Trepanning Services
Large Diameter Trepanning for Heavy-Duty Engineering
At Robinsons Precision Engineering, we provide specialist trepanning services designed for large-scale steel and alloy components. Trepanning is a deep hole boring technique that removes a solid core, making it an ideal solution when traditional drilling is inefficient or cost-prohibitive for large diameters.
Why Choose Trepanning?
Trepanning offers several advantages over conventional drilling, especially in heavy engineering applications:
- Faster material removal for large bores
- Reduced tool wear and heat build-up
- Allows recovery of solid bar cores
- Suitable for thick-walled or solid steel sections
