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.
