Computer numerical control (CNC) milling cutter with four teeth

Abstract

The invention discloses a computer numerical control (CNC) milling cutter with four teeth. The CNC milling cutter comprises a metal handle and a cutter part, wherein the metal handle takes the shape of a cylinder, is placed horizontally, and is positioned on the right side of the CNC milling cutter; the cutter part of the CNC milling cutter is machined from a metal cylinder, placed horizontally, positioned on the left side of the CNC milling cutter, and conjoined with the metal handle of the CNC milling cutter; four end tooth bodies of the four teeth of the CNC milling cutter are uniformly distributed on the left end surface of the CNC milling cutter; an included angle I is formed between the cutting edge line of each end tooth body and the middle perpendicular line of the left end surface; each end tooth body comprises a front angle I, a first rear angle I and a second rear angle I; the tooth top part of each end tooth body protrudes from the left end surface of the CNC milling cutter, and an included angle II is formed between the tooth top part of the end tooth body and the left end surface of the CNC milling cutter; four circumferential tooth bodies of the four teeth are spirally and uniformly distributed on the cylindrical surface of the cutter part of the CNC milling cutter from left to right; a spiral angle is formed between the edge of each circumferential tooth body and the horizontal axis of the CNC milling cutter; each circumferential tooth body comprises a front angle I, a first rear angle II and a second rear angle II; and grooves are formed between each circumferential tooth body and the other three circumferential tooth bodies.

Description

technical field [0001] The invention relates to a four-tooth numerical control milling cutter, specifically a novel milling cutter suitable for use on a numerical control machine tool, having four teeth. Background technique [0002] Usually, due to incorrect design, unreasonable structure, and wrong size of ordinary milling cutters for processing metal materials, the milling process cannot meet the requirements, the product quality is poor, the grade is not high, the use value is low, and the service life is short. , so it is necessary to finely design, invent and innovate this ordinary milling cutter to form a CNC milling cutter with good processing quality, high-quality products, high utilization rate, correct design and reasonable structure, which can make the CNC milling cutter work Normal operation, good working performance and good running effect, so as to ensure stable work, high processing precision and long service life; overcome the design error and unreasonable s...
