Abstract

The invention provides the rapid steel inlaid spiral cutter with good wear resistance. The rapid steel inlaid spiral cutter with the good wear resistance comprises a cutter head and a spiral rod, reinforcing ribs are arranged on the outer surface of the spiral rod, flowing holes are formed in the reinforcing ribs, spiral teeth are arranged on the outer surface of the spiral rod, and a chip removal channel is formed between every two adjacent spiral teeth. According to the rapid-steel-inlaid spiral cutter with the good wear-resisting performance, the wear-resisting strips arranged on the rapid-steel-inlaid spiral cutter and the spiral teeth can synchronously rotate, the hole diameter is expanded and ground, grinding friction force is buffered and prevented from directly acting on the surfaces of the spiral teeth, the wear-resisting performance of the rapid-steel-inlaid spiral cutter is improved, and the service life of the rapid-steel-inlaid spiral cutter is prolonged. And the situation that when hard impurities exist in a machined part, the impurities make contact with and rub against the surface of the tool under continuous pushing of an operator, the friction force of the tool is increased, and the tool is prone to being damaged in the friction process is avoided.

Description

technical field [0001] The invention relates to the technical field of an inlaid steel helical knife, in particular to an inlaid steel helical knife with good wear resistance. Background technique [0002] Inlaid steel spiral knife refers to the spiral knife made of inlaid steel as raw material. [0003] When using the inlaid steel spiral knife, through its high-speed rotation, the surface of the workpiece is drilled to meet the production needs. [0004] In the related technology, during the drilling process, through the friction between the cutter head and the workpiece, a large amount of waste chips will be produced, and the drill hole will be gradually formed. When there are hard impurities, under the continuous advancement of the operator, the impurities will contact and rub against the surface of the tool, which will increase the friction of the tool and easily cause the tool to be damaged during friction. [0005] Therefore, it is necessary to provide an inlaid stee...
