Gear honing is a continuous precision machining process in which the honing tool and the workpiece roll off one another. In the machining zone, a sliding movement running diagonally from the tip to the root of the tooth results from the angle of intersection between the axis of the workpiece and the axis of the tool. The surface structure this generates on the flank is typical of this microcutting process. Gear honing as the final machining step in making gears is now an established machining step with all renowned gear and automotive manufacturers.
The primary objective of gear honing is to reduce noise in the transmission by changing the surface structure of tooth flanks.
Other improvements are:
- Reduced roughness
- Increased strength
- Improved concentricity
- Elimination of damage
- Correction of distortion due to the hardening process
- Extended workpiece life
