Hydraulic Excavator Bucket Teeth Classification

The classification of hydraulic excavator bucket teeth mainly depends on their structural form and applicable working conditions.
Structurally, they are divided into one-piece and two-piece types. Modern excavators generally use a two-piece design, which consists of a tooth seat welded to the bucket lip and a tooth tip connected by a pin. This design greatly improves the convenience and economy of replacement.
For different working materials, such as soil, rock, or gravel, the tooth tips are designed in different shapes such as standard type, rock type, and reinforced type to achieve the best balance between insertion force, wear resistance, and impact resistance.

The manufacturing of bucket teeth is a technology that integrates materials and processes, and its core lies in casting and heat treatment. High-quality alloy steel is cast into shape after smelting, and precision casting processes such as lost foam casting are widely used to ensure the density and dimensional accuracy of the castings. After casting, the bucket teeth need to undergo crucial quenching and tempering heat treatment. This process determines their final mechanical properties, making them have both extremely high surface hardness to resist wear and sufficient core toughness to withstand impact. Subsequent machining mainly focuses on the precision drilling of pin holes to ensure the assembly accuracy with the tooth seat. Finally, through quality inspection and painting, the manufacturing of a reliable bucket tooth product suitable for specific harsh working conditions is completed.
