Carbide teeth is a commonly used cutting tool, often used in machining.The following are some characteristic&application of carbide teeth:
Features:
High hardness: Carbide teeth are composed of hard particles such as tungsten carbide and bonding phases such as metal cobalt or nickel, and have extremely high hardness. This enables them to maintain good cutting performance under high speed cutting and heavy duty working conditions.
Wear resistance: The hardness of the carbide coal button makes it have excellent wear resistance, which can resist wear and corrosion during the cutting process and prolong the service life of the tool.
Impact resistance: Although cemented carbide is very hard, through appropriate alloy formula and special structural design, cemented carbide coal button can have certain impact resistance and can withstand shock and vibration during cutting.
Application:
Metal processing: Carbide coal teeth are widely used in the field of metal processing, including turning, milling, drilling, planing and other processes. They can be used to process various metal materials, such as steel, cast iron, aluminum alloy, etc.
Woodworking: Carbide coal buttons are also commonly used in woodworking, such as wood cutting, grooving and carving.
Plastic processing: Due to the good wear resistance and cutting performance of cemented carbide coal buttons, they are also used in plastic processing, such as injection molding, extrusion molding, etc.
Stone processing: Some tungsten carbide button for coal mining are also suitable for cutting and carving stone, and are used in the field of stone processing.
Tungsten carbide teeth are the main tools used for coal falling and crushing in coal mining machinery such as roadheaders. During the excavation process, due to the harsh working environment and the impact and friction of coal and rocks when the picks are working Therefore, the picks are required to have high corrosion resistance, wear resistance and hardness. In order to improve the service life of the picks, the current coal button are generally made of hard alloy teeth.
The wear and impact resistance of carbide picks is mainly due to their special material and design features:
Cemented carbide material: Cemented carbide is a composite material composed of hard particles such as tungsten carbide and a binder phase such as metal cobalt or nickel. This material has extremely high hardness and wear resistance, allowing carbide picks to maintain cutting performance for a long time in high friction and wear environments.
High Strength and Toughness: Carbide picks are designed with the right balance of strength and toughness in mind. Although cemented carbide is very hard, it is often combined with other metals or alloys to increase overall strength and impact resistance. This design makes the pick resistant to fracture and breakage when faced with impact or heavy loads.
Special tooth shape design: Carbide picks usually adopt special tooth shape design, such as cutting edge and blade shape. These designs can provide better cutting effect and wear resistance. The tooth surface of the pick has high hardness, which can resist wear and cutting force, while the shape of the cutting edge can reduce the friction and impact between the pick and the workpiece.
Surface treatment and coating: In order to further improve the wear resistance and impact resistance of cemented carbide picks, special treatment or coating is often carried out on the surface. For example, the surface hardness and wear resistance of picks can be increased by heat treatment, case hardening or the use of wear-resistant coatings, while providing better impact resistance.
The reason why cemented carbide buttons for coal mining are wear-resistant and impact-resistant is that the cemented carbide material has high hardness and wear resistance. At the same time, the overall wear resistance is improved through design optimization, balance of strength and toughness, and surface treatment. performance and impact resistance.
