CAD CAM Dental Lab Burs Dental Milling Tools Metal Burs Bridge Dental Lathe Burs
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.
