Abstract

The invention belongs to the field of cutting tips and preparation methods thereof, in particular to a coated tip for processing aluminum materials and a preparation method thereof, the coated tip comprises a hard alloy matrix which is provided with a front tool face positioned at the top part and rear tool faces positioned at side parts, the front tool face and the rear tool faces are intersected for forming a cutting edge, the front tool face and any adjacent two rear tool faces are intersected for forming a tool nose, a coating which is polished and has low affinity to the aluminum materials is coated on the front tool face, and the rear tool faces are hard alloy ground surfaces after grinding; and the cutting edge is a sharp cutting edge which is not passivated and extends linearly. The preparation method comprises a plurality of steps of preparing the materials, pressing, sintering, forming, carrying out surface treatment and coating a coating, as well as polishing the front tool face of the tip obtained after the step of coating the coating, further grinding the rear tool faces for forming the sharp cutting edge and finally obtaining the coated tip for processing the aluminum materials. The cutting tip has the advantages of strong anti-adhesion and anti-abrasion capability, high processing efficiency, small processing cost, long service life and the like.

Description

technical field [0001] The invention relates to a cutting blade and a preparation method thereof, in particular to a coated blade for processing non-ferrous metals and a preparation method thereof. Background technique [0002] In the field of metal cutting, according to the characteristics of the processed metal, the processed metal is divided into P (steel), M (stainless steel), K (cast iron), N (non-ferrous metals), S (heat-resistant alloys and titanium alloys) and H (Quenched steel) Several categories. In the field of non-ferrous metals, aluminum has a large amount and a wide range. Its cutting characteristics are low melting point, good chip toughness, and aluminum chips are easy to bond on the upper surface of the rake face of the blade. The bonding of chips to the rake face will have the following negative effects: first, the rake face will be severely bonded and worn, and the flow of chips will be poor, resulting in increased cutting force and cutting heat, which wi...
