Common Questions About Sinker EDM

In this section, we’ll answer some frequently asked questions about sinker EDM processing.

  • What is EDM sinking?

    EDM refers to electrical discharge machining, also known as die sinking, and is a process that uses electrical sparks to erode material, an electrode, into a pre-determined shape. The electrode is then brought close to the workpiece and submerged in a dielectric fluid. A controlled electrical discharge between the electrode and workpiece creates precise cavities in the material, reflecting the electrode's shape. 

  • What is the difference between wire EDM and sinker EDM?

    Wire EDM, also known as wire cutting, involves a thin wire used as an electrode that slices through metal by means of a spark discharge. By contrast, with sinker EDM, we use an electrode in the shape of the desired cavity and electrically discharge it onto the workpiece.


    Both techniques leverage electrical discharges to cut or mold hard materials, but their applications and capabilities are distinct and tailored to the specific needs of the particular job.

  • What are the applications of sinker EDM?

    The sinker EDM process has many applications, and since it creates intricate cavities, it’s often used for making things from hard materials, such as:

    • Blind cavities
    • Dies
    • Molds
    • And much more

  • How accurate is sinker EDM?

    Sinker EDM is well known for its exceptional precision, capable of achieving unbelievable accuracy. This high level of precision is indispensable for creating components with meticulous details and tight tolerances.

    What are the advantages of sinker EDM?

    There are a slew of reasons to use sinker EDM, such as:

    1. Precision: Surface finishes are smooth
    2. Efficiency: Fast process
    3. Functionality: Produces intricate shapes that other methods can’t match

  • Are there any disadvantages to sinker EDM?

    Like anything else, sinker EDM has disadvantages as well as advantages. For example, the operating costs can be high. This is because the spark erosion used in these kinds of machines requires a ton of electricity. Also, sinker EDM machines aren’t able to machine composites or plastics.
