Spark erosion polishing

Spark erosion polishing is a process used in surface finishing to create precise and fine surfaces. This process is based on the principle of spark erosion, also known as EDM (Electrical Discharge Machining), but it is used specifically for polishing workpieces.

During spark erosion polishing, an electrical pulse is generated between a tool (electrode) and the workpiece to be processed. This pulse generates microscopic discharges that remove tiny particles of material from the workpiece. Compared to conventional machining, EDM polishing enables precise control over material removal and produces surfaces with greater accuracy.

The advantage of this process lies in its ability to process complex shapes and areas that are difficult to access. The process can be used for the surface treatment of workpieces made of metals, ceramics or hard metals. It also enables high surface finishes to be achieved without causing mechanical deformation or stress.

Spark erosion polishing is often used in the manufacture of precision tools, mold making and in the aerospace industry. It offers a precise method of achieving high-quality surfaces, with applications ranging from small components to complex molds.
