What is Precision drilling of gas holes?
Precision drilling of gas holes capability for titanium components
Integrated manufacturing capability for Precision drilling of gas holes, 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 valve. Precision valve for Oil & Gas present unique challenges: Seat leakage Class VI (ANSI FCI 70-2) requires lapped sealing surfaces. Stem straightness ±0.02 mm over 500 mm.
| 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 |
