Micro Diameter PCD Engraving Cutter High Precision With MCD CVD Diamond Material

Micro-Diameter PCD Engraving Cutter

National Utility Model Patent

1. R&D Objective
Traditional tungsten steel tools (hardness ~55 HRC) suffer from rapid tip wear at cutting speeds above S20,000 RPM with F1000 mm/min feed rates, leading to:

Reduced cutting paths and burr formation

Increased part weight from material adhesion

Frequent tool breakage and replacements

Compromised design integrity due to excessive polishing

This Micro-Diameter PCD Cutter resolves these critical machining challenges through advanced diamond technology.

2. Features & Advantages

Material Innovation: Utilizes PCD/MCD/CVD superhard diamond composites

Hybrid Machining Protocol:

Roughing: PCD tools at S100,000 RPM & F3,000 mm/min

Finishing: MCD/CVD tools for mirror finishes (Ra0.1-0.5μm)

Ultra-Precision Tooling:

Diameter range: 0.1-1.0mm (straight/ball-nose configurations)

Platinum machining compatibility

Process Control: ±1mg weight consistency across 10,000+ CNC parts

3. Applications

High-speed roughing/finishing of gold, K-gold, and platinum

Precision micro-engraving for luxury jewelry

4. Tool Lifespan

PCD: 100x longer vs tungsten steel tools

MCD/CVD: Process-optimized cycles (technical consultation required)

Industry Validation: 97% user satisfaction in mass production
