Description

Technical Field

[0002] A milling cutter head is a cutting tool specifically used for machining gears. A milling cutter head usually consists of a cutter head body, a cutter seat, cutting cutter teeth, etc. The cutter head body, as a supporting and fixing component, needs to be designed with sufficient rigidity and stability to withstand the huge forces generated during high-speed rotation and cutting. The cutter seat is used to install and fix the cutting cutter teeth to ensure that the cutter teeth can maintain the correct position and angle during the cutting process. When the milling cutter head is damaged and cannot be modularly disassembled and replaced, a series of serious problems will occur. Currently, maintenance personnel of milling machines will directly replace the damaged milling cutter head as a whole to achieve higher work efficiency.
