Forecast and analysis of carbide cutting tools market prospect
With the rise of global raw materials and the increasing number of global competitors, creating value for customers with high-quality products and excellent services has become the key to the competition. Therefore, knife manufacturers are actively seeking a better way for their own development and the progress of the whole industry.
It can be seen from the distribution map of the world's major tool materials, among which high-speed steel accounts for 35% and cemented carbide accounts for 15%.
Tungsten is now produced mainly in the Alps, the Himalayas and the Pacific rim.
China has a 60% tungsten deposit, and due to the shortage of raw materials in the international market, APT prices have risen from $50 per ton to around $250 per ton in recent years.
The cost increase will eventually be passed on to the end user of the tool.
At present, relevant research institutions in the world are actively studying this kind of situation. The main research scheme is to reduce the consumption of tungsten in the cutting tools as much as possible. The main method is to use tungsten only in the key parts of the cutting tools or to design special geometric parameters of the cutting tools.
It can be seen from the statistics of the cutting tool industry that the ratio of cemented carbide will gradually increase in the future, while the ratio of high-speed steel products will gradually decrease.
Statistics from the Japan tool association show that China has become the world's largest machine tool consumer, followed by Japan, the United States, Italy and so on.
Asia's economy is growing fast, with China's GDP growing by about 10% in 2007 and India's by about 8%, according to the Asian development bank.
Metal processing industry in a good economic environment, Japan also sustained high growth in recent years, from the point of cutting tool production, production of carbide cutting tools in recent years continue to grow, showed a trend of decline the start of HSS cutting tools, carbide were significantly increase in exports, the main export to Asia, followed by Europe, then in North America and other regions.
High - speed machining has been widely regarded as a technology to increase output and reduce manufacturing costs.
The concept of dry machining or trace lubrication is the main goal of the processing industry to reduce environmental protection and production costs.
For tool manufacturers and coating suppliers, the most important thing is productivity.
Cutting performance (cutting speed, cutting amount per unit time) increased by 20%, manufacturing cost reduced by 15%.
More and more stringent processing requirements require further development of tool materials and coatings to improve processing conditions and tool design.
The current challenges and areas to be improved mainly include: mechanical and structural characteristics: hardness, strength, wear resistance;
Thermal and chemical properties: heat resistance, insulation, catalysis;
Biological characteristics: adaptability, insecticidal characteristics;
Electronic and optical properties: reflectivity, transparency, etc.
In recent years, coated cemented carbide cutters have dominated the high performance cutters market.
The high demand in some special applications has promoted the development of special coatings or precision coatings.
What's the history of alloys?
The first people in the world to make alloys were the babylonians,
who began refining bronze (an alloy of copper and tin) 6,000 years ago.
China is also one of the earliest countries in the world to study and produce alloys.
The bronze (copper-tin alloy) technology was very developed in the shang dynasty (more than 3,000 years ago).
Around the 6th century BC (late spring and autumn period) the sword.
