Our high-grade diamond break the foreign monopoly
Manufacturer of diamond tools are numerous, but the backward production technology, can only produce low-grade tools. Research and development of high-grade diamond tools has become essential. To this end, the Ministry of Science and Technology Department of Guangxi issued a development of laser welding thin diamond drill bits, diamond wire saw, diamond grinding of glass processing research tasks.
Technology and innovation as the key point:
1, the establishment of "equivalent cutting edge" and "eat-in depth" two mathematical models.
2, the establishment of artificial diamond impregnated tools to predict the performance appraisal evaluation system.
3, the development of multi-layer technology, a number of floating rope saw assembly manufacturing technology. To fill the domestic production Φ8 sintered diamond wire saw blank.
4, the development of positive displacement drilling despise pressure, such as laser welding drill bit technology. Multi-station, single tooth, continuous teeth tooling design and other location in the country with originality.
5, the development of high-grade diamond glass grinding wheel manufacturing technology.
6, the successful use of domestic high-strength synthetic diamond granularity preparation of high-grade cutting tools.
The project developed by the rope saw, drill bit, glass milling round products such as technical and economic indicators rank the leading domestic level, including production technology and integrated indicators Wire Saw products reach the international advanced level, laser welding of thin-walled diamond drills bonding strength between diamond teeth and the steel body is more than the German standard (DEA). Products have been widely used in the country and enter the international market, it has obvious economic and social benefits.
Implementation of the project to solve China-made satellites with high-strength high-grade diamond manufacturing diamond tools major technical problems, formed with independent intellectual property rights of high-grade diamond products, has been formed wire sawing, grinding, laser welding tools three industrial production lines. The cumulative output value of 50 million yuan, profits and taxes more than 1050 million, earning more than $ 500,000. Breaking the high-grade diamond tools for the professional market monopoly international American and European countries, will promote China's diamond production from the power to a power forward.
