Trepanning
deep machining with material optimization
Trepanning is an advanced deep hole drilling technique that allows efficient, precise machining of large diameter holes with greater material utilization. Especially focused on sectors where raw material has a high cost (nickel alloys, titanium, etc.)
Instead of completely eliminating the metal core, as in conventional drilling, the trepanning process extracts an annular section, preserving the central material.
At TAES we use state-of-the-art trepanning systems, capable of working with diameters from 140 mm to 350 mm and depths of up to 11 meters, maintaining excellent straightness, adequate surface finish and tight tolerances.
This technology is especially useful in large pieces, complex geometries or manufactured with high-cost materials, where material savings and dimensional precision are key factors.
The process
Trepanning uses a tubular tool with cutting inserts distributed around the periphery.
In this process, the central core is preserved and can be reused as raw material for other purposes. During the process, oil is injected at high pressure to cool the cutting zone and evacuate the chips.
This method is applied to both solid parts and semi-finished components, allowing the machining of large diameters with high stability, minimal thermal deformation and excellent process control.
Furthermore, at TAES we can combine trepanning with subsequent operations such as burnishing and lapping, obtaining final results ready for assembly or inspection.
Application sectors
Trepanning is used in industrial sectors where material optimization, precision and process economy are determining:
- Energy and Oil & Gas: valves, manifolds, pump bodies, turbine shafts.
- Aeronautics: high-resistance components, landing gear systems, engine components, etc.
- Automotive and heavy transport: shafts, hydraulic cylinders and shock absorbers, transmission pieces.
- Iron and steel: rolling mills, high-pressure pipes.
- Industrial machinery: spindles, liners, pistons, casings and machine bodies.
- Defense: cannons, guide tubes, large caliber artillery pieces, ballistic tubes, and critical artillery pieces.
- Moulds and tools: cooling circuits, heating ducts and pieces with complex geometries.
- Wind: Main shaft, diver tube.
