CA6140普通车床微机数控改装设计(含全套CAD图纸).doc

物竞天择，适者生存。一些不适应社会发展在机床必将被淘汰，所以实施机床的数控 化改造是机械行业在必然趋势。通过搜集资料、实践研究等方法对机床就行改造即是用较 少的成本去创造更高的价值。而这也将极大的推动中国机械行业的发展。 经过大量实践证明普通机床数控化改造具有一定经济性、实用性和稳定性。所以很多 企业纷纷将现有机床改造成经济型数控机床，这种做法具有投资少、见效快的特点。事实 证明：机床的数控化改造可以为企业带來可观的经济效益。 目前机床数控化改造的市场在我国还有很大的发展空间，现在我国机床数控化率不到 3%。用普通机床加工出来的产品普遍存在质量差、品种少、档次低、成本高、供货期长, 从而在国际、国内市场上缺乏竞争力，直接影响一个企业的产品、市场、效益，影响企业 的生存和发展，所以必须大力提高机床的数控化率。本文以车床的数控改造为例，介绍丫 机床数控改造的方法，包括其结构的改造设计，性能与精度的选择以及最后改造方案的确 定。 关键字：CA6140机床、数控化、改造、设计 Abstract Natural selection, survival of the fittest. Have to adapt to social development will be eliminated in the machine，so the implementation of the transformation of CNC machine tools in machinery industry is an inevitable trend. By gathering information，practical research methods such as the transformation of the machine that is on the line with less cost to create higher value. And this will greatly promote the development of China’s machinery industry. After a lot of practice proved ordinary CNC transformation with a certain economy， practicality and stability. So many companies have transformed into an existing machine Economical CNC machine tools，this approach has less investment，quick features. Facts have proved that: NC transformation tools can bring considerable economic benefits for the enterprise. Currently CNC transformation of the market in our country there is still much room for development，is now China’s machine tool CNC rate of less than 3%. Out of the ordinary machining widespread poor quality products，less variety，low-grade，high-cost，long delivery period，so uncompetitive in the international and domestic markets, directly affect a company’s products，markets，effectiveness，impact business survival and development，it is necessary to greatly improve the rate of CNC machine tools. In this paper，CNC lathe transformation for example，describes a method of CNC transformation, including identification of the transformation of the design of its structure，the performance and accuracy of selection and the final transformat
