Ø15mm Tungsten Carbide High-Speed EDM Roughing
Core Technology of High-Speed EDM Machining for Tungsten Carbide
Tungsten carbide is an extremely hard material that can be challenging to machine using conventional cutting tools. EDM technology enables efficient material removal without direct mechanical cutting, making it suitable for machining hard materials such as tungsten carbide.
NEUAR CNC EDM technology supports high-speed roughing of tungsten carbide, helping reduce machining time while preparing the workpiece for subsequent finishing operations.
