Title:
CUTTER MANUFACTURED BY USING PLASMA ADDITIONAL MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/252992
Kind Code:
A1
Abstract:
Disclosed are a cutter manufactured by using a plasma additional material and a preparation method therefor. The preparation method comprises the following steps: fixing a cutter blank to a clamp, so that a cutting edge of the cutter blank faces upward; melting an additional material arranged on the cutting edge by taking a plasma arc as a heat source, so that a cladding layer is formed on the cutting edge; carrying out thermal treatment on the cutter blank; and grinding, polishing and sharpening the cutter blank successively. The cutter is manufactured by means of the above-mentioned preparation method. The cutting edge of the cutter blank is provided with the cladding layer. The method not only facilitates the improvement of the hardness, sharpness and durability of a cutter, thereby indirectly prolonging the service life of the cutter, but also reduces defects such as slag inclusion of pores in a cladding layer, thereby further improving the hardness and sharpness of the cutter.
