What is Spark?
An advanced technology (EDM) is the Spark method of molding that maximizes precision and detail.
Spark is a non-traditional machining method used to cut and shape hard and complex materials, such as hard metals and complex geometric parts.
In this method, electrical discharges, or sparks, are used to shape materials. Sparks are especially useful in molding and manufacturing precision parts with complex shapes.
For example, sharp corners or special shapes that cannot be made by CNC milling machines are made in this unit by spark machines on the mold.
Spark Benefits :
- High accuracy
- Reducing tensions
- Removing a small amount of material
- Ability to process hard materials
- Ability to process complex shapes
How Spark CNC and ZNC work:
An electrode, usually copper or graphite, and the workpiece are immersed in an insulating liquid such as oil or petroleum.
As the electrode approaches the workpiece in the horizontal and vertical axies, an electrical discharge or spark is created between them, which causes a point of material to melt and evaporate. These sparks are created sequentially and slowly remove the material from the surface of the workpiece and shape it into the desired shape.
