Abstract
Taking account of the situation of many old-fashioned imported machine tools, this paper proposes some favourable methods of rebuilding equipment. In theory and practice, with full digital electric system of modern automation technology, rebuilt equipments are easy to operate and reduce energy consumption, raise production efficiency. It realizes the aim of Environment-friendly and resource-economical. In this paper, it also gives three typical examples of rebuilding equipment, table planning machine made in Germany, D2300 lathe and 745A slotter made in Russia. Some pragmatic issues have been discussed, e.g. design optimization for speed regulation of main drive, position finding of cutter frame and synchro control between lathe tools feeding and lathe chuck turning. Finally, it gives the results of the operational curves of rebuilding equipment and relevant data.
