At the 26th International Conference and Exhibition of the European Society for Precision Engineering and Nanotechnology (euspen) held in Kraków, Poland, Mr. Zhanjie Zhang, a PhD student from Professor Jiong Zhang’s Smart and Precision Finishing lab at Department of Mechanical Engineering (MNE) of CityUHK, was awarded the prestigious Heidenhain Scholarship. Sponsored by the precision measurement leader HEIDENHAIN, this award is granted to 10 student researchers globally each year in recognition of their strong academic accomplishment and significant potential in the field of precision engineering.
In his paper, "Magnetically driven internal finishing of stainless steel tubes by a novel electrostatic flocking and drum-shaped polishing tool," Mr. Zhang introduced a flexible polishing approach aimed at achieving nanometer-level surface precision for tubular components. These components are widely used in high-tech industries such as aerospace, semiconductor fabrication, and biomedical engineering, where smooth internal walls are critical for system reliability. Experimental results demonstrated that this method improves the internal surface quality of industrial tubes by over 89% within 10 minutes, while maintaining excellent processing repeatability.
This achievement reflects the research capabilities of the Smart and Precision Finishing lab at MNE of CityUHK in advanced ultra-precision finishing. The study was conducted under the dedicated guidance of Professor Jiong Zhang and supported by the CityUHK Start-up Fund and the National Natural Science Foundation of China (NSFC).
