Counterboring
optimization of existing holes
Counterboring is an optimization process for existing deep holes, aimed at improving their precision and surface finish.
At TAES, we apply this technique on previously drilled pieces or commercial tubes that require diameter expansion, guaranteeing results that meet the most demanding standards of industrial sectors.
With our means and experience in deep precision machining, we can perform counterboring on pieces of great length and weight, maintaining good alignment and adequate control of the cutting process.
This service is key both for industrial repairs and for engineering adjustments in high-added-value pieces.
The process
Counterboring consists of reprocessing an existing hole, in order to:
- Correct axis deviations
- Enlarge the initial diameter within a new tolerance.
- Improve surface roughness
- Eliminate machining defects, wear, or internal corrosion.
The process can be carried out with gun drill, BTA tools and trepanning, depending on the diameter, depth and final quality required.
Application sectors
Counterboring is applied in all types of industries where machined pieces of:
- Aeronautics: Hydraulic and pneumatic systems, and landing gear, high-resistance components, landing gear systems, engine components, etc.
- Automotive: Precision work on elements as diverse as pre-machined or finished shafts for the most diverse applications, camshafts, gearbox shafts, hollow shafts to be mounted on adjustable shock absorbers or shafts for steering racks, shafts, hydraulic cylinders and shock absorbers, transmission pieces.
- Machinery construction: Gearbox shafts, reducer shafts, gears, spindles, headstock shafts, etc.
- Sporting weapons: Barrels and bolts
- Machining: All types of pieces and materials in which a hole of great depth relative to the diameter is necessary.
- Energy and Oil & Gas: valves, manifolds, pump bodies, turbine shafts.
- Iron and steel: rolling mills, high-pressure pipes.
- Industrial machinery: spindles, liners, pistons, casings and machine bodies.
- Defense: cannons, ballistic tubes and critical artillery pieces.
- Moulds and tools: cooling circuits, heating ducts and pieces with complex geometries.
