1. Corrosion damage to parts

In order to prevent corrosion of parts, corrosion-resistant materials such as nickel, chromium, zinc, etc. are often used to coat the surface of metal parts, or to coat and coat the surface of metal parts with oil. (Listed as planetary gear.sun gear. Swing Ring Gear etc. )

Non-metal parts, with anti-corrosion paint, etc. Direct contact with hazardous media. By improving the surface finish of the part, the potential difference on the surface of the part can also be reduced.

2. Fatigue damage of parts

Manifestations: fracture, surface peeling (such as excavator bucket Pin  and excavator bushing.step collar bush. dotted bush ). Some inferior excavator bucket Pin are easy to wear or even break, and high-quality bucket Pin are more practical with high strength and long life.

Our processing method: improve the surface finish of the parts during the manufacturing process, and adopt a relatively gentle section filter to reduce the stress concentration of the parts. In addition, the use of carburizing, quenching and other methods to improve the hardness, toughness and wear resistance of parts can also receive good results.
