Deep hole drilling (tube sheet) capability for titanium components
What is Deep hole drilling (tube sheet)?
Deep hole drilling (tube sheet) capability for titanium components
Integrated manufacturing capability for Deep hole drilling (tube sheet), 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 tube. Deep tube for Chemical, Aerospace, Medical present unique challenges: Wall thickness uniformity (±0.05 mm) over long lengths. Internal surface finish Ra < 0.8 µm for fluid flow. 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 |
