On May 13-14, the National Natural Science Foundation of China, organized by the National Natural Science Foundation of China, was selected by the Key Laboratory of Special Equipment Manufacturing and Advanced Processing Technology. Wang Guozhen, Director of Engineering Science Division II of the Department of Engineering and Materials Science of the National Natural Science Foundation of China, Lu Wenge, Director of the Natural Science Foundation of Zhejiang Province, and Ma Yu'an, Vice President of the University attended the acceptance meeting. More than 50 experts and scholars from relevant institutions attended the meeting. The "Basic Research on Advanced Ceramic Precision Efficient Processing Technology" hosted by Professor Yuan Julong, the deputy director of the key laboratory, passed the acceptance test at the meeting. During the meeting, Zhang Lipin, President of the School and Director of the Key Laboratory, met with the leaders of the National Natural Science Foundation of China and related experts.
The "Basic Research on Advanced Ceramic Precision Efficient Processing Technology" hosted by Yuan Julong is the first key project of the Mechanical Science Department of the National Natural Science Foundation of China for Engineering and Materials Science, which is independently undertaken by non-"211" universities. During the meeting, the acceptance expert team composed of 7 experts of the Chinese Academy of Sciences Ren Luquan and the Chinese Academy of Engineering Academician Tan Jianrong as the deputy leader gave a high evaluation of the project. The comprehensive evaluation was excellent, which marked my laboratory. The basic research field of advanced ceramic precision and efficient processing technology has entered the domestic leading ranks.
The project fully completed the plan and made outstanding progress. It proposed a new method of semi-fixed abrasive grain processing and semi-fixed abrasive design technology with low bond strength and weak plastic deformation, revealing the advanced ceramic materials in the brittle and plastic domains respectively. The processing rule of uniform removal of elastic domain; the semi-fixed abrasive tool with low bond strength and weak plastic deformation property was developed, and its performance detection and evaluation system was established. The spherical full-envelope grinding of eccentric grinding and double-rotation grinding was proposed. The ball principle provides a theoretical basis for solving the technical problems of low ball precision and low ball formation efficiency. The quantitative analysis method of spherical grinding uniformity is established, which provides an effective prediction method for the optimization of the ball processing process; The ball ball processing technology expert database and the ball fixed abrasive grinding technology, chemical mechanical polishing technology, grinding disc in-place trimming and other ceramic ball precision efficient processing key technology, formed a new method of ceramic ball precision high-efficiency batch processing technology; successfully developed based on all-inclusive A new type of precision ball grinding machine that grinds into a ball, realizes Tao Ball bulk efficient processing. During the project research period, the project team published 58 academic papers, including more than 80 articles by SCI and EI; 4 special invited reports at international conferences; 1 second prize of National Science and Technology Progress Award, provincial and ministerial level 1 1 prize, 1 second prize, 1 third prize; 14 invention patents, 5 invention patents and 5 software copyrights; extensive international academic exchanges and training of a group of doctoral students master.
During the meeting, the leaders of the National Fund Committee and related experts also visited key laboratories, and inspected the “Zhejiang University of Technology Ultra-precision Machining Research Center” and the “Key Laboratory of Special Precision Grinding Technology for Machinery Industry” where the project team is located. I highly appraised the research results and research conditions of my laboratory in the direction of ultra-precision machining technology and equipment research.
