Introduction
In recent years, China has actively advanced the standardization of the hard alloy industry in accordance with the overall principle of strengthening the work of industry standardization and promoting the transformation of industrial structure and quality. China National Development and Reform Commission has approved the implementation of a number of hard alloy industry standards, in accordance with the requirements of the industry and the progress of science and technology, to continuously enhance the safety, reliability, and high-end level of hard alloy products in China.
Safety and Reliability of Hard Alloy
Many hard alloy standards are in line with international standards but have higher requirements for safety and reliability. For example, the GB/T 16451-2009 Hard Alloy Organization Standard stipulates that according to the product structure and different properties, the hard alloy material should be divided into several grades according to the index. At the same time, the process parameters should be clearly defined, and the selection index system should be established, which should conform to the corresponding mechanical properties and chemical components of the material itself. GB/T 16450-2009 Hard Alloy Production Process Control Standard stipulates the requirements and rules of hard alloy production process control, including cutting blank size, cutting speed, cutting tools, surface roughness, etc. In addition, machining accuracy, grinding accuracy, cutting depth of processing allowance, etc. shall also be strictly controlled to ensure the safety and reliability of the product.
Quality of Hard Alloy
The standardization of hard alloy products also focuses on the improvement of quality. For example, GB/T 16452-2009 Hard Alloy Cutting Tool Performance Test Method Standard stipulates the requirements, conditions and methods for testing the performance of hard alloy cutting tools, including cutting chip form test, cutting surface finish test, cutting force test, tool life test, etc. The standard thus sets specific requirements for the machining quality of hard alloy products. Besides, GB/T 16454-2009 Hard Alloy Reamers Test Reproducibility Standard stipulates the method to reproduce the reaming test, so as to describe the technical conditions and parameters of reaming process and ensure the reproducibility of the whole process, so as to control the quality characteristic value of reaming.
Conclusion
In a nutshell, the standards of the hard alloy industry play an important role in ensuring the safety and reliability of hard alloy products and ensuring the quality of products. China National Development and Reform Commission has approved the implementation of a number of hard alloy industry standards, which are designed to continuously improve the safety, reliability, and high-end level of hard alloy products in China. By relying on the comprehensive standards, the hard alloy industry in China can achieve higher and higher growth, achieving greater development and progress.
