Material Selection: Strength Meets Resilience

To withstand the extreme forces exerted during rock-breaking operations, high-grade alloy steel is used in the production of chuck housings. This material is chosen for its:

✔ High tensile strength – Ensuring resistance to impact and deformation.
✔ Superior wear resistance – Reducing maintenance frequency and extending service life.
✔ Corrosion protection – Enhancing durability in harsh working conditions.

Manufacturing Process: Precision Engineering for Maximum Performance

1. Raw Material Selection & Inspection

Only premium-quality forged or cast steel is selected for chuck housing production. Each batch undergoes rigorous quality checks to eliminate material defects.

2. CNC Machining for Extreme Precision

The chuck housing is precisely machined using CNC (Computer Numerical Control) technology, ensuring:

? Accurate hole alignment – For seamless fitting with the hydraulic hammer.
? Smooth surface finish – Minimizing friction and wear.
? Tight dimensional tolerances – Maximizing operational efficiency.

3. Heat Treatment for Enhanced Strength

To improve wear resistance and hardness, the chuck housing undergoes heat treatment processes such as:

? Quenching & Tempering – Strengthening the material structure to withstand repeated high-impact forces.
? Induction Hardening – Providing additional surface durability in critical contact areas.

4. Surface Coating for Corrosion Resistance

A protective surface treatment is applied to prevent rust and corrosion, ensuring longevity even in the most demanding environments. This may include:

✔ Phosphate coating – For enhanced lubrication and reduced friction.
✔ Nickel plating – Providing additional resistance against harsh weather conditions.
