In CNC machining, end mills are versatile cutting tools with a wide range of applications. The following are the main uses:Surface MillingFlat Surface Milling: End mills are used to machine flat surfaces on workpieces. For example, in the production of mechanical parts such as engine blocks and machine tool beds, end mills are used to mill the upper and lower surfaces to ensure flatness and surface roughness requirements, providing a good foundation for subsequent assembly and processing.Profile Milling: They can mill various complex profiles. In the manufacturing of automotive parts, such as the outer contours of car door panels and hoods, end mills can precisely machine the designed profiles according to the CNC program, improving production efficiency and part accuracy.Groove MillingKeyway Milling: In the production of shafts and gears, end mills are often used to mill keyways to ensure the accurate connection and torque transmission between components. For example, in the gearbox m...

End mills are essential for precision work in CNC machining due to several key factors related to their design, material, and performance. The details are as follows:High Precision DesignAccurate Geometry：End mills have precisely ground geometries, including the diameter, helix angle, and cutting edge shape. This ensures that they can remove material with high accuracy, enabling the machining of complex shapes and tight tolerances. For example, in the aerospace industry, where components like turbine blades require extremely precise shaping, the accurate geometry of end mills allows for the production of parts that meet strict dimensional and surface finish requirements.Sharp Cutting Edges：The sharp cutting edges of end mills can make clean and precise cuts. They can effectively shear off material without excessive tearing or deformation, which is crucial for achieving smooth surfaces and accurate dimensions. In the production of optical lenses, for instance, the sharp edges of...
