导轮是数控线切割机的重要零件,它的使用寿命及结构,对机床加工精度,产品光洁度和生产效率都有直接影响。目前,线切割机床的导轮,大部分采用合金钢,其加工工艺复杂,寿命短。由于高铝瓷具有耐磨、绝缘强度高等优点,因此进行了高铝瓷片导轮的试制,初步做出了结果,各项技术参数均基本达到金属导轮的要求。 The guide wheel is an important part of CNC wire cutting machine, its service life and structure, have a direct impact on machining accuracy, product finish and production efficiency. At present, the guide wire cutting machine tools, most of the alloy steel, the processing complexity, short life. As the high-alumina porcelain has the advantages of wear-resistant, high dielectric strength, so the high-aluminum ceramic guide wheel trial production initially made the results of the technical parameters are basically reached the requirements of the metal guide wheel.
