Description
U47 Cutting Picks fitting Miner Cutting Systems
Primary Features
- Aggressive Heavy-Duty Penetrator: We equip the U47 with a massive, highly concentrated tungsten carbide tip. Engineered specifically for high-tonnage mining, it effortlessly shatters hard coal seams, shale, and rock, delivering maximum extraction rates with minimal drag on your shearer drums.
- Stepped Shank: We specifically design the mounting shank with an industry-proven stepped profile. This critical geometry ensures a rock-solid fit inside the holder, while giving underground crews a clear leverage point to instantly pry the tooth out.
- Self-Sharpening Rotation: The precision-machined cylindrical shank allows the tooth to rotate completely freely during continuous cutting. This smooth rotation guarantees the carbide tip wears perfectly evenly, maintaining a sharp penetrating point and preventing the tool from wearing flat.
- Fully Customizable Configuration: We can easily adjust the carbide grade, head profile, and specific shank dimensions to meet your precise requirements. As a direct manufacturer, we provide a highly reliable, cost-effective drop-in replacement for your entire mining fleet.
Manufacturing Quality
- Advanced Induction Brazing: We bond the heavy-duty carbide tip to the steel core using a strictly controlled induction brazing process. This creates a deeply secure, impact-absorbing joint that completely prevents the carbide from tearing out under extreme underground torque.
- Severe-Duty Heat Treatment: We rigorously heat-treat the entire forged steel body. It achieves the perfect metallurgical balance—delivering extreme surface hardness to combat abrasive coal flow, while maintaining a highly ductile core to absorb violent, continuous mining shocks without snapping.
- Precision CNC Machining: We machine the stepped shank and the bottom retaining groove to strict CNC tolerances. This guarantees a flawless fit with standard locking clips, keeping the tooth securely locked in place while ensuring safe, frustration-free tool replacements.
Applications
We build this severe-duty conical pick for high-volume subterranean extraction:
-
Underground continuous miners and longwall shearers
-
Heavy-duty roadheaders and surface mining equipment
-
High-volume extraction of coal, potash, salt, and medium-hard rock
-
Operations requiring maximum tool reliability and fast field replacements
