Commonly Used Milling Cutters On CNC Machine Tools

1. Face milling cutter. The circumferential surface and end face of the face milling cutter have cutting edges, and the end cutting edge is the secondary cutting edge. Face milling cutters are mostly made of sleeve-type tooth insert structure. The cutter teeth are made of high-speed steel or carbide, and the cutter body is 40Cr.
2. End mill. The end mill has cutting edges on its cylindrical surface and end face. They can be cut simultaneously or separately. The cutting edge on the cylindrical surface of the end mill is the main cutting edge, and the cutting edge on the end face is the secondary cutting edge. Note that because there is a groove in the middle of the end face of the end mill, axial feed is not possible.
3. Mold milling cutter, its structural feature is that the ball head or end face is covered with cutting edges, the circumferential edge is connected with the ball head edge in an arc, and can be fed in radial and axial directions.
4. Keyway milling cutter, which has two cutter teeth, both the cylindrical surface and the end face have cutting edges, and the end face edge extends to the center. During processing, first feed axially to reach the groove depth, and then mill out the entire length of the keyway along the direction of the keyway.
5. The drum-shaped milling cutter has its cutting edges distributed on an arc surface with a radius of R, and there is no cutting edge on the end face. By controlling the up and down position of the tool during processing, and corresponding to the cutting part of the blade, different bevel angles from negative to positive can be cut on the workpiece. The smaller R is, the wider the bevel angle range that the drum milling cutter can process.
6. Forming milling cutters are generally specially designed and manufactured for specific workpieces or processing content.
