MCD Engraving Cutter Diamond Milling Cutter For Micro Diameter Engraving

Micro-Diameter MCD Engraving Cutter

1. R&D Objective
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.

2. Features & Advantages
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 Ra0.02-0.05μm, 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

3. Applications

Diamond inlays for gold/K-gold/platinum jewelry

Ultra-deep micro-font engraving

4. Tool Lifespan

PCD: 50-100x longer than tungsten steel equivalents

MCD: 3-5 workdays under standard operations

Industry Feedback: 98% user satisfaction rate

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