dental milling tools CAD/CAM Dental milling metal burs bridge

1. Product Introduction

ZrN-Coated Dental Metal Milling Burs are precision-engineered tools designed for milling dental bridge frameworks and titanium abutments. Featuring a robust steel substrate with a full-process zirconium nitride (ZrN) coating, these burs deliver exceptional wear resistance and dynamic balance for high-accuracy dental restorations.

2. Product Purpose

These burs are specialized for machining dental metals, including:

• Titanium abutments (optimized for alloy synergy)

• Bridge frameworks (cobalt-chromium, zirconia, etc.)
  They support full-process milling – from roughing to finishing – ensuring seamless transitions in complex dental restoration workflows.

• 

3. Key Advantages

• Enhanced Longevity: ZrN coating reduces wear by >60% vs. uncoated burs, extending tool life.

• Alloy-Specific Performance: Engineered for titanium compatibility, minimizing chipping and ensuring stable milling.

• Deviation-Free Precision: Dynamically balanced design eliminates vibration for <5µm carving accuracy.

• Process Adaptability: Single-bur system handles multiple specifications (shapes/sizes), reducing tool changes.

• 

4. Product Characteristics

• Coating: Full-process ZrN layer (3–5µm) on steel substrate for maximum abrasion resistance.

• Compatibility: Optimized for titanium abutments and common dental alloys (e.g., CoCr, Ti alloys).

• Precision System: Multi-specification bur range (e.g., cylindrical, tapered, spherical) with unified shank design.

• Dynamic Balance: ≤0.1g·mm imbalance tolerance for vibration-free, high-RPM (up to 60,000 rpm) operation.

• Efficiency: Integrated roughing-to-finishing capability with anti-clogging flutes.
