Optimization Study on Rotational Speed and Cooling System of High-Speed Dental Handpieces

This study investigates the efficiency of cooling systems in high-speed dental handpieces under high rotational speeds. By comparing different spray hole structures, bearing materials, and airflow channel designs, results show that the optimized triple-spray cooling system can reduce head temperature by approximately 15%, significantly extend bearing life, and enhance operational stability. The findings provide new insights into structural optimization and thermal management for dental handpieces.
