What is gear hob?
The gear hob is a tool for processing straight and helical cylindrical gears according to the principle of helical gear meshing. This tool has high machining accuracy, high production efficiency, and a wide range of applications.
How gear hobs work?
During processing, the hob is equivalent to a helical gear with a large helix angle, and the number of teeth is the number of heads of the hob. The workpiece is equivalent to another helical gear, which meshes with each other according to a pair of helical gears and rotates at a fixed speed ratio. , The tooth profile of the gear is enveloped by the tooth profiles of the adjacent positions of the sequential cutting. Most of the commonly used hobs are single-headed (see thread). In mass production, multi-headed hobs are often used in order to improve efficiency.
CBN grinding wheel for gear hob cutter sharpening
Gear hob cutter is an important component in various mechanical rotation systems, so the surface finish and dimensional accuracy of gear hob cutter have high requirements. The choice of grinding wheel will also affect the service life of gear hob, and the hardness, wear resistance, high temperature stability, high temperature stability and thermal friction coefficient of grinding wheel directly affect the precision of hob grinding.

In modern manufacturing, tungsten steel (hard alloy) is widely used due to its high hardness and wear resistance. However, the requirements for tools when processing tungsten steel are extremely high, especially the selection of suitable grinding wheels is crucial in the grinding process. This article will share the case of us providing customers with high-quality grinding wheels and successfully solving their processing problems.
SG grinding wheels are suitable for grinding carburized steel. Their high hardness and self-sharpening properties enable them to effectively grind the high hardness surface of carburized steel, while low heat generation and good heat dissipation reduce thermal damage during the grinding process. In addition, the wear resistance of SG grinding wheels also helps to extend the service life of the grinding wheels and reduce grinding costs.
