2、大障碍就是添置设备的初期投资大,这使许多中小型企业难以承受。如果淘 汰大量的普通机床,而去购买昂贵的数控机床,势必造成巨大的浪费。因此,普 通机床的数控化改造大有可为。改造旧机床、配备数控系统,把普通机床改装成 数控机床也是提高机床数控化率的一条有效途径。 关键词:数控改造,主轴,可编程控制器,进给系统,传动系统 4 ABSTRACT CNC technology level and CNC equipment have much to measure a country has become an important symbol of modern industry. CNC machin
3、e as the typical electromechanical products, machinery manufacturing plays an enormous role, very good solution to the complex structure of modern machinery manufacturing, precision, small batch and changeable parts processing, and stable product quality can greatly improve the production efficiency
4、. However, the development of numerical control technology is the biggest obstacle to acquire the initial investment of equipment, which many small and medium enterprises to bear. If the elimination of common tools, and to buy expensive nc machine tools, will cause enormous waste. Therefore, the reform of the CNC lathes. Reforming the old machine, CNC system with the ordinary CNC machine is converted
