• ​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%.
