\ TURBINES’ SECTOR

Proyectos aeronáuticos y del sector de la energía.

Integridad superficial garantizada.

El control de cada descarga del generador digital garantiza la integridad superficial de las piezas incluso en las condiciones más estrictas. Las máquinas ONA AV y QX consiguen acabados perfectos sin micro grietas evitando la aparición de la capa de material refundido

\ Blisks

  • Blisk manufactured in an ONA EDM NX4C machine using single axis rotary table.
  • ONA developed an apparatus for machining each blade cavity using blocks of three electrodes with different shapesX.

\ NGV

  • Depth from 3.50 to 5.50 mm (0.137” to 0.217”).
  • Width from 0.40; to 0.80 mm (0,016” to 0,031”).
  • Workpiece Material: Nickel alloy.
  • Electrode Material: Graphite.

\ Honeycomb

ONA electroerosión usa un método se basa en un electrodo cilíndrico que rueda sobre el honeycomb. La ventaja es que se necesita menos potencia y se controla mejor la cantidad de material que se derrite.

\ Fir Tree

  • EDM is an alternative to broaching for being less expensive, easier and more rapidly to develop for new designs. It provides reasonable productivity compared to broaching.
  • Preliminary analysis shows the production cost of wire EDM fir-trees to be 50 % less than that of broaching.

\ Diffuser

Special electrode design.
Genetic Algorithm-based CAM for optimum definition of electrode paths based on the following criteria:

  • Maximum material removal rate for roughing.
  • Surface finish and geometric accuracy for finishing.

\ Anillo Corte Inclinado

\ Combustor Case

High volume of material rate removal is now possible. Casings that usually are fully machined by milling can be now roughed by EDM.

\ Impeller

High production costs of conventional machining of impellers require hybrid manufacturing solutions. EDM comes in place in parts with pronounced twist of the blades, in areas difficult to reach, whereas the volume of material to remove is high. Complex shapes like impellers and blisks require complex electrode and special tool path generation design.

\ Turbine Rings – Housing of Vanes

Special ONA large modular wire EDM machine.

  • Strictly controlled recast layer.
  • Tight tolerances.
  • Consistent and robust process.
