Detailed Explanation of Bucket Connector Machining Process

The manufacturing process of bucket connectors begins with the die forging of high-strength alloy steel. Forging not only shapes the basic outline of the adapter but, more importantly, uses immense pressure to ensure that the internal metal streamlines are evenly distributed along the shape. This eliminates material defects and significantly enhances the overall toughness and impact resistance of the part, which is the foundation for its ability to withstand huge impact loads in harsh working conditions.

After initial surface cleaning, the forged blank enters the machining stage, primarily using CNC machining centers. First, rough machining of the non-mating surfaces is performed using milling and turning processes to quickly remove most of the machining allowance. Subsequently, the core of the machining focuses on two key areas: the mounting holes/surfaces for connecting to the bucket body, and the precision locking grooves for installing the bucket teeth. These areas have extremely high requirements for dimensional tolerances, form and position tolerances, and surface finish. High-speed precision milling and boring are typically performed using cemented carbide tools to ensure the absolute accuracy of their shape and position, guaranteeing that the bucket teeth can be quickly and securely locked and easily replaced after wear.

After machining, the adapter must undergo quenching and high-temperature tempering heat treatment to obtain extremely high surface hardness to resist wear, while maintaining the cores toughness to absorb impact. The slight deformation and surface oxidation caused by heat treatment need to be corrected by the final precision grinding process, especially grinding the working surface of the key locking grooves to restore their precise geometric shape and smooth surface, ultimately ensuring the reliability and durability of the bucket tooth locking mechanism.
