Tube sheet drilling
Tube sheet drilling capability for titanium components
What is Tube sheet drilling?
Tube sheet drilling capability for titanium components
Integrated manufacturing capability for Tube sheet drilling, supported by in-house QC, material certification, and engineering review.
Engineering Parameters & Capabilities
Laser drilling of titanium uses pulsed laser energy to create precise holes through percussion or trepanning methods. Hole diameters range from 0.05 mm to 3 mm with aspect ratios up to 20:1, specifically for tubes. Precision tubes for chemical, aerospace, and medical applications present unique challenges: wall thickness uniformity (±0.05 mm) over long lengths, internal surface finish Ra < 0.8 µm for fluid flow, and bent tube ovality control.
| Parameter | Primary Method | Alternative Method |
|---|---|---|
| Hole Diameter | 0.05-3 mm | 0.5 mm min (abrasive) |
| Aspect Ratio | Up to 20:1 | 3:1 |
| Speed | 0.1-2 sec/hole (percussion) | N/A |
