Description

Technical Field

[0001] The utility model belongs to the technical field of milling cutter discs, in particular to a milling cutter disc fixing seat. Background Art

[0002] A milling cutter is a tool used for metal cutting and is widely used on various machine tools (such as milling machines, machining centers, etc.). It removes material from the surface of the workpiece through high-speed rotation and feed motion to form the desired shape and size. The milling cutter is a disc-shaped milling cutter. Before use, the milling cutter needs to be fixed to the rotating part of the machine tool. The high-speed rotation of the rotating part of the machine tool drives the milling cutter to rotate to achieve the processing of the workpiece. The firmness of the connection between the milling cutter and the rotating part determines the subsequent processing efficiency and quality of the workpiece. A loose connection of the milling cutter may cause the milling cutter to loosen during the processing process, which may affect the processing accuracy of the workpiece and make the finished product quality of the workpiece poor. In addition, a loose connection of the milling cutter may cause disconnection during long-term use and high-speed rotation, which may cause some safety issues.

[0003] In summary, there are some problems in the use of the milling cutter disc fixing seat due to the loose connection between the milling cutter disc and the milling cutter disc, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
