AI Technical Summary

Technical Problem

The heat dissipation performance of the existing ceramic CBN grinding wheel diamond rollers for oil pump nozzles is insufficient, which results in heat not being dissipated in time, affecting the service life of the rollers and the grinding quality.

Method used

The device employs a structural design that includes heat-conducting pillars, annular heat dissipation fins, airflow guide blades, and an air collection shroud. Heat is conducted to the heat dissipation fins through the heat-conducting pillars, and the airflow generated by the airflow guide blades accelerates heat dissipation. Combined with ventilation holes and biomimetic airflow guide grooves, the airflow path is optimized to achieve efficient heat dissipation.

Benefits of technology

It effectively extends the service life of the rollers, ensures dressing accuracy and grinding quality, reduces operating noise, and provides a stable working environment.
