林业机械常用的零部件和木工机床刀具的耐磨性较低,使用寿命偏短是林机和木机制造中的一个突出问题。用脉冲电磁场对这些机件和刀具进行处理,以提高其使用可靠性,是一种新的简便而有效的方法。所用磁场的脉冲频率一般为0.5～1.5周/秒,磁场强度要求也不很高。其工作原理是:电磁脉冲使被处理的机件产生电 Wood-based machinery parts and woodworking machine tool wear resistance lower, shorter life expectancy is a prominent issue in the manufacture of wood and wood machines. Using pulsed electromagnetic fields to process these parts and tools to improve their operational reliability is a new and easy and effective method. The pulse frequency of the magnetic field used is generally 0.5 to 1.5 weeks / second, the magnetic field strength requirements are not very high. Its working principle is: Electromagnetic pulse to be processed by the machine to generate electricity
