Gear Shaving

                                                          
Gear shaving machine is a solution used in the finishing operation of an external spur and helicalgear. It is also possible to shave an internal gear, although generally the work conditions are less favorable. The shaving process can improve the quality and precision of a hobbed gear of 3 classes. However, the final resultsdepend not only on the accuracy with which the shaving cutter and the gear shaving machine is designed and manufactured, but also on the quality achieved  with the prior machining.

Gear shaving is still today the most widely usedmethod for the finishing of gear teeth, especially for the continuous productionof large lots, since it represents the best cost/performance ratio. The main limit of the gear shaving process is the lack of the chance to removethe distortion caused by heat treatment. Usually, when high noiselessnessand strict quality levels are strictly required, the grinding operation is the best solution, although obviously more expensive.
In the automotive industry, the vast majority of gears used in gearboxes are suitable for gear shaving. The productivity of a gear shaving machine is much higher compared to a gear grinding machine. The gear shaving operation is composed by the simultaneous rotation of workpiece and cutter as a pair of gears with crossed axes. The crossed axes generate a reciprocalsliding action between the flank, gear tooth and the cutter teeth. Gear shaving should becarried out using extremely precise gear shaving machines andtools. That is why it is essential to rely oncompanies with broad and proven understanding of gear technology with a particular focus on innovation and development, so that they can offer the best cost effective solution on the market for your specific needs.
