Description

Technical Field

[0001] The utility model relates to the technical field of milling cutter equipment, in particular to a high-efficiency end mill with multiple milling edges. Background Art

[0002] End mills are the most commonly used milling cutter on CNC machine tools. They feature cutting blades on both the cylindrical and end surfaces, and they can cut simultaneously or independently. They are primarily used for plane milling, groove milling, step milling, and profile milling, and can also be used for face milling. However, due to their 90° lead angle, the force acting on the tool, in addition to the main cutting force, is primarily radial. This can easily cause tool shank deflection and vibration, impacting machining efficiency. Therefore, end mills are not recommended for machining flat surfaces without steps, except for special reasons such as thin-bottomed workpieces requiring low axial force or occasional face milling to reduce tool inventory.

[0003] An existing patent (publication number CN218135231U) discloses a high-efficiency end mill with multiple milling blades, comprising a first end mill, a second end mill, a cutter bar, a milling blade head, a fixing bolt, a clamping limit slot, a central through hole, a central reinforcing splint, a bolt, a nut, and an arcuate slot. The utility model has the following beneficial effects: multiple parts can be adjusted, which provides strong applicability and high flexibility, allowing the milling cutter to process two parts simultaneously. Furthermore, if the end milling end is damaged, there is no need to search for an end mill of the same model for replacement; the end mill can be directly re-engaged, making it convenient to use and saving time. The milling blade heads can be set at different heights and different processing angles, allowing the same part to be processed at different depths in one go. This greatly improves milling efficiency, thereby enhancing overall part processing efficiency and reducing processing costs, thus meeting people's needs when using end mills.

[0004] However, there are some problems in the use of the existing high-efficiency end mills with multiple milling blades: 1. The overall splicing and installation efficiency of the high-efficiency end mills with multiple milling blades currently on the market is low during use, which is not convenient for users to disassemble and install conveniently. The traditional end mills with multiple milling blades are troublesome to disassemble, which increases the overall inconvenience of use; 2. The high-efficiency end mills with multiple milling blades currently on the market lack an installation mechanism to enhance their installation when in use, which increases the overall installation time loss, and are prone to loosening during manual installation, resulting in the risk of falling off during work.
