Sinker EDM Services

Electrical Discharge Machining Capabilities

Sinker EDM utilizes a series of EDM pulses between a custom tool-electrode and a workpiece to create a desired shape without damaging or stressing the workpiece. RDL Machine Inc specializes in CNC Sinker EDM (Electrical Discharge Machining), and can provide low-risk machining solutions for complex components and parts with previous machining already completed.

We have experience machining assemblies, subassemblies and large quantities of metal components. As an ISO 9001:2015 and AS9100D certified manufacturer of precision, mission-critical metal parts, we understand the imperative for quality and performance in every product we create. Our skilled machinists can create complex components and high-volume parts under fast turnaround times.

Sinker EDM Benefits

Sinker EDM offers the ability to machine shapes without inducing stresses into the electrically conductive material and provides. This non-contact machining process is ideal when looking to minimize machining risk and achieve reliable components. Using a Sinker EDM allows you to machine any material as long as the material is conductive. Additional benefits include:

  • Produce Complex Shapes
  • Unparalleled Accuracy
  • Machining Hard Materials
  • Minimal Mechanical Stress on the Workpiece
  • High Processing Speed
  • Minimized Material Loss

Sinker EDM Capabilities

We utilize the Sodick AG6oL series EDM sinker featuring linear drive technology and simplified control mechanisms. This provides a direct link between the drive and the control to ensure the fastest servo response and optimal spark gaps. Additional features include but are not limited to:

  • Linear motor (X/Y/Z axis)
  • Absolute Linear scale (X/Y/Z axis)
  • Ceramic components
  • Linear motor cooling unit
  • Dielectric fluid cooling unit

Sinker EDM for Multiple Industries Industry

Sinker EDM is typically used to create holes or cavities in a conductive component. The holes that are created have complex shapes that couldn’t be manufactured by traditional CNC milling processes. This machining process is incredibly accurate and requires only simple tooling, making it ideal for industries requiring reliable, mission-critical components. Frequent industries served include Aerospace, Medical, Power Generation and more.

Sinker EDM Applications

Our machinists can create components from soft or hard materials such as titanium, tungsten, carbide, Inconel, aluminum, copper, brass and more. We have experience creating Molds, Die Sets, Tool and Die parts and other components for low and high-volume projects. Sinker EDM can customize components for a variety of applications, including:

  • Blind Cavities
  • Thin Walls
  • Fine Finishes
  • Sharp Corners
  • Machining Threads & More
  • Blind Keyways
  • Internal Splines, Squares or Hexes
