[0002] As an important cutting tool, spherical tooth cutter is characterized by large tooth pitch and fast cutting speed, so it is suitable for processing workpieces with higher hardness. Common types of spherical tooth cutters include hobs, gear shaving cutters, bevel gear processing tools, etc. Spherical tooth cutters are widely used in the field of mechanical processing, and spherical tooth cutters are mainly used in high-efficiency cutting occasions. However, traditional tooth cutters have problems such as excessive cutting temperature, easy wear, and cumbersome replacement and maintenance during the processing process, which cannot meet the needs of modern high-precision processing. Therefore, it is of great practical significance to develop a new type of spherical tooth cutter to solve existing problems and reduce production costs. Utility Model Content

The air cooling spray holes are connected to the air cooling pipe, and the air cooling pipe outputs the air cooling to the air outlet groove, and the air outlet groove sprays the air cooling to the scalloped cutter body, and then circulates with the outside air through the heat dissipation outlet, thereby effectively reducing the high temperature generated by the scalloped cutter during high-speed cutting. Since the temperature of the cutter is effectively controlled, the cooling and waiting time is reduced, the processing speed is increased, and the overall production efficiency is improved. Compared with cutting fluid cooling, cold air reduces the use of harmful chemicals and is more environmentally friendly. At the same time, since the consumption of cutting fluid and the frequency of tool replacement are reduced, the production cost can be reduced in the long run.

Unlike traditional spherical tooth knives, there is no need to send the entire tool back to the manufacturer for repair or directly discard it, thus saving time and transportation costs, greatly reducing maintenance costs and improving economic benefits. At the same time, using fresh and sharp knife particles can ensure the smoothness and accuracy of the cutting surface, reduce vibration and noise during processing, and thus improve the final quality of the product.

[0012] The utility model outputs air cooling to the air outlet groove through the air cooling pipe, and the air outlet groove sprays the air cooling to the scalloped cutter body, and then circulates with the outside air through the heat dissipation outlet, thereby effectively reducing the high temperature generated by the scalloped cutter during high-speed cutting. Since the temperature of the cutter is effectively controlled, the cooling and waiting time is reduced, the processing speed is increased, and the overall production efficiency is improved. Compared with cutting fluid cooling, cold air reduces the use of harmful chemicals and is more environmentally friendly. At the same time, since the consumption of cutting fluid and the frequency of tool replacement are reduced, the production cost can be reduced in the long run.
