Abstract
The W6Mo5Cr4V2 high-speed steel tool was magnetized by an AC magnetization device which made by ourselves, and the 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 could be improved by the magnetized W6Mo5Cr4V2 high-speed steel tool. Meanwhile the magnetization time and magnetization frequency should be regarded as the key of magnetization adjusting parameters. The magnetized W6Mo5Cr4V2 high-speed steel tool presented the different cutting performance under the different magnetization time and frequency, in which there were the better effects in low frequency. In addition, the experimental results also showed that 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.
