Effects Of Magnetization On The Performance And Residual Stress Of Tool

The tool’s performance and service life have always been paied close attention on by the manufacturing sector. We all known that the the strength and wear resistance of the tool has the decisive role in manufacturing precision and efficiency of the product. At the same time, the tool’s performance and service life have a greater impact on the product’s processing costs, thus increasing wear resistance and tool life has always been valued by the relevant industry and research institutes.Existing methods to improve tool’s life can be used right now are optimize structural parameters, covering special layer on tool’s surface, using new materials and tool’s magnetic treatment. To be compared with other methods, magnetic treatment can cost least, combined with its relatively simple operation and high time efficiency, its has got more and more attention.Based on the efficient, low-cost, significant effect and simple operation of tool’s magnetic treatment, also combined with today’s existing research of tool’s magnetic treatment, we have done further research and analysis of tool’s magnetic treatment in this article. Taking magnetic voltage, magnetic time and demagnetization time as three parameters, we confirmed the best combination of this three parameters through orthogonal optimization experiments. At the end we developed a automatic magnetization treatment device which can be controlled by magnetic voltage, magnetic time and demagnetization time.The effects of magnetic device developed in this paper have been tested by corresponding experiments. By analysis of the experimental results, we can found that the magnetic treatment device has a significant effect in improving tool’s own performance, internal residual stress and the strength of the tool.
