Repairing small bores such as Ø70 is one of the most technically demanding challenges in precision mechanical restoration.
With a narrow diameter and limited space, the process requires extremely high accuracy, along with precise control of the heat input and cladding thickness to ensure strong bonding and coating quality.
Challenges in small bore cladding:
- Limited access, difficult to position the laser head
- Localized heat concentration, which may cause distortion or porosity
- Difficulty achieving uniform coating thickness along the full circumference
- Strict requirements for concentricity and roundness after machining
Our solution: Laser cladding technology
At Phuong Dong Industry, we apply high-power laser cladding combined with CNC rotary axis control, allowing precise deposition inside Ø70 bores and smaller.
This ensures correct alignment, exact sizing, and strong metallurgical bonding between the cladding layer and the base material.
Key advantages of small bore laser cladding:
- No deformation of the part
- Smooth, uniform cladding surface
- High dimensional and geometric accuracy after finishing
- Reduced downtime and lower replacement cost
With a team of highly skilled and experienced engineers, Phuong Dong has fully mastered the small bore laser cladding process – a highly demanding and precision-intensive technique.
We are committed to providing high-quality surface restoration solutions for even the most complex components.
