Flat/Ball Nose 1/8 Inch, 1/4 Inch, 6mm, 8mm Tungsten Carbide End Mill For Iron Steel

The main features are as follows:
a. It can withstand high temperature, and can still maintain good cutting performance at about 800-1000 ℃. It can choose a cutting speed 4-8 times higher than high-speed steel when cutting.
b. High hardness at normal temperature and good wear resistance.
c. The bending strength is low, the impact toughness is poor, and the blade is not easy to sharpen.
Commonly used cemented carbide can generally be divided into three categories:
① Tungsten-cobalt cemented carbide (YG)
Commonly used grades YG3, YG6, YG8, where the numbers indicate the percentage of cobalt content, the more cobalt content, the better the toughness, the more resistant to impact and vibration, but will reduce the hardness and wear resistance. Therefore, the alloy is suitable for cutting cast iron and non-ferrous metals, and can also be used for cutting high-impact blanks and hardened steel and stainless steel parts.
② Titanium cobalt carbide (YT)
Commonly used grades are YT5, YT15, YT30, the number indicates the percentage of titanium carbide. After the carbide contains titanium carbide, it can increase the bonding temperature of the steel, reduce the friction coefficient, and slightly improve the hardness and wear resistance, but reduce the bending strength and toughness, and make the properties brittle. Therefore, the Alloys are suitable for cutting steel parts.
③ General hard alloy
Add appropriate amounts of rare metal carbides, such as tantalum carbide and niobium carbide, to the above two cemented carbides to refine their grains and improve their normal-temperature hardness and high-temperature hardness, wear resistance, bonding temperature and oxidation resistance , Can increase the toughness of the alloy, therefore, this kind of cemented carbide knife has better comprehensive cutting performance and versatility, its grades are: YW1, YW2 and YA6, etc., because its price is more expensive, mainly used for difficult Processing materials, such as high-strength steel, heat-resistant steel, stainless steel, etc.

Joint carbide co.,ltd was established on January 21, 2019, as a sales branch established by Zigong joint carbide co.,ltd in Chengdu.Our company covers 20,000 square meters was a high-tech enterprise integrating research, development, production and sales of cemented carbide products and cemented carbide rotary burrs，carbide tire studs，carbide repair tire stud，carbide particles & composite welding rods.

The company is committed to providing high-precision, high-speed and efficient metal grinding solutions and services for the machinery manufacturing industry. The company introduced the most advanced international five-axis five-linkage CNC tool grinder, three-coordinate tool detector and other equipment from Germany. The aim is to produce high-quality, internationally competitive products using internationally advanced equipment. At present, our company has become the largest rotary file production base in the country, with a mature R&D team and management team in China, and a stable supply chain.

As a metal cutting tool, the rotary file has been exported to Europe, North America, South America and a small number of Southeast Asian countries.A few days ago, the company has completed the accumulation of various infrastructure and technology research and development. Since 2020, our company has added 200 five-axis and five-linkage rotary grinders. By 2023, our company will invest a total of 400 five-axis and five-linkage rotary grinders. Grinding machine (total value 150 million yuan). By then, our company will become the world's largest supply base for rotary files.We have the world's advanced raw material cemented carbide formula technology, the most optimized advanced manufacturing process, and the largest-scale production equipment.
