利用自制的交流磁化装置对W6Mo5Cr4V2高速钢刀具进行了磁化处理，并在通用机床上使用经磁化处理的高速钢刀具及未经磁化处理的高速钢刀具进行了切削实验，实验结果表明：与普通高速钢刀具相比，经磁化处理后的W6Mo5Cr4V2高速钢刀具，其切削工件表面粗糙度得到改善。同时，磁化时间及磁化频率应视为磁化处理中的关键调节参数，不同磁化时间及频率下的W6Mo5Cr4V2高速钢刀具的切削性能有所不同，在低频下的效果更好。另外，实验结果也表明：经交流磁化处理的W6Mo5Cr4V2高速钢刀具能够降低切削过程中的切削力并抑制积屑瘤的产生，从而增加刀具的使用寿命并提高刀具的加工质量。

The W6Mo5Cr4V2 high-speed steel tool was magnetized by the self-made AC magnetization device. Cutting experiments were carried out in a general purpose machine with the magnetized high-speed steel tool and non-magnetized high-speed steel tool. The experimental results indicated that the cutting surface roughness of the workpiece improves by the magnetized W6Mo5Cr4V2 high -speed steel tool. The magnetization time and magnetization frequency should be regarded as key magnetization adjusting parameters. The magnetized W6Mo5Cr4V2 high-speed steel tool show differentiated cutting performances under different magnetization time and frequency. More favorable properties were demonstrated in low frequency. The cutting force could be reduced during the cutting process by using of the magnetized W6Mo5Cr4V2 high-speed steel tool and the formation of the built-up edge in the tool could be inhibited, thereby the tool life was prolonged and the processing quality was improved.
