What are the common classifications of milling cutters?

1. According to the direction of the cutter teeth: it is divided into straight tooth milling cutter and helical tooth milling cutter

2. According to the tooth back form: divided into sharp tooth milling cutter and shovel tooth milling cutter

3. According to the structure: divided into integral type, welded type, insert type, indexable type

4. According to the purpose: divided into cylindrical milling cutter, face milling cutter, disc milling cutter, saw blade milling cutter, end milling cutter, keyway milling cutter, mold milling cutter, angle milling cutter, forming milling cutter, etc.

1. End mill

End mills have cutters on both the cylindrical surface and the end face, and they can cut simultaneously or individually.

2. Three side edge milling cutter

Three-sided edge milling cutter is referred to as three-sided edge for short: all three cutting edges have rear angles, the cutting edges are sharp, and the cutting is brisk. It is a standard machine tool tool, usually used on horizontal milling machines, and is generally used for milling grooves and steps.

3. Face milling cutter

The cutting edge of the face milling cutter is covered with the circumference and the end face, and the cutting edge of the end face is the auxiliary cutting edge. This kind of milling cutter has a large diameter, so the cutter teeth and the cutter body are usually separated when the cutter is selected, and it is generally used to process flat workpieces.

4. Thread milling cutter

The manufacturing material of the thread milling cutter is cemented carbide, the line speed is 80m/min, and the line speed of the high-speed steel tap is 10×30m/min, so the milling cutter is suitable for high-speed cutting.
