Uses of end mills

End mills can be used for face milling. However, because its main declination angle is 90°, the force on the tool is mainly radial force in addition to the main cutting force, which is easy to cause deflection and deformation of the tool bar, and also easy to cause vibration, which affects the processing efficiency. Therefore, in addition to similar to thin-bottomed workpieces Except for special reasons such as the need for small axial forces or the occasional reduction in tool inventory for face milling, end mills are not recommended for machining flat surfaces without steps.
CNC milling cutters can be divided into different types of milling cutters

1. Face milling cutter (also called end milling cutter): There are cutting edges on the circumferential surface and end face of the face milling cutter, and the end cutting edge is a secondary cutting edge. Face milling cutters are mostly made of sleeve insert tooth structure and insert machine clip indexable structure. The tooth material is high-speed steel or cemented carbide, and the cutter body is 40Cr. Drilling tools, including drills, reamers, taps, etc.;
2. Die milling cutter: Die milling cutter is developed from end milling cutter, which can be divided into three types: conical end milling cutter, cylindrical ball end milling cutter and conical ball end milling cutter. The shank has a straight shank. , Flattened straight shank and Morse taper shank. Its structural feature is that the ball head or end face is covered with cutting edges, and the circumferential edge is connected with the arc of the ball head edge, which can be used for radial and axial feed. The working part of the milling cutter is made of high-speed steel or cemented carbide.
3. Keyway milling cutter: used for milling keyway.
4. Forming cutter: the cutting edge is consistent with the shape of the surface to be machined.
