Design features of carbide stick blades for bevel gears
Carbide stick blades for bevel gear machining typically have a hardness of 89 - 94 HRA (Rockwell A).
Since the teeth of bevel gears are involute conical, the shape of the cutting edges of the carbide stick blades needs to be precisely matched to the tooth profile of the bevel gears. The tooth profile of the blade is usually determined by complex mathematical calculations and computer-aided design (CAD). For example, for bevel gears of different modules, the tooth thickness, tooth height and tooth profile of the tool have to be adjusted accordingly to ensure that the bevel gear teeth can be precisely cut to meet the design requirements during the machining process.
In order to adapt to the special requirements of bevel gear machining, the carbide stick blades angle of the carbide tool has its own unique design. The front angle is typically between 5° - 15°, which reduces cutting forces and makes it easier for the tool to cut into the bevel gear material. The back angle is typically between 8° - 12° and is designed to minimize friction between the back face of the tool and the machined surface. The camber angle, usually between - 5° and + 5°, facilitates chip guidance and prevents chip buildup that can affect machining quality.Optimization of these cutting edge angles helps to improve the cutting efficiency and machining quality of the tool.
