Do not master core technology, machine tool of high-grade numerical control uses the numerical control system of the entrance and functional part. Restricted lead plane badly to make technical progress. And, use the functional component of the entrance and numerical control system in great quantities, the space that leader plant depreciates is very little, so, although the product structure of domestic machine tool and amount rose but profit was not carried, this is a very main reason. Accordingly, raise functional component research and development ability and production level, accelerate process of functional component industrialization to already became the issue that current and urgent need tries to take seriously and be solved, the Chongzhongzhi that also is industry industry structural adjustment is heavy.
Current, the analyst inside course of study thinks. Development of whole of industry of machine tool tool is swift and violent, the demand of machine tool accessory fast add, space of home market development is larger. Especially in last few years, country the rapid development of auto industry, promoting the growth of machine tool industry and demand of machine tool accessory. Current, product of level of technology of high end of machine tool accessory lacks the country, basically count an import, cheap product basically produces a business by home in occupational. But in last few years, as Taiwan area product a large number of swarming into, intermediate competition of market of product of accessory of numerical control machine tool grows in intensity.
Be compared with phase of plant of machine tool leader and character, measure of industry of accessories of domestic machine tool is at present more, besides one local and state-owned company, dimensions of most business presence is lesser problem. The respect such as performance of the equipment precision that produces a business, equipment is put in the difference of certain level. Current, industry of machine tool accessory puts the country in main problem to new product invests development strength sale of insufficient, product joins the level remains to rise further, company producer still needs to strengthen to product quality awareness, increase what carry product policy to on any account to adjust etc.
Technical progress is very rapid also. But do not return with ratio of photograph of foreign person of the same trade very big. Main reason has: The political environment that is industrial development and past is concerned, development of dimensions of company of production of component of our country machine tool is rapid in recent years. Level of past state support is insufficient, and the thought of industry too eager to be successful that one sees only the immediate advantage is serious, cause heavy lead plane, small part. 2 it is scientific research investment little, foundation is feeble.
Domain of a few crucial parts, for example. A few enterprises also can be done, but the functional part that makes high accuracy with general accuracy machine tool, these products also can be used in a few high-grade numerical control above the machine tool, but the stability of precision and hold to a gender to be no good, plus the problem of raw material and craft level problem. Family abroad’s advanced component can be not changed with 3 years, and domestic component perhaps can be used to a year to have to change this partly only also is to cause market of homebred function component to have the reason with low rate.
All sorts of policy also the development that huge is urging company of machine tool fittings, financial crisis produced very far-reaching effect to industry of our country machine tool. Encourage often seek progress in the crisis, because get the influence of economic crisis, market of machine tool fittings is overall and atrophic, the requirement of the user more strict, plus abroad the competitive pressure of enterprise of each big machine tool, make home faced very big risk about business market. Think inside course of study, want to finish future of industry of tool of Chinese machine tool 3 years to promote program goal, namely home market of homebred machine tool is had rate raise 70% above, among them numerical control machine tool is had rate raise 40% above, need the form a complete set that raises machine tool of homebred numerical control is led, this is the biggest bottleneck that restricts development of machine tool lead plane.
Home market of homebred machine tool is had rate raise 70% above, wu Bailin emphasizes saying. Numerical control machine tool is had rate raise 40% above, this target is very arduous. Crucial part, fittings is deciding the development of lead plane, closed development of key component, fittings to go up only level, of crucial function component deserve to lead the machine tool of large numerical control that raised ability to form a batch to have stronger competition ability in the world to create a company oneself, ability weighs the country to go up is production powerful nation, just still make big country at present.
Detect for example contact sensor of the position, want to use many sensor in the course that the machine tool produces additionally. Be close to switch, detect sensor of the sensor of the type that suppress report of pressure, the type that control block and capacitance type sensor, still have infrequently the pyroelectricity shade sensor that gives priority to with platinic, copper, thermal resistor sensor that gives priority to with semiconductor material and thermocouple sensor wait. On numerical control machine tool, temperature sensor is used detect temperature undertakes temperature makes up for overheat protection thereby. The machine tool produces a process to wait for yuan of parts of an apparatus to be a foundation with sensor, also raise taller requirement to sensor.
At present Chinese auto industry is the main body that the machine tool consumes, according to statistic. The machine tool occupies the 2/3 left and right sides that automobile factory fixed assets always invests, among them car component treatment is compared to the demand of the machine tool truckload the factory wants big decuple left and right sides, 70% what take demand of automobile industry machine tool about. After 3 years, get Chinese automobile industry is many and unused produce the effect that can reach large-scale annex to recombine, chinese car machines an industry to will drop gradually to the demand of the machine tool, the machine tool of its demand also will more environmental protection and efficient. The demand of the machine tool rises the requirement that all sorts of sensor demand such as sensor of switch, rotate speed, pressure sensor and quality are close to related farther also promotion.
Component of numerical control system, function and cutting tool photograph present serious lag state to developing at lead plane, the industrial catenary of industry of tool of whole machine tool and its industry structure also put the state in the unreasonable phenomenon with serious move. Be told relatively at lead plane, component of numerical control system, function and cutting tool are in strong ” and ” big ” the respect fares badly, still have very big difference with the enterprise of current world level and even Chinese Taiwan. This is in what there is machine tool of our country high-grade numerical control on certain level to be able to develop continuously, need the height that causes concerned leader takes seriously.
