Discharge grinding of medical mold parts

Discharge grinding is a precision machining process that uses an electrically charged abrasive wheel to remove material from a workpiece. It is commonly used in the production of medical mold parts, which require high precision and accuracy.

The process involves placing the workpiece in a tank filled with a dielectric fluid, such as oil or water. An electrode is then positioned close to the workpiece, and an electrical discharge is created between the electrode and the workpiece. This discharge generates heat, which melts a small amount of material from the workpiece. The abrasive wheel then removes the melted material, creating a precise and accurate shape.

Discharge grinding is particularly useful for producing complex shapes and contours, as it can easily remove material from hard-to-reach areas. It is also a highly repeatable process, ensuring consistent quality across multiple parts.

In the production of medical mold parts, discharge grinding is often used to create features such as small holes, thin walls, and intricate details. The process is also used to achieve tight tolerances and surface finishes, which are critical for medical applications.
