What is Plate laser cutting + CNC drilling of flange bolt holes?

Plate laser cutting + CNC drilling of flange bolt holes capability for titanium components

Precision machining capability for Plate laser cutting + CNC drilling of flange bolt holes, utilizing multi-axis CNC centers with in-process inspection and SPC quality control.

Engineering Parameters & Capabilities

Fiber laser cutting of titanium uses a focused 1 µm wavelength beam to melt and expel material through a coaxial assist gas jet. The narrow (0.1–0.3 mm) and small heat-affected zone make it suitable for precision profiles in sheet and thin-plate titanium components, specifically for flange. Precision flange for Aerospace, Chemical, Oil & Gas present unique challenges: Large diameter (up to 600 mm) with bolt hole pattern PCD tolerance ±0.1 mm. Face flatness critical for seal integrity.

Parameter Primary Method Alternative Method
Cut Speed (3 mm Ti) Up to 6 m/min 0.5–1.5 m/min
Kerf Width 0.1–0.3 mm 0.7–1.2 mm
HAZ 0.05–0.15 mm with N₂ assist Zero HAZ (cold cut)
Max Thickness 15 mm (fiber laser) 100 mm+

Engineering Capabilities & Limits

Precision machining capability for Plate laser cutting + CNC drilling of flange bolt holes, utilizing multi-axis CNC centers with in-process inspection and SPC quality control.

Hole Types Supported

Round holes (≥ 0.5 mm diameter) Slots / oblongs Micro-perforation arrays

Heat Control Measures

Coaxial N₂ (99.999%) assist gas at 12–20 bar prevents titanium oxidation by displacing oxygen. Laser power modulation controls heat input to minimize HAZ to 0.05–0.15 mm.

Flatness & Stress Relief

Face flatness critical for seal integrity. Sequenced bolt-hole drilling pattern (opposite poles) prevents flange warpage.

Tolerance

+0.05 mm (bolt PCD) / +0.02 mm (face flatness)
