Polycrystalline Diamond Compact (PDC) cutters are engineered by fusing a layer of synthetic diamond crystals to a tungsten carbide substrate under extreme heat and pressure. With exceptional hardness and wear resistance, these advanced materials have transformed drilling and high-precision machining operations worldwide.
Properties of PDC Cutters
1. Extreme Hardness & Impact Resistance
- 10,000+ HV Hardness: 3× harder than tungsten carbide
- Superior Wear Resistance: Lasts 10× longer than conventional carbide tools
- 1,500 MPa Bending Strength: Withstands intense drilling impacts
Industrial Impact: PDC drill bits penetrate tough formations (sandstone, limestone, igneous rock) and resist fracture in gravel layers, significantly extending service life.
2. Unmatched Thermal Stability
- Operates reliably at 200°C+ in deep-well drilling
- Withstands 750°C short-term exposure (2 minutes)
- Resists thermal cracking/deformation
Proven Performance: PDC bits maintained 80+ hours of continuous operation at 200°C in Xinjiang’s Karamay Oilfield.
Critical Industrial Applications
1. Drilling Applications (Oil & Gas)
Optimal for: Soft-to-medium hard formations (sandstone, limestone)
Advantages:
- High thermal stability in complex geology
- Custom geometries (flat, grooved, chamfered)
- Surface treatments (polished, ground) for specific needs
Industry Role: Indispensable for modern oil/gas drilling operations due to reliability in variable strata.
2. Precision Machining & Cutting Tools
Processes: Turning, milling, and finishing of non-ferrous materials
Ideal for Cutting:
- High-hardness alloys
- Non-metallics (ceramics, composites)
- Wood and non-ferrous metals
Performance Advantages:
- Micron-level cutting accuracy
- Reduced tool-change frequency
- Superior surface finish quality
Sector Applications:
- Aerospace: Engine component machining
- Automotive: High-volume piston/rotor production
- General CNC: Wear-resistant inserts, drill tips, lathe tools
