[0002] With the increasing demands for processing efficiency and quality in modern manufacturing, high-speed milling technology has become an important means of precision machining. However, the cutting heat, cutting forces, and vibrations generated during high-speed milling severely restrict processing efficiency and tool life. Currently, the industry mainly addresses these challenges by optimizing tool geometry, improving tool materials, and introducing coating technologies. Nevertheless, how to effectively reduce cutting forces, ensure smooth chip removal, and actively suppress vibrations under high-speed cutting conditions remains a major challenge for milling cutter technology.

[0003] Specific solutions in existing technologies: Common solutions in existing technologies include symmetrical chip flute design, equidistantly distributed cutting edges, solid carbide tool bodies, and single-coating technology. While symmetrical chip flute design is simple to machine, it has low chip removal efficiency; equidistantly distributed cutting edges lead to concentrated cutting forces, which can easily cause vibration; solid carbide tool bodies have high hardness, but poor vibration damping performance; and single-coating technology struggles to balance high hardness and good interfacial bonding strength.

[0028] 1. The chip-breaking and vibration-damping end mill described in this application, by setting the end mill body, has two sets of asymmetrical deep chip-collecting grooves with shallow chip-collecting grooves during the milling process, which can simultaneously accommodate large-sized chips and guide fine chips out. Moreover, the unevenly distributed cutting edges forcefully break the chips and disperse the cutting force. At the same time, the damping cavity generates reverse sound waves to cancel out vibration energy in a specific frequency band, and the composite coating avoids interface stress concentration through a gradient transition layer, improving the coating bonding strength, thereby effectively improving the machining efficiency of the end mill body.

[0029] 2. The quick-release chip-disassembly and vibration-damping end mill described in this application, by setting a quick-release mechanism, allows the cutter body to be inserted into the insertion slot on the cylindrical cutter holder via a cylindrical insertion block when the cutter body needs to be installed. Rotating the rotary knob drives the horizontal shaft to rotate. The rotation of the horizontal shaft, under the action of two first bevel gears, drives the rotating shaft to rotate. The rotation of the rotating shaft drives the driving bevel gear to rotate. The rotation of the driving bevel gear drives four driven bevel gears and four threaded pins to rotate simultaneously. The rotation of the threaded pins, under the action of the internal threaded sleeve, causes the L-shaped locking block to automatically move towards the center and insert into the locking slot on the cylindrical insertion block, achieving automatic and rapid locking of the cylindrical insertion block, thereby realizing the quick installation of the cutter body.

[0030] 3. The quick-assembly and disassembly chip-dispersing and vibration-damping milling cutter described in this application, by setting a clamping mechanism, during the process of rotating the shaft and driving the four threaded columns to rotate simultaneously, the rotation of the shaft drives the extension shaft to rotate. The rotation of the extension shaft drives the bidirectional lead screw to rotate under the action of two second bevel gears. The rotation of the bidirectional lead screw drives the two rectangular sliders to move to both sides simultaneously, thereby driving the two push rods to push the lifting plate, causing the lifting plate to move downward. The clamping spring clamps the clamping plate, so that the clamping plate clamps against the top of the cylindrical plug block, thereby achieving effective clamping after locking the cylindrical plug block, effectively ensuring the stability of the cylindrical plug block in the plug groove.

[0031] 4. The chip-disassembly and vibration-damping end mill described in this application, by setting a sealing mechanism, can compress the telescopic airbag in the locking groove during the process of the L-shaped locking block entering the locking groove, so that the air in the telescopic airbag enters the annular sealing airbag through the connecting pipe, causing the annular sealing airbag to expand and press against the inner wall of the insertion groove, thereby effectively sealing the gap between the cylindrical insertion block and the insertion groove and preventing chips from entering the gap.
