Wave-edge end mill

Abstract

The invention discloses a wave-edge end mill. The end mill comprises a rod-shaped body, wherein the rod-shaped body is divided into a cutting part and a handle part; n chip grooves are formed in the cutting part; wave-shaped cutting teeth are distributed on a circumferential cutting edge and are distributed along the cutting part at a helical angle of 0-20 degrees; an axis liquid inlet channel is arranged at the position of the central axis of the rod-shaped body; and n bottom end liquid outlet channels and n circumferential liquid outlet channels are arranged in the cutting part, the number of the bottom end liquid outlet channels and the number of the circumferential liquid outlet channels are the same as that of the chip grooves, and the bottom end liquid outlet channels and the circumferential liquid outlet channels communicate with the axis liquid inlet channel separately. According to the wave-edge end mill, the problem that chips cannot be timely and effectively discharged in the metal cutting process, especially the high-speed cutting process can be solved, and the influence of chip accumulation on the cutting service life and performance of a cutter is prevented; and under the working condition that effective cooling cannot be achieved through external extensive cooling, timely and sufficient cooling of the cutting part of the cutter is achieved, and especially the excellent effect is achieved on cutter cooling under the working condition of deep cavity machining or complex machining.

Description

technical field [0001] The invention relates to the technical field of cutters, in particular to a wave edge end mill. Background technique [0002] Cutting tools are tools used for cutting in mechanical manufacturing. Since the tools used in mechanical manufacturing are basically used to cut metal materials, such tools are metal cutting tools. The end mill is one of the metal cutting tools. The end mill is also the most widely used milling cutter on the CNC machine tool. The end mill has cutting edges on the cylindrical surface and the end surface. They can cut at the same time. Cutting is done individually. [0003] When the cutting tool is performing metal cutting, the discharge of material chips has a great influence on the processing performance and service life of the tool, especially when the cavity is milled, the chips will accumulate in the cavity, which is difficult to discharge, and the accumulated chips will be Cause repeated cutting, the tool cannot effectivel...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a wave-edge end mill. Through structural improvement, it can solve the problem that chips cannot be discharged in time and effectively during metal cutting, especially high-speed cutting, and prevent chip accumulation from affecting the tool cutting. Life and performance are affected; and the cutting part of the tool can be cooled in a timely and sufficient manner under the conditions where the external extensive cooling cannot effectively cool, especially for tool cooling in deep cavity machining or complex machining conditions; at the same time, it can also Lean and Eco-Friendly for Machining Cooling
