China’s diamond saw blade industry launches “US Breakthrough Battle.”

As Chinese enterprises become increasingly integrated into the global economic stage, various economic frictions and disputes among nations have also been on the rise. Although the U.S. Diamond Saw Blade Manufacturers Association has submitted an anti-dumping petition to the U.S. government targeting diamond circular saws and components from China and South Korea, the petition remains unresolved. Nevertheless, intermediary organizations such as the Shanghai Stone Industry Association promptly mobilized dozens of Chinese enterprises from Jiangsu, Zhejiang, and Shanghai to join forces and collectively respond to the pressure from the U.S. anti-dumping investigation.

It has become an inevitable trend in China for tool-grinding machines to replace manual tool grinding.

Speaking of the reasons behind the popularity of portable drill and milling cutter sharpeners, Zhao Changming offered this analogy: After humanity invented mechanical transportation, once we’ve got it, who would still bother walking or riding horses when traveling long distances? Similarly, once people get used to using drill and milling cutter sharpeners to grind their drills and milling cutters, who would still bother sharpening them by hand? How many companies could possibly refuse a machine that not only helps businesses cut production costs but also relieves bosses of the headache-inducing issue of personnel management?

Overview of the Alloy Saw Blade Industry

1. When the base material exhibits significant deformation, uneven thickness, and large tolerances in its internal bore—issues stemming from inherent defects in the base material—grinding errors will occur regardless of the type of equipment used. Large deformation of the base material causes deviations in the two-side angles; a large internal bore in the base material leads to deviations in the diameter runout; and uneven thickness of the base material results in deviations in both the back rake angle and the front cutting edge angle. If cumulative dimensional tolerances exceed acceptable limits, the quality and precision of the saw blade will be severely compromised.

Copper-based diamond circular saw blade manufacturing technology

Diamond circular saws are specialized tools designed for cutting non-metallic materials such as granite, marble, concrete, refractory materials, glass, ceramics, road surfaces, and graphite electrodes. They are renowned for their sharpness and wear resistance. Over the past decade, with the rapid development of China's construction materials industry, domestic demand for diamond circular saw blades in the stone processing sector has surged rapidly. The key technology in manufacturing diamond circular saw blades lies in the chemical composition of the saw teeth and the corresponding preparation processes.
