What 5 Axis Laser Drilling can offer you
5-Axis Laser Drilling uses a tightly focused, high-powered laser beam to produce small-diameter holes with exceptional positional accuracy across complex curved and contoured surfaces. Unlike conventional mechanical drilling, there is no physical contact between tool and workpiece — material is removed through rapid, localised melting and vaporisation driven by the focused laser energy. This eliminates tool breakage, removes the risk of work-hardening the hole wall, and makes the process entirely independent of material hardness.
With full five-axis motion, holes can be drilled at precise compound angles on three-dimensional components in a single setup. This is essential for aerospace turbine components where cooling holes must be positioned and angled with exacting accuracy relative to complex curved aerofoil surfaces — re-fixturing between operations introduces positional error and adds significant cost and lead time. Five-axis laser drilling removes that risk entirely.
As with our laser cutting operations, assist gas selection is matched to the material being processed. Argon is used for titanium to shield the hole and surrounding material from oxidation, preserving the integrity and fatigue properties of the parent material. Nitrogen is used for stainless steel to produce clean, oxide-free hole walls. This careful gas management is particularly important for aerospace-grade components where surface condition and material integrity around the hole directly influence part life and performance.
Laser drilling is capable of producing holes from sub-millimetre diameters upwards in materials that present significant challenges to conventional drilling — nickel superalloys, titanium alloys and stainless steels used extensively in turbine blades, combustion liners, heat shields and structural aerospace components. The non-contact nature of the process means even the most delicate or thin-walled components can be drilled without distortion or stress introduction.
At Electro Discharge Ltd, our laser drilling operations are fully integrated with our broader laser and EDM capabilities, and are supported by in-house CAD/CAM programming and inspection. All work is carried out within our AS9100 Rev D accredited quality management system, with full traceability and dimensional verification available on request — giving customers confidence that every hole is where it needs to be, every time.
