   • Unprecedented finish control: Adaptively initiates minimized surface recast layers and microcracks, thus creating mirror-like finishes directly on the dielectric device surface and in many cases minimize secondary polishing.
   • Reinforced electrode wear compensation: Complex software can predict and actively compensate for electrode wear during machining paths, ensuring dimensional accuracy throughout the operation, even with complex electrodes.

2. Unparalleled accuracy and accuracy (submicron level): Integration with ultra-precise linear scales, thermal compensation systems and vibration damper structures enables modern CNC EDM machines to achieve submicron geometric tolerance and surface finishes at all times below 0.1 µm RA. This accuracy is critical to components such as fuel injector nozzles, surgical implants and semiconductor tools.

3. Advanced detection and automated detection systems directly integrated into the EDM machine environment allow:

   • Automatic working settings: Position the workpiece accurately, define the benchmarks and eliminate tedious manual alignment.
   • Measurement and compensation in the process: Verify the dimension intermediate processing and automatically adjust the tool path to compensate for any deviations to ensure the right front result.
   • Seamless electrode calibration: Accurately measure electrode size and wear, triggering the automatic wear compensation setting.
   • Combined with robot parts processing and pallet chain change, this can be enabled Light-emitting manufacturing – Run complex EDM operations unattended, significantly improving productivity.

4. 5-axis function integration: Synergies between 5-axis CNC machining EDM is revolutionary. While Greatlight performs well in both, a technical marriage unlocks new possibilities:

   • Complex geometry makes it possible to: The tilted electrode or workpiece is eliminated "Vision" The limitations of traditional EDM. This allows for undercuts, deep cavity with draft angles, complex turbine blades, and complex internal features in a single setup – using conventional 3-axis EDM alone.
   • Best Electrode Method: The 5-axis movement enables the electrode to always tangentially towards the working surface, which can improve flushing efficiency and consistency of the surface finish even on the contoured surface.
   • Reduce electrode complexity: Generally, multiple complex electrodes can be replaced with a single, simple electrode strategically manipulated by 5 axes, thereby reducing electrode manufacturing time and cost.

5. Improved flushing technology: Effective debris removal is essential for stable processing and good finishing. Progress includes:

   • Intelligent flush control: Programmable pressure flushing is synchronized with processing cycles and electrode motion.
   • Jet flush: Accurate, high pressure jets targeting deep or challenging geometric shapes.
   • Flooding Processing Innovation: Advanced dielectric filtering and cycling systems maintaining dielectric purity is critical for micron-scale accuracy, especially during immersion.

6. Multitasking and hybrid concepts: The driving force of efficiency leads to:

   • EDM & Milling on a single platform: Machines combining EDM and high-speed milling can perform rough operations through milling and through EDM on the same setup and complex details.
   • Enhanced Wire EDM (WEDM): Similarly, Wedm has seen advancements such as multi-line systems and independent 4-axis control of the cone machine, thus greatly improving the productivity of complex 2D and complex 3D profiles.

7. Seamless CAD/CAM integration and simulation: Modern CAM software specifically targets EDM provides powerful simulation tools. Users can gradually visualize the entire machining process, including electrode movement, spark areas and expected material removal. This not only prevents expensive collisions and programming errors, but also optimizes electrode strategies and machining times.
8. IoT and data analysis: Leading EDM machines now have extensive connectivity. Sensor monitors key parameters (vibration, temperature, dielectric state, power consumption). This data is derived from the implementation analysis platform:

   • Predictive maintenance: Identify potential component failures before causing downtime.
   • Process optimization: Analyze historical data to specific materials and geometry of fine-tuning parameters for improved efficiency and quality consistency.
   • Remote monitoring and support: Technicians can remotely diagnose problems, ensuring maximum machine uptime.
