| 摘要: |
| 大量老旧机床的报废将造成严重的资源浪费和环境污染。采用再制造技术可将废旧机床改造为新的数控机床。再制造的主要内容包括采用表面技术修复机床的磨损、划伤表面，恢复并提高机床的机械精度；采用滚珠丝杠、步进电机直接驱动提高机床的运动精度；采用数控系统替代原机床的电气系统，提高其控制精度。机床再制造最大限度地利用了原机床零部件的剩余价值，提升了机床性能，为老旧机床的升级换代找到了新途径。使再制造技术成为建立节约型社会的重要技术手段。本文介绍了老旧机床再制造的过程和表面工程技术在机床再制造中的应用。 |

| Abstract: |
| The discarding of a large number of used machine tools will lead to resource waste and environmental pollutions. The application of CNC-remanufacturing technologies can convert the used or waste machine tools to new ones with advanced control system. The main measures for remanufacturing include: (1) to repair the worn, flawed parts with surface engineering technologies to recover the mechanical precision; (2) to improve the kinematic accuracy with ball screw, new drives and motors; (3) to replace the original electric system with new CNC-controller to upgrade control accuracy. The remanufacturing of used machine tools makes full use of the residual values of parts, and greatly improves the performance of used machine tools. This makes it possible for remanufacturing technology to become one important means for establishing resources-saving society. The remanufacturing process of used or waste machine tools and the application of several kinds of surface engineering technologies are induced in this paper. |
