If your projects require intricate cutting or engraving, a CNC laser cutter will help you create clean, professional results with minimal effort.

6. CNC Electric Discharge Machines (EDM)

Some metals are just too tough for traditional cutting tools. If you’ve ever struggled with machining hardened steel or intricate shapes, you know how frustrating it can be. That’s where CNC Electric Discharge Machines (EDM) come in.

CNC EDM machines use electrical discharges (sparks) to shape metal instead of cutting it with a blade. The process happens under a dielectric fluid, which helps control the sparks and prevent overheating.

There are 2 main types of EDM machines:

• Wire EDM: Uses a thin wire as an electrode to cut through metal with extreme precision.
• Sinker EDM: Uses a shaped electrode to press into the material and erode it into the desired form, perfect for deep cavities and molds.
