Constrained by historical diamond grinding equipment and technical limitations, micro-scale jewelry engraving has relied on tungsten steel tools and 4-flute diamond cutters (both utilizing negative rake angle cutting, inherently prone to burrs). High-end products like inlaid jewelry, K-gold, and pure gold often suffer from compromised details due to tool limitations. Subsequent polishing erodes design integrity, causing texture loss and high rejection rates. This critical issue demands urgent resolution.

Our Micro-Diameter MCD Engraving Cutter (spec: D0.1xK6-15°) revolutionizes precision machining by replacing traditional 3-flute tungsten steel and 4-flute diamond tools. Key innovations:

• Hybrid Process: PCD roughing + WJ single-edge diamond finishing
• Surface Quality: Mirror-smooth bases with Ra0.02-0.05 μm, preserving diamond clarity and color integrity
• Wear Resistance: Minimal tool wear (PCD/MCD variants)
• Weight Control: ±1mg consistency across 10,000+ CNC parts
• Delivery Assurance: Unmatched process stability

• Diamond inlays for gold/K-gold/platinum jewelry
• Ultra-deep micro-font engraving

• PCD: 50-100x longer than tungsten steel equivalents
• MCD: 3-5 workdays under standard operations
• Industry Feedback: 98% user satisfaction rate

Achieves zero visible tool marks and sub-5 μm burr elimination on 18K gold surfaces.
