[0002] At present, the milling cutter used in mechanical processing is composed of a cutting blade and a tool holder. The cutting edge of the milling cutter has a single force in the feed direction, that is, a single curved or straight line on one cutting edge Shapes are all composed of a single cutting edge. The cutting method of this cutting edge has a large resistance, resulting in a large overall destructiveness, so it is prone to chipping and accidents, and it is easy to cause waste products and bring great losses. Serious and even casualty accidents It is generally understood that the smoother the surface, the higher the strength, and the new theory is that the surface with small gaps has higher strength, which does not reveal the essential structural characteristics of the material. Therefore, the existing hole processing tool efficiency Low, easily damaged, poor stability, poor drilling accuracy

Embodiment approach 1
[0034] Such as Figure 1-2As shown, the milling cutter of the first embodiment of the present invention has a tool shank and a tool head, the tool shank 1 and the tool head 2 are connected or formed as one, and the tool head 2 is integrally provided with a plurality of cutting blades 3. On each cutting blade 3, a face facing the cutting direction is a cutting surface 6, and the rear side or back side of the cutting surface 6 is a rear cutting surface 10, or a side cutting surface 11, and the cutting surface 6 and the rear cutting surface 10, or The side cutting surface 11 is intersected to form at least one cutting edge 8 or at least one side cutting edge 9. The compound milling cutter involves various concave and convex semicircular milling cutters, or various keyway milling cutters, or various T-shaped grooves Milling cutters, or various straight shank reverse dovetail milling cutters and various straight shank dovetail milling cutters, or various shell milling cutters, or v...

Abstract
The invention provides a milling cutter. The milling cutter is high in efficiency, large in strength and long in service life, and comprises a cutter handle and a cutter head, wherein the cutter headis integrally provided with multiple cutting cutter strips, and a cutting face is arranged on each cutting cutter strip; the milling cutter is characterized in that application with the millimeter strength of the milling cutter is carried out on the cutting faces of a rolling cutter, the strength of a cutting edge of the rolling cutter in the millimeter magnitude is at least increased by 50% or above, and the pressure intensity evenly born by the cutting faces of the rolling cutter in the millimeter magnitude can be increased by 50% or above.
Description
Technical field: [0001] The present invention relates to a kind of milling cutter, which is used in the mechanical processing of the gear production of machine tools, etc. The new machining theory believes that the cutting efficiency of the segmented cutting edge is high, but when the stepped cutting edge is gradually extended, the You will find that its effect significantly decreases until it disappears, so this theory is still not really a correct theory. Background technique: [0002] At present, the milling cutter used in mechanical processing is composed of a cutting blade and a tool holder. The cutting edge of the milling cutter has a single force in the feed direction, that is, a single curved or straight line on one cutting edge Shapes are all composed of a single cutting edge. The cutting method of this cutting edge has a large resistance, resulting in a large overall destructiveness, so it is prone to chipping and accidents, and it is easy to cause waste products a...
