In the area of manufacture, the life of the tools is related to production costs directly. The useful life of the tools can be extend through magnetic treatment. Designing a machine which can magnetic treatment for tools base on AVR and manufacturing it. The machine can provide hardware platform to explore the mystery to magnetic treatment for tools. In this paper the principle of the machine will be introduced. The structure and the principle both of the main and the control circuits internal the machine will be mentioned too. Confirmed the MCU of AVR Series can be used in the field of the magnetic treatment. In the end. Test the waveform on the main circuit which can prove the machine can be used fulfilling the design requirements.%在机械加工领域,刀具的使用寿命直接关系到生产成本.通过磁化,可延长刀具使用寿命.设计制造一台以AVR系列单片机为控制核心的刀具脉冲磁化机,可为刀具磁处理提供硬件平台.具体阐述了磁化机的设计原理和磁化机内部主、控电路的结构及其原理,证实了AVR系列单片机在磁化机中应用的可行性,最后通过测试主电路中输出端口的波形对磁化机进行验证.
