Abstract:
As a key project of aero-engine, precision gear, 5G intelligence and other countries, high speed and ultra-high speed forming grinding technology, superhard material electroplated grinding wheel has become one of the indispensable tools.By the United States, Japan and other countries technology blockade, current in our country electroplating wheel start late, the technology of electroplating wheel is backward.The main reason is lack of professional precision shaping equipment, low manufacturing accuracy, which seriously restrict it’s industrial application.It is great guiding significance and strategic significance for promoting the industrialization of high-speed and ultra-high-speed forming grinding technology, improving the manufacturing accuracy of key parts of complex surface in aerospace, military and other industries, and ensuring the national security to overcome the precision shaping technology of complex surface of electroplating wheel and break through the technological blockade.In this paper, the dressing technology of superhard material products at home and abroad was reviewed, the contour characteristics and dressing mechanism of superhard material electroplated grinding wheels were analyzed, and the technical barriers existing in the precision shaping of complex profile of electroplated grinding wheels were revealed. By analyzing the relevant dressing equipment in the current industry, it is deduced that "hard dressing" is the reliable technological means to ensure the contour of grinding wheel at present. It is pointed out that the future dressing equipment should be customized, and focus on the development of special equipment from the precision tool setting technology, dressing interference CNC intervention technology, tool grinding wheel loss avoidance/quantitative compensation and other aspects. At the same time, it is pointed out that industrial laser ablation is one of the key research directions of superhard material dressing in the future.
