The Conference will be held from 21st-23rd October 2023 in Hong Kong, China.

The CHINA-JAPAN International Conference on Ultra-Precision Machining Process (CJUMP) 2023


The CHINA-JAPAN International Conference on Ultra-Precision Machining Process (CJUMP) was initiated in 1984. The CJUMP2023 will be held in China, during 21st-23rd October 2023. The goal of the conference is to bring together researchers and academics from China and Japan to discuss novel theories, technologies and applications in the areas of precision engineering, micro engineering and nano-technology. In order to adapt the new situation of ultra-precision machining and surface finishing technology, this Conference will cover new developments for process technology on machine tool, instruments and metrology in precision measurement, micro and nano-machining.

It is our pleasures that all participants will enjoy this Conference, that they get an overview about the current trends and acquire new ideas for solving their current tasks and problems. In addition, this conference will be an ideal opportunity to meet colleagues or friends from the field of Ultra-precision machining and related topics. We are looking forward to meeting you in Hong Kong.
