In the automotive and motorsport industries, optimizing friction surfaces in engines and transmission systems is crucial for reducing wear and tear. Smooth and isotropic surface structures not only minimize CO2 emissions but also extend the lifespan of components. As oils become increasingly diluted, there are higher demands placed on component surfaces. Even seemingly simple tasks like deburring or targeted rounding often require significant effort.Traditionally, post-processing has involved methods such as sanding, polishing, or chemical acceleration processes. These methods can be costly and time-consuming, and they often produce oriented surface structures rather than isotropic ones. In chemical acceleration treatments, chemicals like sodium chromate are used in vibratory bowls, which are classified as particularly concerning substances. The costs associated with the procurement, neutralization, and disposal of these chemicals further diminish the economic viability of post-processing.To leverage potential efficiencies, flow processing techniques can reduce friction losses during gear surface processing. This leads to improved efficiency and reduced CO2 emissions for end customers.

Steering Worm Applications

In vehicles, audible issues such as squeaking brakes, whining transmissions, and clutch vibrations can be mitigated through the use of proven flow finishing processes on steering components like worm gears. This approach compensates for irregularities that lead to higher side friction values.

Rotor Shaft Applications

For radial shaft high-speed seals, the interface between the sealing surface and lip requires stringent performance standards. In some cases, enhancing performance is necessary. Smoothing the running surfaces can extend the lifespan of sealing systems under high sliding speed loads.

Motor Applications

The so-called hairpin stator is commonly used in electric motors. Hairpins are made from copper wire coated with an insulating layer. During the automatic production and assembly of hairpins, careful handling is essential to protect the insulation from damage. Therefore, all components in the production system that come into contact with the wire must undergo meticulous deburring and polishing to achieve a high gloss finish.

Conclusion

By employing various sandblasting abrasives techniques, automotive manufacturers can effectively polish critical components. This not only enhances performance but also contributes to sustainability by reducing emissions and extending component lifespans. As the industry continues to evolve towards more efficient production methods, these advanced finishing techniques will play a pivotal role in meeting both performance standards and environmental regulations.
