What is hole-drilling EDM or spark machining?
Hole-drilling EDM uses a hollow tubular electrode to create holes in a workpiece. The rotating tubular electrode uses spark discharge to drill a hole in a variety of materials such as iron alloys (e.g., steel), aluminum, copper, and carbide. An EDM drill operates completely computer-driven and therefore works very accurately.
During spark machining, rinse water is injected through the electrode at relatively high pressure. The residue flushes upward along the outside of the electrode. This makes it possible to create tiny and deep holes. Holes with a diameter of 1 millimeter in material 600 mm thick are one of the various possibilities at Ter Hoek.
Advantages of hole-drilling EDM
Hole-drilling EDM is particularly suitable for creating starter holes in a workpiece. This is also referred to as start hole EDM drilling and is often considered the first step in a further machining and development process. For example, starter holes are created, which are then used in wire EDM as through holes for contour cutting.
But EDM is also very suitable for making cooling or air ducts and supply-channel holes for oil or liquids. The machining possibilities of different types of (hard) metals with high speed and precision make this technique an excellent choice for (small) series and also widely applicable for various technical purposes.
EDM Drilling: A Smart Alternative to Laser Micro Jet Technology
While laser micro drilling and laser micro hole drilling offer high precision, they can sometimes cause thermal stress in delicate materials. In contrast, EDM drilling provides a non-contact solution that avoids heat damage, making it ideal for microholes in sensitive applications. Unlike the laser micro drilling process, EDM hole drilling ensures smooth, accurate results without micro-cracks. Whether you need laser drilling micro holes or EDM precision hole drilling, we offer expert guidance to determine the best method for your needs.
