China cnc machine casting enterprises has been no consideration of this important properties, which should arouse the concerns of industry. In recent years China's machine tool industry has developed rapidly, not only increase production, but also some industrial countries merger of the old machine tool enterprises, but from the above-mentioned three aspects, as the machine of the casting has not been a corresponding increase in quality , But a landslide trend, with other industrial countries the gap is increasing. At present, China's output of great casting, casting its international competitiveness still needs to be strengthened. Our urgent task now is Fafentujiang, as soon as possible to change this situation, rather than chanting slogans and empty talk about "reached the international advanced level." States call for independent innovation in the circumstances, many companies linked to the "research and development centers," the brand, or some provincial centres, in fact even the basis of casting technology companies work not do anything, the situation should be such Tuyouxuming As soon as possible. To make our cnc machine quality reached the international advanced level at an early date, machine tool industry leaders abandon the hope that heavy cold light of the traditional concepts, and the enhancement of the quality of the casting To revitalize the industry a major task, to say that a revolution is also might not. Enacted as soon as possible on the casting quality requirements of the machine tool industry standards proposed to develop the machine before casting quality standards (such as JBn3997-1985, JB/GQ1021-1981, JB/GQ1022-1981) and the relevant national standards-based, in the light of foreign Machine Casting of the technical requirements, enacted as soon as possible with the current technology development requirements of the machine casting quality standards, in particular cnc machine casting. In the trial standards, amendments, should be vigorously implemented. Bills which do not meet the standard requirements of the foundry business and shall not accept orders for the machine tool castings. Do not meet the requirements of castings, will not be allowed for formal cnc machine products. Casting new standards on the quality requirements, should be slightly higher than the previous industry standard for good.
