Cemented Carbide Button Functions
- Cutting and Crushing: Their extreme hardness and wear resistance allow them to penetrate and break apart hard rock formations effectively.
- Drilling Efficiency: They are designed to withstand high impact forces and percussive drilling, enabling faster penetration rates and higher productivity.
- Wear Resistance: Made from a combination of tungsten carbide and a binder metal, they are highly resistant to abrasion, significantly extending the lifespan of the drill bit.
- Energy Transfer: The buttons transmit the percussive energy from the drilling machine to the rock, ensuring efficient and powerful drilling.
- Versatility: With various shapes like spherical, ballistic, and flat, they are engineered for different rock types and drilling applications, from soft formations to very hard and abrasive rock.
customize Your Cemented Carbide Button
Diameter (D): Customize diameter for specific rock types. Larger diameters offer more wear resistance for softer rock; smaller diameters provide higher penetration force for harder, denser formations.
Height (H): Adjust height to control durability. Taller buttons extend service life in abrasive conditions; shorter buttons are for applications needing minimal protrusion and maximum impact force.
Spherical Radius (SR): Optimize the radius for impact. A larger radius improves resistance to fracturing in hard rock. A smaller radius concentrates force for better penetration in less consolidated materials.
Angle α: Fine-tune angle α to control cutting aggression. A steeper angle is for softer rock, while a shallower angle is preferred for harder formations to improve wear resistance.
Angle β: Angle β controls the button’s stability within the bit body. A well-chosen angle ensures proper force transfer, preventing detachment under high drilling stresses.
Various Cemented Carbide Buttons
Spherical/Domed Buttons
Spherical buttons are characterized by a rounded, domed top. They are a universal choice due to their excellent toughness and high resistance to fracturing. This shape efficiently distributes impact force, making them ideal for drilling in extremely hard and abrasive rock formations and extending bit life.
Chisel (Conical) Buttons
Chisel or conical buttons feature a tapered, pointed tip. They are well-suited for medium-hard rock formations and are used in percussion and cone bits. This shape concentrates impact force for maximum penetration, enhancing drilling speed and efficiency in appropriate ground conditions.
Parabolic (Ballistic) Buttons
Parabolic buttons have a bullet-like shape, balancing fast penetration with good wear resistance. This design provides an aggressive cutting action for drilling in hard rock formations. They are a versatile choice, offering a compromise between the speed of conical types and the durability of spherical ones.
Flat Buttons
Flat top buttons have a cylindrical, flat surface. They are used in very soft, unconsolidated formations, such as clay or sand, where a scraping and cutting action is needed. Their broad surface also helps reduce wear on the steel body of the drill bit.
Wedged Buttons
Wedged buttons feature a sharp, angled cutting edge designed for high-speed drilling. They are particularly effective in soft rock formations with low abrasiveness. This specialized shape provides an efficient cutting action, making them suitable for specific types of submersible and cone bit applications.
Inserts (Tips) for Coal & Road-Cutters
These specialized inserts are engineered with a unique, dual-radius profile. They are designed for high-performance drilling in coal seams and road surface mining. This shape provides an effective cutting action while withstanding the specific challenges of these materials.
Spoon (Scoop) Buttons
Spoon or scoop buttons are characterized by a concave or spoon-like cutting face. They are specifically designed for roller bits and excel at high-speed drilling in soft rock formations. This unique shape facilitates the scooping and removal of cuttings for efficient penetration.
Customize Your Desired Cemented Carbide Buttons
Material Composition
We meticulously formulate our cemented carbide buttons using high-purity tungsten carbide powder and a cobalt binder. This precise composition ensures a perfect balance of exceptional hardness and toughness, which is critical for withstanding the intense impact and abrasive wear of percussive drilling, guaranteeing long-lasting performance.
Manufacturing Process
We utilize advanced manufacturing techniques, including pressing, sintering, and grinding, under stringent quality control. This process ensures every button has uniform density, flawless internal structure, and consistent physical properties. This meticulous approach guarantees the high reliability and durability of our cemented carbide products.
Application & Functionality
Our buttons are engineered to maximize drilling efficiency and tool life. They are designed to absorb and transfer powerful impact energy from the drill to the rock, effectively breaking and crushing material. This functionality ensures faster penetration rates and higher productivity across various mining and construction applications.
Customization
We offer extensive customization to meet the specific demands of your drilling operations. Whether you require adjustments to the button’s shape (e.g., spherical, ballistic), dimensions, or material grade, we can tailor our products to optimize performance for specific rock formations, providing a competitive edge.
