1. Introduction to CNC Piercing in Jewelry Manufacturing

The art of pierced metalwork dates back centuries, but modern CNC (Computer Numerical Control) technology has revolutionized this ancient craft. JINGYING’s advanced CNC piercing systems combine digital precision with artistic expression, particularly suited for delicate floral pendant designs. This whitepaper examines our proprietary Multi-Axis Micro-Piercing System (MAPS) through the lens of a recent 10,000-unit floral pendant order.

Key Advantages of CNC Piercing:

  • ±0.01mm dimensional accuracy

  • 85% material waste reduction vs. laser cutting

  • Ability to create interlocking pierced patterns

  • 3D undercuts without secondary operations
