Abstract

The invention belongs to the field of cutters and particularly relates to a four-edge cutter with good centering effects. The four-edge cutter comprises a handle. The four-edge cutter is characterized in that: one side of the handle is provided with a cutting part, the front end of the cutting part is provided with a centering part, the cutting part and the centering part are provided with four cutting edges, and the surface of the cutting part and the surface of the centering part are provided with a tungsten steel coating. The four-edge cutter adopts the centering part disposed at the end of the cutter to center the cutter and to prevent cutter shift caused by external force in a cutting process, thus ensuring machining precision of the cutter and improving product quality.

Description

technical field [0001] The invention belongs to the field of cutting tools, in particular to a four-edged milling cutter with good centering effect. Background technique [0002] The end face of the existing milling cutter is generally flat, and it is easy to shift due to the influence of cutting resistance during the cutting process, resulting in errors in the processed holes, affecting subsequent processing and assembly, resulting in defective products, and negatively affecting the image of the enterprise. affected. Contents of the invention [0003] The present invention aims at the deficiencies of the prior art. The present invention sets a centering part on the front part of the milling cutter, overcomes the inaccurate centering of the existing milling cutter, ensures the precision of processing, and improves the quality of the product. [0004] The present invention is realized through the following technical solutions: [0005] Four-edge milling cutter, which incl...
