Not long ago, Yanji Town, Echeng District, Ezhou City was recognized as the “first town of Chinese diamond tools†by China Diamond Information Network.

A diamond cutter is a high-hardness cutting tool made by mixing and firing a synthetic diamond with various metal powders and then welding it to a steel base member.
Zhang Zhongming, who is over 60 years old, is honored as the "grandfather of the Yanji diamond tool industry."
In the 1980s, Zhang Zhongming operated stone in Yanji. Cutting knives requires tools, and Zhang Zhongming has established contacts with two diamond sawmills in Shanghai and Beijing. Later, he "stealed the master" mastered the basic production technology of the diamond saw blade, and then formed his own "single-handed effort" through the tackling, and started the first diamond tool factory in Yanji.
Because of the considerable profits of its tool factory, Zhang Zhongming has no technical secrecy awareness. By the early 1990s, there were hundreds of diamond tool companies in Yanji, which were booming.
But the good times are not long. Due to various reasons such as the failure of local supporting facilities and the poor security situation, coupled with the preferential policies of the coastal areas and the relaxed environment, a large number of Yansha owners have developed in Guangdong, Fujian and Shandong. By the year 2000, there were only 10 diamond tool companies left in the decline of Yanji.

How to support the former booming industry again? Echeng was so painful that he decided to start from optimizing the environment and attracting the returning owners.
Since 2003, they have laid a solid foundation: hardening the road surface of Yanji to Echeng and Huangshi; building green belts, street lamps, water pipes and power transmission substations of the Diamond Tool Industrial Park; introducing preferential policies to eliminate “three chaos†Establish "China Diamond Tool Inspection and Inspection Center" to provide a platform for product development, production, testing and use; establish a diamond productivity promotion center to demonstrate the feasibility of major investment projects of enterprises, and support enterprises to promote new products, new technologies and new Process.
In a survey, Ma Chengxue, secretary of the Echeng District Party Committee, learned that the diamond geological drill bit can only penetrate the granite rock layer less than 20 meters thick due to the quality, and the sales are affected. So I invited experts from China University of Geosciences to improve the process and formula of diamond geological drill bits, which can penetrate rock formations from 50 meters to 60 meters deep and become a marketable commodity.
A similar story has also occurred many times in the district of Echeng District, Zhong Zhiqing. The strong support of local party and government leaders, coupled with the continuous improvement of the soft and hard environment, has greatly increased the attractiveness of the industrial park, and a large number of diamond tools have returned, bringing back hundreds of millions of investment.

After the Yanji diamond tool industry is booming again, the Echeng people are full of crisis: if they don't quickly achieve the biggest and strongest, they may be surpassed at any time!
Echeng has taken a series of measures for this purpose: please come to first-class experts for technical training; cooperate with Ezhou University to organize diamond superhard materials, train professionals for enterprises; hold “Diamond Development Innovation Forum†and obtain international cutting-edge technology and information...
At present, there are more than 1,000 technicians in the Yanji diamond tool industry, and there are more than 30 authoritative experts who provide technical support.
Now, the technology research and development of Yanji Diamond Tool Enterprise has been transformed from experimental technology to theoretical and technical level, and has overcome a series of technical problems such as intelligent sintering machine, single crystal and powder catalyst.
Scientific and technological innovation has made the Yanji diamond tool industry form a core competitiveness, and the industrial chain is also increasingly perfect. The Matthew effect has emerged: more and more foreign companies have settled in Yanji, and the industrial park has a production line with complete categories and numerous specifications, forming an industrial cluster with supporting, related, and integrated.
Recently, the "Safety Requirements for Diamond Circular Saw Blades" formulated by Ezhou City has been approved by the National Abrasives Standardization Technical Committee. This is China's first safety standard for diamond circular saw blades. With technical standards, the Yanji diamond tool industry has a greater say in the industry.
Today's Yanji Town, diamond tool enterprises reach more than 1,200, employing more than 28,000 people, with an annual output value of more than 1 billion yuan, the products are sold at home and abroad, accounting for more than 60% of the domestic market.
