日前，由齐重数控装备股份有限公司牵头承担的“数控立柱移动立式铣车床”课题，在重庆水轮机厂有限责任公司通过国家技术验收。作为国家重大专项确定的十大标志性产品之一，国家重大工程项目建设急需、替代进口的高端产品25米数控双柱移动立式铣车床的研制成功，不但突破了世界机床领域的制造极限，为我国机床领域再添国之重器，也标志着齐重数控经过几年的艰辛努力产品技术水平成功跻身世界第一方阵，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米数控双柱移动立式铣车床的各项技术参数、可靠性和精度稳定性等技术指标均达到国际先进水平，是对极限尺度下制造装备的设计、分析、制造、检测、控制和工艺等关键技术开展系统研究的成果体现。该台产品最大加工直径25米；最大加工高度6米；最大工件重量550吨；工作台直径10米；工作台端、径向跳动0.02毫米，其主要技术参数均突破了我国现有的制造能力，属国内首创，可实现大件加工一次装夹完成车、铣、镗、钻、攻丝、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.
  该台产品攻克了多项世界性关键技术难点，研制了整体内圈与左右两瓣花盘带上下楔铁高刚度把合结构，实现了工作台端径跳达到0.02毫米的高精度；解决了900吨重20米跨距龙门架进给同步的难题，实现了龙门架高精度同步控制；解决了车铣复合刀架既能高转速又能实现大扭矩的铣、镗、钻加工的难题，同时利用拉刀主轴和四个角油缸技术，增加连接刚度，解决了既可抓取工具柄又可抓取附件头的难题。
  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.
