Honing is a kind of low-speed grinding process. It mainly uses a honing head equipped with honing stones to perform rotational and reciprocating movements on the inner surface of the workpiece, removing a small amount of material through the cutting action of abrasive grains. Compared with traditional internal cylindrical grinding, the honing process features low cutting speed, low cutting temperature, and uniform grinding pressure, which can effectively prevent surface burning and deformation.

In 2025, China's tungsten market bid farewell to its relatively stable past. During this year, the prices of tungsten products rose by more than 220% within just 12 months, with many core varieties constantly setting new historical highs. From the perspective of the internal industrial chain, this round of price increase was a typical supply-driven model, initiated by the raw material end and advancing all the way, with the downstream consumption end passively accepting the increase.

Against the backdrop of the rapid development of the new energy and semiconductor industries, high-purity special graphite, with its excellent electrical and thermal conductivity, high-temperature corrosion resistance, and stable chemical properties, has become an indispensable material in key processes ranging from the growth of photovoltaic monocrystalline silicon to the manufacturing of silicon carbide semiconductors.

As two major industrial cities in China, South Zhuzhou and North Zhengzhou, Zhengzhou has become the center of the national and even global synthetic diamond industry. This is the result of the combined effects of its profound historical accumulation, systematic technological research and development, complete industrial chain support, and strong policy support.

With a processing accuracy of 10 nanometers, this equipment can complete the processing of nickel-titanium high-temperature alloys with just one click. The electrical discharge technology is breaking through the limits of traditional manufacturing and is quietly reshaping the manufacturing landscape in the aerospace and medical device industries.

In multiple major domestic industrial exhibitions in 2025, a number of cutting tool manufacturers showcased their new coated tools, which attracted significant attention in the industry. These products not only achieved a lifespan increase of more than twice, but also demonstrated the rapid development of domestic coating technology.
