Cyclone milling cutter with self-cooling lubrication structure

Abstract

The invention relates to a cyclone milling cutter with a self-cooling lubrication structure. The cyclone milling cutter with the self-cooling lubrication structure comprises a rotating base body and aplurality of thread milling blades; a large through hole is arranged on the rotating base body along the central axis; a plurality of base body connecting screw holes are arranged on the rotating base body along the circumferential direction; the plurality of thread milling blades in a circumferential direction is arranged on one end face of the rotating base body; and further includes a plurality of cooling lubricating fluid flow passages arranged in the rotating base body in the same number as the thread milling blades; an inlet of the cooling lubricating fluid flow passage is formed in theouter surface of the rotating base body and is away from the thread milling blades; an outlet of the cooling lubricant flow passage is formed in the inner circular surface of the rotating base body and is close to the thread milling blades; and an outlet of a cooling lubricating fluid flow passage is facing a nose of a thread milling blade. The base body, and the cooling lubricating fluid flow passages are all formed by 3D printing. The cyclone milling cutter with a self-cooling lubricating structure can not only directly cool the lubricating fluid but also directly acts on a cutting area, and has good cooling uniformity and low cooling cost.

Description

technical field [0001] The invention relates to a machining cutter, in particular to a whirlwind milling cutter with a self-cooling and lubricating structure. Background technique [0002] According to the processing type, the cutting process is mainly divided into: turning, drilling, milling, boring and grinding; [0003] Turning refers to the use of the rotary motion of the workpiece and the linear or curved motion of the tool to change the shape and size of the blank; drilling refers to the process of using the tool to process holes on the workpiece; The blade tool moves on the blank to cut the workpiece into the required shape and size; boring is a cutting process that uses a tool to enlarge a hole or other circular contours; grinding refers to the processing method of removing excess material on the workpiece with abrasives , which belongs to the finishing machining of mechanical processing; [0004] Threaded connection is a widely used detachable fixed connection, wh...

Problems solved by technology

[0006] The whirlwind milling cutter will cool the milling cutter during the machining process. The traditional cooling method mainly adopts the pouring (external cooling) method. This method uses a large amount of cutting fluid to pour in the cutting area to ensure the actual processing needs, but this lubrication cooling method There will be processing areas where the lubricating fluid cannot be cooled, and this kind of cooling lubrication is often due to the large amount of lubricating fluid used, resulting in high processing costs and affecting the accuracy of high-precision external threads
