The HRC value is a crucial indicator for measuring the ability of a cutting tool material to resist plastic deformation and indentation at room temperature. It directly affects the wear resistance of the tool and the degree to which the cutting edge remains sharp.

In the context of the rapid development of modern manufacturing, numerical control (NC) machining has become a core link in precision manufacturing. As the "teeth" in the processing procedure, the performance of NC tools directly determines the processing efficiency and the quality of the finished products. Among them, the red hardness of the tool material - the ability to maintain hardness, wear resistance and strength at high temperatures - has increasingly become a key factor influencing the quality of high-load processing.

The cutting processing of stainless steel is full of challenges due to its unique material properties. To achieve efficient processing and good surface quality, the key lies in choosing appropriate cutting tools and countermeasures based on its "difficult-to-machine" characteristics.

In modern industrial automation lines, whether it is precise electronic assembly or heavy material handling, a seemingly simple yet crucial actuating component is ubiquitous - it is the cylinder. As the core component that converts the power of compressed air into precise mechanical movements, the cylinder, with its outstanding reliability, extremely high economy, and flexible application, constitutes the muscles and skeleton of automated production, driving the assembly lines to operate efficiently and stably.

The Chinese hard alloy industry is undergoing a structural transformation driven by demand. The rapid development of new materials and high-end manufacturing has prompted raw material enterprises to accelerate their expansion and transformation. "The teeth of industry" is the industry's metaphor for hard alloys. As a key material with tungsten carbide as its main component, it is an indispensable strategic resource in high-tech fields such as aerospace, national defense, and precision manufacturing.

China's advanced manufacturing clusters are now presenting a pattern of gradient development, distinctive features and complementary advantages. Since 2019, the Ministry of Industry and Information Technology has been deeply implementing the special action for the development of advanced manufacturing clusters. Currently, 80 national advanced manufacturing clusters have been laid out and built across 26 provincial administrative regions.
