CNC Sinker EDM Machines

CNC Sinker EDM machines operate by generating controlled electrical discharges between a precisely machined copper or graphite electrode and the workpiece within a dielectric fluid environment. This technology enables the exact geometry of the electrode to be reproduced on hardened steels, carbides, and specialty alloys with micron-level accuracy.

The next-generation CNC Sinker EDM machines offered by Ingenium Makine provide reliable solutions for plastic injection mold manufacturing, forging dies, precision component production, aerospace applications, defense industry projects, blind cavities, threading operations, and complex internal geometries.


Key Features of Our CNC Sinker EDM Technology

  • Minimal Electrode Wear (Low Wear): Advanced intelligent generator technology automatically optimizes discharge parameters, minimizing wear on copper and graphite electrodes while reducing operating costs.
  • Superior Surface Finish and Accuracy: Multiple micro-discharge combinations produce smooth, homogeneous surfaces that minimize the need for grinding and polishing operations in mold cavities.
  • Multi-Axis Orbiting Functions: The advanced CNC control system performs intelligent orbital movements in spherical, circular, conical, and lateral directions, enabling the machining of complex side channels and reverse-angle geometries in a single setup.
  • Advanced Safety and Arc Detection Systems: Integrated sensors instantly detect carbon build-up and abnormal arc conditions, automatically stopping the discharge process to protect both the electrode and the workpiece.

Industrial Stability: Reinforced cast iron machine construction and precision linear guide systems provide stable machining performance, even when processing large mold blocks weighing several tons, while maintaining micron-level accuracy.

Frequently Asked Questions About Sinker EDM Solutions

Click on the questions below for detailed information.

Should Copper or Graphite Electrodes Be Preferred in Sinker EDM?

Copper electrodes are preferred for precision plastic injection molds and detailed machining applications due to their excellent electrical conductivity and ability to maintain sharp corners. Graphite electrodes offer higher material removal rates and are particularly advantageous for machining large mold cavities and reducing production time.

Why Are Dielectric Fluid Quality and Filtration Important?

In Sinker EDM machining, dielectric fluid cools the discharge zone while simultaneously removing eroded metal particles from the machining area. Effective filtration and clean dielectric fluid help prevent unwanted arcing, improve machining stability, and enhance surface quality.

Does the CNC Control System Include Predefined Machining Libraries?

Yes. Our CNC control systems include advanced technology libraries that automatically select the optimal current and discharge parameters based on the workpiece material, electrode type, and desired surface finish requirements.
