Existing Barrel Finishing and Ultrasonic Barrel Finishing (1) 2024/5/2
Barrel finishing, widely used in industry, is an old traditional process in which a workpiece and abrasive (called media) are placed in a drum-shaped container, and then an auxiliary agent (compound) is added, followed by water, and the container is rotated or vibrated to polish the surface. The workpiece and abrasive stones rub against each other to polish the product surface.
The workpiece and abrasive (media) must be separated, and since the workpiece is contaminated with abrasives and compounds, water-based cleaning is required after barrel polishing. Of course, wastewater treatment must also be considered. The above processes are a major obstacle to automation in mass production plants for precision parts. In general, because of the heavy workload, young human resources cannot be recruited, and the reality is that male workers over 60 years old, who have few job opportunities, and foreigners are being asked to perform this work.
Ultrasonic barrel finishing is the exact opposite. No media is used. The workpieces are placed in a hexagonal rotating cage, and the cage is rotated in water to simultaneously deburr, polish, and clean the workpieces using ultra-powerful ultrasonic waves. Automatic drying is easy, if necessary. Light work. Even a woman can do it. No need to worry about wastewater treatment. Faster polishing time than existing barrel finishing. This is because deburring, polishing, and cleaning are performed by the synergistic effects of the co-abrasive vibration effect of more than 20,000 times per second and the positive and negative shock waves of huge numerous vacuum energy balls – cavities (micro vacuum nuclei) with a maximum diameter of 10mm generated by ultrasonic waves.
As ultrasonic barrel finishing is commercialized and spread around the world, which is your choice: to continue with your existing barrel finishing process or to introduce ultrasonic polishing in order to strengthen your global competitiveness through increased automation, reduced labor costs, and consistent quality?
