Processing Performance & Quality Assurance

Material Compatibility

  • Ultra-Hard Materials: Diamond, cubic boron nitride (CBN), tungsten carbide
  • High-Melting Metals: Rhenium, tungsten, titanium alloys
  • Ceramics/Semiconductors: Zirconia, silicon carbide, gallium arsenide
  • Sapphire (Key Advantage): Supports micro-drilling of sapphire (Al₂O₃) sheets (0.1–5mm thickness), overcoming brittleness issues in traditional machining.
  • General Metals: Stainless steel, carbon steel, aluminum alloys

Processing Capabilities

  • Hole Range: φ0.1–5mm (customizable for smaller diameters)
    - ​Depth: 0.01–10mm (multi-layer stepped holes supported)
    - ​Taper: 0°–30° adjustable

Quality Advantages

  • Geometric Precision: Hole diameter tolerance ±5%, taper error <0.1°, cylindricity >99.9%
  • Surface Finish: Ra≤0.8μm (mirror finish), no burrs or melt residue—critical for brittle materials like sapphire.
  • Stability: Temperature drift <±1μm after 8 hours of continuous operation; yield rate >99.5% (tested on typical materials).

Breakthrough Technologies

  • Ultrashort Pulse Mode​ (optional): Pulse width ≤10ps, heat-affected zone <1μm—ideal for sapphire and other thermally sensitive materials.
  • Dynamic Parameter Adjustment: Automatically optimizes laser frequency/power based on material hardness, improving sapphire drilling efficiency by 30%.


Typical Applications

Precision Mold & Bearing Manufacturing

  • Diamond Drawing Dies: Drilling holes <φ0.05mm to extend tool life by 30%.
  • Sapphire Bearings:
    • Micro-array drilling for spindle bearings with rotational accuracy ±1μm and enhanced wear resistance.
    • Sterile micro-drilling for medical implant bearings meeting biocompatibility standards.

Semiconductor & Electronics

  • Chip Packaging: BGA pad micro-via drilling with diameter consistency ±2μm.
  • Sensor Probes: Micro-hole formation in medical catheters with Ra≤0.1μm surface finish.

New Energy & Aerospace

  • Lithium-ion Battery Separators: Micro-porous arrays to increase energy density.
  • Titanium Alloy Blades: Cooling hole drilling without stress cracks associated with traditional methods.
