Hobbing cutter is a cutting tool used for machining gears. Its working principle is to place the hobbing cutter on the gear and move it to roll and cut the tooth surface of the gear. Due to the high requirements of gear hobbing cutters, cubic boron nitride grinding wheels are required to ensure their machining accuracy and surface smoothness. Generally speaking, the selection of grinding wheel thickness depends on the material and geometric shape of the hobbing cutter. Usually, coarse grinding wheels are suitable for processing shear type materials, while fine grinding wheels are suitable for grinding materials. The selection of grinding wheel hardness should be based on the hardness of the grinding material. If the hardness of the grinding material is high, a grinding wheel with higher hardness should be used; If the grinding material is soft, a grinding wheel with lower hardness should be used. For high-speed steel gear hobbing cutters, it is recommended to use resin bonded cubic boron nitride sand wheels. The 4BT9 grinding wheel material has high hardness, strength, fast grinding speed, and does not cause excessive thermal deformation to the cutting tool. 4BT9 grinding wheel can not only improve machining quality and efficiency, but also extend the service life of gear hobbing cutters.
