From September 26 to 28, 2025, the 23rd China Conference on Abrasive Technology (CCAT 2025) was successfully held at Huaqiao University in Xiamen. Organized by the Abrasive Technology Sub-Committee of the Production Engineering Branch of the Chinese Mechanical Engineering Society, and hosted by Huaqiao University and the National Key Laboratory of High-Performance Tools, this conference focused on basic theoretical research, key technological breakthroughs and engineering application innovations in the field of abrasive technology, aiming to promote academic prosperity and technological progress in this field.

The conference built a high-level academic exchange platform for domestic scholars in the abrasive technology field. Nearly 400 experts, scholars and industry elites from 112 universities, research institutes and 25 enterprises across the country gathered in Xiamen for in-depth exchanges. This effectively promoted in-depth cooperation among industry, academia and research sectors, as well as the cultivation of young scientific and technological talents. Participating experts and scholars conducted in-depth discussions on cutting-edge directions such as new principles, new processes and new equipment of abrasive processing, jointly explored new paths for industry development, and contributed wisdom to promoting the high-quality development of China's manufacturing industry.

For the first time, the conference established the Abrasive Technology Youth Working Group, and Associate Professor Wang Yan from the School of Mechanical Engineering of our university was selected as a member of this group.At the Young Scholars Forum, Associate Professor Wang Yan gave a special report titled "Research on Machinable Modification of Metal Surfaces by Ultrasonic-Assisted Nanosecond Laser and Analysis of Grinding Characteristics". He systematically introduced innovative achievements in machinable modification of metal material surfaces and precision grinding, which triggered enthusiastic discussions among participating experts on site.

By actively organizing and participating in such high-level academic activities, the School of Mechanical Engineering has further expanded its academic influence, strengthened scientific research cooperation with domestic peers, and injected new development momentum into improving the school's disciplinary construction level and enhancing its scientific research innovation capabilities.
