The Numerical Control Technology Transform For CA6140Lathe

Numerical control machine tools is the integrated products of typical electromechanics includes computer,automatic control,automatic detection and exactitude mechanical manufacturing technology etc.The engineering level of numerical controlled machine tools and owning amount have already become one of the important signs of weighing a national industry’s modernized level.The current development of numerical controlled machine tools in China is the only way for technological transformation of mechanical manufacturing’s the basis of factory automation in the future. At present, with the national policy to develop the introduction of the equipment manufacturing industry, advanced manufacturing technology has been widely applied to industrial, civil and other fields, as the major equipment manufacturing technology production equipment, the demand for CNC machine tools will be greatly enhanced.China’s current total of about400machines million, of which only the total number of CNC machine tools more than20million units of CNC machine tools of a very low rate. Ordinary lathe machining accuracy have been far from enough to meet the requirements of advanced manufacturing technology, if the purchase of new CNC machine tools to replace, it is clear the enormous cost, not in conformity with national conditions. Therefore, the use of CNC machine tool technology for the transformation of the existing line with the country’s industrial policies. As for the enterprises to rely solely on the purchase of new CNC machine tools, required a larger initial investment, with the result that many enterprises, especially small and medium-sized private enterprises very difficult. And replaced with the machine idle will lead to wastage. If the old CNC machine tools for transformation, and its low investment and quick returns, in the short term to increase the rate of China’s NC Machine Tool an effective way.CNC machine tool is mainly directed against the transformation of numerical control systems, servo systems, control systems and auxiliary hydraulic system transformation. CNC machine tools as a result of the integration itself is electro-hydraulic, structural complexity of the products, whether in the transformation of the standard method of calculating in accordance with the terms, whether or not in accordance with the rules of the transformation program and asked to select the type of components is to determine the performance of the modified machine, run accuracy, processing quality and reliability of the key factors.This subject comes from the common lathe numerical control transformation project of Liaoning Technical Institute of Economic Vocation. This thesis has explained thought and method of NC transformation of CA6140common lathe from machinery and electric two respects on the basis of summarizing state of development of NC technology.
