A milling cutter is an important cutting tool in machining.

A milling cutter is a type of metal cutting tool widely used in the machining field. Its main function is to remove material from the surface of the workpiece through the rotation of the cutting edge, in order to meet the requirements for machining dimensions and surface quality.

A milling cutter typically consists of a shank, a blade, and a head. The shank is the part that fixes the blade to the machine tool, usually made of hard alloy or high-speed steel, providing sufficient strength and rigidity. The blade is the part that directly participates in cutting during the milling process, usually made of hard alloy, with its shape and edge type determined by specific machining requirements. The head connects the shank and the blade, commonly in the form of threaded connections or tool clamping.

Milling cutters can be divided into vertical and horizontal types. A vertical milling cutter is used on a vertical milling machine, with the blade mounted on the shank and fixed to the spindle for cutting. Vertical milling cutters are suitable for flat milling, slot milling, and curved surface milling. A horizontal milling cutter is used on a horizontal milling machine, with the blade mounted on the tool holder, achieving cutting motion through the movement of the tool holder. Horizontal milling cutters are suitable for flat milling, slot milling, and three-dimensional profile milling.

The selection of milling cutters should be determined based on specific machining requirements. Generally, workpieces with higher hardness require hard alloy blades, while those with lower hardness can use high-speed steel blades. Additionally, workpieces with high precision requirements should choose milling cutters with good quality and high precision. At the same time, the cutting speed, feed rate, and cutting depth of the milling cutter should also be determined based on the workpiece material, tool material, and cutting conditions.

Milling cutters play an important role in machining. They can perform various shape processing operations, such as flat milling, slot milling, curved surface milling, and thread milling. By combining different forms of blades and milling cutters, complex parts can be processed. During the milling process, the milling cutter can control the quality and precision of the machined surface by adjusting the cutting speed, feed rate, and cutting depth.

In summary, milling cutters are an important cutting tool in machining, capable of performing various shape processing operations. By selecting the appropriate milling cutter and adjusting cutting parameters, the surface quality and precision of the workpiece can meet machining requirements. The application of milling cutters is extensive, significantly contributing to improving machining efficiency and reducing costs.
