High-Speed Milling: The Third-Generation Mold Manufacturing Technology

High-speed milling has become a major advancement in mold manufacturing. Compared with traditional machining methods, high-speed milling offers:

• Higher machining speed
• Excellent surface finish quality
• Low temperature rise (workpiece increases only about 3°C)
• Minimal thermal deformation
• Reduced cutting force
• Suitable for thin-wall components
• Effective machining of low-rigidity parts
• Capability to machine hardened materials (up to HRC60)

Because of these advantages, high-speed milling continues to evolve toward:

• Intelligent machining
• Agile production
• Integrated manufacturing systems

This makes high-speed milling widely recognized as the third-generation mold manufacturing technology.

EDM Milling: Green Manufacturing Technology

Electrical discharge machining (EDM) technology has also advanced significantly. Modern EDM milling replaces traditional shaped electrodes with high-speed rotating tubular electrodes.

This allows:

• 2D and 3D contour machining
• Elimination of complex electrode manufacturing
• Improved machining flexibility
• Reduced production time
• Higher precision cavity machining

This innovation represents a major development in EDM forming technology.

Safety and Environmental Considerations in EDM Technology

As EDM technology evolves, safety and environmental protection have become increasingly important. Modern EDM equipment now includes:

• Radiation protection systems
• Improved electrical shielding
• Enhanced operator safety features
• Environmental compliance design

International regulations, such as CE certification requirements, have made safety technology essential for equipment entering global markets.

One of the main challenges in EDM machining is electromagnetic interference and radiation, which can impact both safety and environmental performance. As global markets increasingly demand environmentally friendly equipment, "green" EDM technology is becoming a critical direction for future development.

Future Trends in Mold Manufacturing

Modern mold manufacturing will continue to advance toward:

• Intelligent manufacturing systems
• Integrated digital production
