盤帶上下楔鐵高剛度把合結構，實現了工作臺端徑跳達到0.02毫米的高精度；解決了900噸重20米跨距龍門架進給同步的難題，實現了龍門架高精度同步控制；解決了車銑復合刀架既能高轉速又能實現大扭矩的銑、鏜、鉆加工的難題，同時利用拉刀主軸和四個角油缸技術，增加連接剛度，解決了既可抓取工具柄又可抓取附件頭的難題。
The product overcomes many of the world s key technical difficulties, the development of the overall inner ring and the left and right two petals wedge with a high rigidity around the structure, to achieve the end of the table diameter jump to 0.02 mm high precision; to solve the 900 tons The problem of synchronous feeding of gantry with 20 m span is solved and high precision synchronous control of the gantry is realized. The problems of milling, boring and drilling with high speed and high torque are solved. Meanwhile, Broach spindle and four corner cylinder technology to increase the connection stiffness, which solves the problem of grabbing the tool handle and grabbing the attachment head.
