北京市电加工研究所曹凤国、孙琏妮、王燕春、李小兵等同志研究的《聚晶金刚石工具电火花加工技术》,以独特新颖的构思,显著的经济效益,1984年被评为国家发明二等奖。今年经中国发明协会推荐参加日内瓦第十三届世界新发明展览又获银奖(图1)。日内瓦世界新发明展览由瑞士联邦政府和世界知识产权组织(WIPO)支持和赞助下召开。它是参展国多、规模大、影响也较大的国际性发明展览之一。《聚晶金刚石工具电火花加工技术》能在这样的展览会上获奖,说明我国超硬材料工具制造技术飞速发展,并正走向世界。
The “Polycrystalline Diamond Tools EDM Technology” researched by the Beijing Electric Process Institute Cao Fengguo, Sun Xiaoni, Wang Yanchun, Li Xiaobing and other comrades, was uniquely conceived with remarkable economic benefits. In 1984, it was awarded the second national invention. prize. This year, it was also recommended by the Chinese Association of Inventions to participate in the 13th World New Invention Exhibition in Geneva and won the Silver Award (Figure 1). The Geneva New World Exhibition was held with the support and sponsorship of the Swiss Federal Government and the World Intellectual Property Organization (WIPO). It is one of the international invention exhibitions with many exhibitors, large scale, and large influence. “Polycrystalline diamond tool EDM technology” can be awarded at such an exhibition, indicating that China’s superhard material tool manufacturing technology is developing rapidly and is moving toward the world.
