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

Frequently Asked Questions

What titanium grades are suitable for Tube sheet drilling?
Tube sheet drilling can be performed on Grade 1, Grade 2, Grade 5 (Ti-6Al-4V), Grade 7, and other grades. The specific grade selection depends on the required mechanical properties, corrosion resistance, and end-use application requirements.
What tolerances can be achieved with Tube sheet drilling?
Typical achievable tolerances for Tube sheet drilling are +0.02 mm (hole diameter). Tighter tolerances may be possible depending on part geometry, material condition, and quantity. Our engineering team reviews each project to determine the optimal tolerance-cost balance.
What quality certifications apply to Tube sheet drilling?
All Tube sheet drilling operations are performed under ISO 9001:2015 — Quality Management System, AS9100D — Aerospace Quality Management, ASTM B265 — Titanium Strip, Sheet, and Plate Standard certified quality management systems. Full traceability documentation, material certifications (EN 10204 3.1), and inspection reports are provided with each shipment.
What is the typical lead time for Tube sheet drilling projects?
Lead times for Tube sheet drilling vary by complexity and quantity. Prototype quantities (1-10 units) can typically be completed in 3-7 business days. Production quantities require 15-25 business days. Rush orders are available for qualifying projects. Contact our sales team for a specific timeline.
