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.
