Gears are among the oldest man-made components in the world. The first and oldest gear applications were already found in ancient times.


Due to the higher accuracy, machining processes are the preferred method for the industrial production of gears. Nowadays, hard-fine machining with non-defined cutting edge is increasingly used to improve the surface structure. The method offers numerous advantages, especially in terms of geometry and surface quality, since the finished transmission’s power transfer is significantly increased. This directly increases efficiency, which is associated with a reduced energy loss.

Trends and innovations


In the automotive industry, a significant shift from manual transmissions to automatic transmissions can be noticed. In addition, the constant increase in e-mobility will also have a lasting impact on the transmission industry as a whole. We are constantly working on the further development of perfectly tailored processes for all steps in the machining of gearings.

The requirement profile


To achieve maximum performance, a transmission requires the optimum interaction of all components. The requirements for the machining of the individual components are correspondingly complex. Carriers, shaft components and the associated gearing all demand precise machining. Less noise, smoother running, long lifetime and optimised performance data play a key role when it comes to choosing the right tool.


Gear grinding consists of three processes: continuous and discontinuous roller and profile grinding as well as gear honing. Tyrolit offers system solutions for all processes involved in the hard finishing of gearings.
