Research And Implementation Of Numerical Controlled Remanufacturing Technology For Spiral Flute Electrolytic Tool Grinder

In recent years, with the rapid development of metal cutting technology and cutter technology in our country, more and more hard alloy revolving cutters, especially the total hard alloy revolving cutters are used. So more requirements are demanded. The processing of spiral flute is the key working procedure during the course of machining total hard alloy revolving cutter. Which greatly influence the performance of a cutter. At present, the special equipment for processing the spiral flute is universally lagged in the tool machining industry in our country. This leads to bad processing quality and low processing efficiency of the spiral flute. Thus it becomes a bottle-neck problem of restricting enhancing the processing quality and processing efficiency of the cutter. Based on the thinking of equipment numerical controlled remanufacturing, how to turn the ordinary electrolytic tool grinder which left unused into the special equipment for processing the spiral flute by numerical controlled remanufacturing technology is researched in the paper. It is of biggish practical meaning to both enhancing the processing quality and processing efficiency of the spiral flute and making enterprise stock assets to be used efficiently as the increment.At first, the structure and work principle of ordinary electrolytic tool grinder is introduced in the paper. The current actuality and problem of processing the spiral flute in total hard alloy revolving cutter is analyzed. Based on this, an idea of resolving the spiral flute processing problem is proposed. That is putting the numerical controlled remanufacturing technology into the electrolytic tool grinder.In succession, the total scheme on numerical controlled remanufacturing is established. The transmission part of machine tool is remanufactured, such as the guide-way, transmission mechanism, drive mechanism for X-axis of work-stable, mechanism for grinding wheel up and down, mechanism for workpiece rotation and automatic indexing, and so on. And based on the principle of open architecture CNC system, the development scheme on the special CNC system for processing the spiral flute is fixed on.Based on the above research, the hardware and software system of the CNC system is designed. Enhancing the precision of returning machine origin by changing the disposal and installation way of the sensors is discussed. At same time, the idiographic implementation approach of the spiral interpolation arithmetic is researched. And the...
