Integral carbide goldfish scale milling cutter

Abstract

The invention discloses an integral carbide goldfish scale milling cutter used for milling and processing composite materials such as carbon fiber, glass fiber and the like. The milling cutter of the invention comprises a milling cutter blade and a milling handle, wherein the cutting blade on the milling cutter blade is a cutting unit formed by left and right-handed rotation symmetrical staggered spiral grooves, and the number of the left spiral groove is two more than that of the right spiral groove; the length of the cutting blade of each cutting unit is 0.05-0.1mm, and the width of the rear cutter surface of the cutting blade along the cylinder surface is 0-0.01mm; the anterior angle of the cutting blade is 10-15 degrees, the front cutter surface is a straight line on a normal plane; the relief angle of the cutting blade is 20-25 degrees; the depth of the spiral cutter groove is 7-8% of the diameter of the cutter. The invention has the advantages that the cutting blade of the integral carbide goldfish scale milling cutter is composed of a plurality of cutting units and is sharp, which greatly lowers cutting resistance and realizes high speed cutting so as to obtain the effect of using milling for replacing abrading, so that the processing efficiency and the surface quality of the composite materials can be improved, and the service life of the milling cutter can be prolonged.

Description

Technical field: [0001] The invention is a milling cutter for milling composite materials such as carbon fiber and glass fiber. Background technique: [0002] Composite materials such as carbon fiber and glass fiber are very difficult to process. The plastic deformation of the material is difficult and the heat dissipation is also poor. Delamination or wire drawing phenomenon; while the existing milling tools for composite materials are mainly helical edge overall alloy or high-speed steel end mills, the continuous long cutting edge makes the cutting edge not sharp, and finally, the existing processing tool cutting Poor performance, low processing efficiency, and short tool life; the surface roughness of the machined surface is low, and it is prone to delamination or spinning; it can easily meet the high-quality and efficient processing requirements of carbon fiber, glass fiber and other composite materials. Invention content: [0003] The purpose of the present invention...
