EDM Machining Value & Advantages

Traditional EDM serves as a supplementary process to conventional mechanical machining. It breaks through the limitations of hardness, geometry, precision and stress in traditional cutting, making it possible to manufacture high-hardness, ultra-complex and ultra-precision parts, and reshaping the process route of precision manufacturing. It is capable of machining deep cavities, narrow slits and special-shaped blind holes without cutting force, making it ideal for thin and low-rigidity parts, fillet cleaning, sharp corners and micro-structures.
