Development of large machine tool castings is the foundation of our country high-end manufacturing

Large casting machine table is a focus of development in our country, is also a measure of the level of China foundry industry standard, one of the large casting machine table is a requirement for metal melting into accord with certain liquid is poured into the mold, after cooling solidification, men get a predetermined shape, size and properties of the casting process. Machine workbench has different characteristics with other technology, mainly is the adaptability, materials and equipment will be needed, pollute the environment. Casting production will produce dust and harmful gas and noise pollution to the environment, compared with other mechanical manufacturing process is more serious, need to take environmental protection measures to control it.

So large machine tool castings industry is the foundation of the development of high-end manufacturing industry in our country, and improve the national economy one of pillar industries, in May 2009, promulgated by the state council "the equipment manufacturing industry adjustment and revitalization of planning", specifically focusing on major technical equipment form a complete set of large castings. Large cast iron machine table as key components of major technical equipment, its internal stress, maintain ability of dimensional precision, rigidity, abrasion resistance and so on all have very high requirements. So, have relatively strict technical standards and safety norms, quality and reliability of the large machine table directly affect the service life of the form a complete set of host and operation performance.

According to the personage inside course of study, with the development of electric power, metallurgy, petrochemical industry, shipbuilding industry, the demand for large castings will continue to increase. The large machine table castings market demand will continue to rise. Although manufacturing machine tool castings has been committed to independent innovation in China, but with the developed country mature industry. In recent years, the strength of the incoming foreign high-end brand, is adding to the large machine table casting industry domestically in China. So the machine casting industry in China to gain a foothold in foreign markets, must fluctuate from the quality of the products.

The machine table of casting industry in China is moving to a new crucial period of development. Not only is this machine table casting industry development of a new beginning, new stage is casting industry from quantity to quality. So innovation is to promote to the machine table is an important driving force for the development of foundry industry, so innovation should not be ignored.

At present, the development of the workbench of the industry in China has made certain achievements, the continued stable development. A machine table industry in China market development speed in the progress, the output of machine table has been increased. But it is just our casting machine table industry achievements in industry, that does not make casting boring and milling machine table industry development in our country is the international casting machine table can't than. On the contrary, its development still faces some conditionality factors, among them, the lag of boring and milling machine table casting technology level is a big bottleneck, only break the bottleneck, the machine table industry is likely to make substantive breakthrough, will get rapid development in the steady development.
