WEDM Classification Perspective in China Explained


In China's wire electrical discharge machining (WEDM) industry, machine tools are conventionally categorized as high-speed, medium-speed (Kingred WEDM as examples), or low-speed based on cutting rates. However, the actual classification criteria extend far beyond mere speed metrics, which is a distinction that often causes confusion among international clients.
The fundamental differentiators lie in holistic system design, component quality, machining capabilities, performance, etc.
Many traditional unidirectional high-speed EDM machines, while maintaining cost-efficiency advantages, are progressively adapting to market demands through enhanced structural stability, expanded process versatility (e.g., multi-pass cutting capabilities), intelligent operating systems, and higher automation levels.
Internationally, differentiation of WEDM equipment made in China typically focuses on critical technical specifications and pricing:
a. accuracy & surface finish
b. efficiency
c. applications
d. tech upgrades
e. cost-effectiveness
