Continuous generating gear grinding is characterized by the strict coupling of certain axis movements of the machine. The rotational velocities of workpiece ω 1 (C‐axis) and tool ω 0 (B‐axis) are synchronized in accordance to their teeth ratio so that the teeth of the workpiece (z 1) are immersed in a gear of the grinding worm (z 0), see Figure 1(A).
Gear grinding process is the method of finish grinding gear teeth and is a significant step when building high precision gearing.Gears with precision ground teeth work more softly and consume more evenly than gears with cut teeth. Gear grinding process is often done as a step in the gear manufacturing method, and we also give a gear grind only service.
Quality of Finish Hobbing. One would expect such a quality level as a result of a second gear finishing operation after hobbing, like honing, rolling or gear grinding. Gear grinding has legitimate reasons to be used post-gear hobbing to eliminate heat treatment distortion and have higher surface finish. In statistical terms, the hobbing process ...
