HRC45/55/65 Ball Nose Tungsten Carbide End Mill ALTIN Coating For Stainless Steel

Basic requirements of materials for cutting parts of milling cutters
1) High hardness and wear resistance: At room temperature, the material of the cutting part must have sufficient hardness to cut into the workpiece; with high wear resistance, the tool will not wear and extend the service life.
2) Good heat resistance: The tool will generate a lot of heat during cutting, especially when the cutting speed is high, the temperature will be very high, therefore, the tool material should have good heat resistance, even at high temperature It can maintain high hardness and has the ability to continue cutting. This kind of high-temperature hardness is also called hot hardness or red hardness.
3) High strength and good toughness: During the cutting process, the tool must withstand a large impact force, so the tool material must have a high strength, otherwise it is easy to break and damage. Because the milling cutter is subject to impact and vibration, the milling cutter material should also have good toughness so that it is not easy to chip and crack.

Common materials for milling cutters
1) High-speed tool steel (referred to as high-speed steel, front steel, etc.) is divided into general-purpose and special-purpose high-speed steel.
It has the following characteristics:
a. The content of alloy elements tungsten, chromium, molybdenum and vanadium is high, and the quenching hardness can reach HRC62-70. At a high temperature of 600 ℃, it can still maintain a high hardness.
b. The cutting edge has good strength and toughness, strong vibration resistance, and can be used to manufacture cutting tools with average cutting speed. For machine tools with poor rigidity, high-speed steel milling cutters can still be used for smooth cutting.
c. The process performance is good. Forging, machining and sharpening are relatively easy. It is also possible to manufacture tools with more complicated shapes.
d. Compared with cemented carbide materials, it still has the disadvantages of lower hardness, poor red hardness and poor wear resistance.
2) Cemented carbide: It is made of metal carbide, tungsten carbide, titanium carbide and cobalt-based metal binder through powder metallurgy process.

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.
