Electric Spark Machine FAQ
What materials can be processed with an Electric Spark Machine?
Our Electric Spark Machine can process virtually all conductive materials including hardened steel, titanium alloys, tungsten carbide, copper, aluminum, and exotic superalloys. The process is particularly effective for materials that are difficult to machine using conventional methods. The only limitation is that the material must be electrically conductive.
How does the accuracy of an Electric Spark Machine compare to CNC milling?
Electric Spark Machines typically achieve higher precision than CNC milling, especially for complex geometries and hard materials. While CNC milling might achieve ±0.02mm tolerances, our Electric Spark Machine can consistently maintain ±0.005mm or better. Additionally, EDM doesn't create mechanical stresses in the workpiece, eliminating distortion issues common with milling.

Electric Spark Machine FAQ
What maintenance does an Electric Spark Machine require?
Regular maintenance for an Electric Spark Machine includes daily dielectric fluid checks, monthly filter replacements, quarterly guideway lubrication, and annual professional servicing. The electrode holder and worktable should be cleaned after each use. Our machines feature self-diagnostic systems that alert operators to required maintenance, significantly reducing unexpected downtime.
How long does the typical electrode last in an Electric Spark Machine?
Electrode life varies significantly depending on material and machining parameters. Graphite electrodes machining steel might last 50-100 hours, while copper electrodes might last 20-50 hours. Our machines include electrode wear compensation systems that automatically adjust for wear, maintaining accuracy throughout the electrode's lifespan.
Can an Electric Spark Machine create sharp internal corners?
Yes, one of the key advantages of Electric Spark Machines is their ability to produce sharp internal corners that would be impossible with milling. The process can achieve inside corner radii as small as 0.05mm, making it ideal for mold cavities with intricate details. This capability comes from the non-contact nature of the process and the ability to use precisely shaped electrodes.
