The gearbox is responsible for transmitting force, rotational motion and torque from the internal combustion engine or electric machine all the way to the wheels. It is a critical part of all vehicles because of its ability to move the vehicle in an energy-efficient manner.

Tessa Precision's solutions and tools for transmission parts are backed by in-depth application expertise. With a professional engineering team that supports the automotive industry with multiple quality solutions, we have a strong presence in the international market as well. Here we share selected high-productivity solutions to some of the challenging characteristics of transmission part production.

axis

These parts come in many different shapes and forms and their primary purpose is to transmit power.

Shaft parts come in many different shapes and forms, and their primary purpose is to transmit power.

Slender shafts require rigid clamping systems and light cutting tools to avoid vibration. When it comes to gears, careful preparation during the hardening phase is critical to success.

Hardening is preceded by soft turning and tooth milling, where the challenge is often achieving tight dimensional tolerances. Careful preparation for the hardening stage allows for a relatively straightforward hard part turning operation. In hard part turning, predictable machining and good surface quality are crucial. In addition to all this, high economy must be ensured.

gear

Gears also come in many different shapes and forms and are used to convert vehicle power into different RPMs and torques.

shift sleeve

The shift sleeve is one of the parts of the synchronizer assembly and is used in manual transmissions to connect/disconnect the main gear to the output shaft.

The main challenge in machining shift sleeves is often obtaining good machining security to achieve high productivity and tight tolerances. Grooving is a critical and challenging operation that requires a safe, efficient process and excellent chip control. In hard part turning, predictable machining and good surface quality are crucial. In addition to all this, high economy must be ensured.
