What kind of manufacturing process does the Komatsu excavators high lifespan 400 rock teeth PC400RC use to improve its durability?

Komatsu excavators high lifespan 400 rock teeth PC400RC uses a forging process to improve its durability. Specifically, the forging process is a process that heats metal materials to a high temperature and then uses a press or other tools to pressurize and deform them to obtain metal products with the required shape and performance. In the manufacturing process of the Komatsu excavators high lifespan 400 rock teeth PC400RC, the application of the forging process brings several advantages, thereby significantly improving its durability.
During the forging process, the metal material is heated to a temperature close to its melting point, at which point the material becomes soft and has good plasticity. Subsequently, under strong mechanical pressure, the material is forcibly changed in shape. During this process, the loose areas and pores inside the material are filled by the surrounding metal flow, thereby significantly reducing or even eliminating these defects. This increase in density directly enhances the structural strength of the bucket teeth, allowing them to withstand greater impact and pressure without being prone to breakage or deformation.
The high temperature and pressure during the forging process help to refine the grains of metal materials, making the grain boundaries clearer and improving the mechanical properties of the material, including enhanced strength, hardness and wear resistance.
The forging process is not just a simple shaping of metal materials, but also a complex material modification process. By precisely controlling parameters such as temperature, pressure, and deformation rate during the forging process, the internal structure of the metal material can be optimized. This optimization includes eliminating non-homogeneous regions in the material, promoting the formation of beneficial phases, and adjusting the distribution of phases, thereby significantly improving the overall performance of the bucket teeth. The optimized organizational structure is more uniform and dense, which not only improves the strength, hardness and wear resistance of the bucket teeth, but also improves its fatigue resistance and corrosion resistance, and extends its service life.
The forging process makes the surface of the bucket teeth smoother and harder, reducing wear caused by friction during use, thereby extending the service life of the bucket teeth. According to relevant data, forged bucket teeth have a 20% increase in service life and wear resistance compared to cast bucket teeth.
To sum up, Komatsu excavator’s high-life 400-tooth PC400RC uses forging technology to significantly improve the durability of the bucket teeth, allowing it to maintain stable performance in harsh working environments.
