EDM MICRO-DRILLING WITH 5-AXIS CNC MACHINES

SILMEC Srl, high-precision micro-drilling. We combine the accuracy of EDM technology with the versatility of 5-axis machining. Great precision and finish even in the most difficult applications.

5-axis EDM micro-drilling is a technology that, at SILMEC, we know how to govern with the maximum flexibility required by the various industrial sectors, both because of our particularly well-suited fleet of machines and because of the vast experience we have accumulated over the last 10 years working for well-known companies in the energy sector.

Our Capabilities

SILMEC is equipped with CNC wire EDM machines capable of 5-axis movement with continuous wire feed systems. We work in accordance with international quality standards and can guarantee reliable and safe machining. The 5-axis configuration allows us to significantly increase flexibility, enabling complex machining in 3 dimensions:

  • Linear axes: X, Y and Z for workpiece positioning
  • Rotary axes: A and B for workpiece or electrode rotation for specific angles

These features allow us to create:

  • inclined holes on curved or irregular surfaces
  • multiple holes on three-dimensional components without intermediate repositioning

Advantages of EDM micro-drilling

The high precision of this machining, which allows tolerances in the order of a few microns, and achieves extremely low surface roughness without the need for additional finishing, offers numerous advantages for many industrial contexts:

  • Geometrical versatility: machining holes with variable orientations allows complex applications for components with difficult geometries used in strategic industries
  • Extreme micrometric precision: the use of modern machinery allows us to produce microscopic holes with very tight tolerances, which is essential for gas turbine blades and sectors, for example
  • Surface quality: the typical feature of EDM technology is that it guarantees excellent finishes, a very important aspect especially for parts made from high-performance super alloys
  • Repeatability and reliability: the process is precise and repeatable for each machined part, ideal for mass production with guaranteed precision and tolerance compliance
     
Applications
  • EDM Micro-Drilling is used in various industrial sectors to manufacture critical and precision components:
  • Power Generation:

    Microscopic drilling with extremely tight tolerances in gas turbine blades and segments. The precision of micro-holes enhances airflow management and cooling, increasing turbine lifespan and efficiency.

  • Aerospace

    Micro-holes on turbine blades: the network of micro-holes ensures a precise flow of cooling air, improving thermal resistance and component durability. The same principle applies to micro-holes in actuators and valves, which regulate the flow of hydraulic fluids or gas to ensure precise movement of components.

  • Medical Sector:

    Machining of piezoelectric ultrasonic inserts used in advanced surgical and diagnostic instruments. EDM-drilled inserts enhance the performance of ultrasonic instruments used in surgery and diagnostics.
