Coarse milling cutter, also known as wave edge milling cutter, is a kind of milling cutter with special cutting edge. Its cutting edge part shows a continuous waveform, making it in the machining process can be better adapted to the characteristics of the processed material, thus improving cutting efficiency, reducing cutting force, but also to a certain extent to improve the machining accuracy and surface quality.

The manufacturing process of wave edge milling cutter mainly includes the selection of tool material, heat treatment, cutting edge processing and surface treatment and other steps. The selection of tool material is the key to manufacturing wave edge milling cutter, usually choose high hardness, high wear-resistant materials, such as cemented carbide, ceramics and so on. During the machining of the cutting edge, precision grinding technology is required to ensure the shape and accuracy of the cutting edge. Finally, surface treatment is needed to improve the corrosion and wear resistance of the tool.

Wave edge milling cutters are suitable for a variety of different machining areas, especially in the machining of difficult-to-machine materials with excellent performance. For example, in the aerospace field, wave edge milling cutters are often used for processing high-strength, high hardness composite materials; in the automobile manufacturing industry, wave edge milling cutters are widely used in the processing of engines, transmissions and other components; in addition, in the mold, gears, quenched steel and other processing areas, wave edge milling cutters have also been widely used.

Compared with the traditional milling cutter, wave edge milling cutter has the following advantages and characteristics:

1. High cutting efficiency: due to the unique shape of the cutting edge of the wave edge milling cutter, it can be better adapted to the characteristics of the processed material, thus improving the cutting efficiency.

2. Small cutting force: the cutting edge of wave edge milling cutter is continuous and shows wave shape, which can effectively disperse the cutting force during the cutting process and reduce the force on the tool and workpiece.

3. High machining accuracy: due to the high precision of the cutting edge of the wave edge milling cutter, it can ensure that the machined workpiece has high dimensional accuracy and surface quality.

4. Strong adaptability: Wave edge milling cutters are suitable for machining various hardnesses and materials, especially in the machining of difficult-to-machine materials with excellent performance.

5. Long service life: Due to the strict material selection and exquisite manufacturing technology, the service life of wave edge milling cutters is longer than that of traditional milling cutters.
