The functional component of machine tool of our country numerical control although from " small " , " form a complete set the position of " promotes " crucial post " is taken seriously, but it is to be in all the time " " of heavy lead plane, light form a complete set, "" of small land of the seas and oceans is boat of travel of the against the current in such big environment, hard grow.
The Chinese Academy of Engineering person needle of Li Peigen Ceng Yi sees blood remind: "Long-term since we are insufficient to functional component attention, on functional component attempt and accomplish nothing makes very hard a step, the functional part that buys abroad can make our industry lacks competition ability only.
Is total a secretary in charge of sth of Wu Bailin of association of tool of Chinese machine tool long say: ? δ of wooden tablets or slips for writing of of graceful press and smooth of badger of of Xian of palpitate of Quan exemplaries of grave of chasm of cheek of the that take an examination of dried meat what egg of of ⒉ stepping on steps on thinking of extroversion of? of Suan of serve of part of the day of ticket Yao is inertial still spreading, to foreign brand idolatrous with a variety of apprehension to product of country of choose and buy, make the machine tool of high-grade numerical control of many new research and development is mixed in a lot of project invite public bidding, encounter admittedly by repellent, confined unfair treatment. The personage inside course of study points out: Purchase the entrance function part of high additional cost in great quantities, make numerical control machine tool overall become a vehicle of about 70% " outflow of fat water " . And now, can have produced part of certain and high-grade function when our country when, certain home user does not approbate not buy it however. Of functional component change independently, industrialization, those who be badly in need of policy give aid to energetically, be badly in need of the care of the user and support, be badly in need of home market help motive force.
Well-known, if the core of the major project such as machine tool of high-grade numerical control and national defence war industry equips, its are homebred change leading is national comprehensive strength to reflect. Review the development contrail of manufacturing industry of each country equipment, the country such as heart, day is powerful nation of numerical control machine tool, on one hand they have solid base, own the system of functional component form a complete set of world brand; On the other hand native government gave strong support, these countries made a lot of code drive and protect equipment manufacturing industry, some returns a machine tool of high-grade numerical control and core function component to bring into " " of case protection industry.
Tell objectively, western country starts early, science and technology develops, actual strength is abundant, lead position is in in product function and dependability respect, but also be by no means perfect. Investigation shows, entrance function component often also appears in respect of Wu of kimono of precision, function, dependability problem; is right of foreign goods adore often contain blindness and one-sided sex.
Recently, national hair changes appoint wait for 9 ministries and commissions to issue an announcement jointly: The government invests a project to belong to a government to purchase, outside dividing special situation, ought to purchase native product; this is pair of homebred equipment and crucial part suffer discrimination for a long time in open market, still " China makes " with " national pay " creates fair competition necessary policy of the environment measure.
To solve the commercial problem of product of high-end function part, should raise it above all in the user " acknowledge is spent " and " " of degree of belief. Production enterprise should establish close cooperative relationship with the user, be in " the overall function of lead plane of the have a thorough grasp in " of whole process service and individuation are special functional demand, and the function that the user cares most, quality and dependability problem, through " cooperative research and development, collective function experiments, try out, improve perfect finalize the design, the quantity produces " a such processes, stride a stage jointly (set) doorsill, in collaboration in interacting, use door from dare buy love to use long-term cooperation form a complete set, implementation advocate complementary double win to develop in all.
What import crucial function part to change home market to be opposite is excessive depend on, proposal association assists a government to be in charge of what the branch makes crucial function part as soon as possible to purchase directory through thorough investigation and study, the product in this catalog should stabilize batch production, its precision and function index should be approbated through expert appraisal, authoritative branch. In the meantime, to promote homebred change, every imports home to be able to produce abroad to be the same as the norms, coessential product that is the same as precision, should cancel the privilege to importing custom duty.
In addition, to the machine tool of high-grade numerical control that home develops and major equipment, in evaluating appraisal the proposal increases " the adoption of system of homebred numerical control and crucial function component leads " such assess index is encouraged introduce native product.
Our country rolls functional component industry is local born and bred nation industry, having 40 old development histories, although the industry is small (many about 60 enterprise) however one is approve from on century 60 time " grow in " of encounter of whole nation of accurate machine tool the mainstay business that rise. Be about the same in the respect such as establishment of scale of production, hardware and foreign person of the same trade. Make in accurate whorl with detect side of product of train in excess specified length of technology of technology, heavy-duty and cast-iron platform, large burden is returned even have stronger dominant position. For example: Can guide screw of ball of high accuracy of class of batch production P1-P2 deputy; The diameter is more than 100 millimeter, more than 10 meters whole exceeds length guide screw of long large ball deputy with ball of burden of big norms high accuracy linear slideway deputy; Guide screw of ball of high speed of nicety of P3 class above deputy roll with accurate high speed linear slideway deputy; The product of component of tall reliable scroll that is used at the special domain such as aerospace, nuclear power plant, Gao Tie; Management company still built center of research and development of scroll function component and project lab early or late.
