Pico-precision Laser Drilling Machine for Sapphire bearing processing

Product Overview


The equipment combines ultra-fast picosecond laser technology with intelligent control systems, designed for high-value material precision processing. Key advantages include:

  • ​Picosecond-level Ultra-fast Processing: 1064nm wavelength pulsed laser with energy levels adjustable from 0.1mJ to 5mJ (step size 0.1mJ), delivering pulse durations <10^-12 seconds. This minimizes thermal damage (<10μm heat-affected zone) and eliminates micro-cracking.
  • ​Full Digital Closed-loop Control: Equipped with industrial-grade PCs and proprietary ​LaserMaster Pro​ software, supporting G-code programming, CAD auto-conversion, and real-time path optimization. Positioning accuracy reaches ±0.005mm.
  • 4-Axis Intelligent System: XYZ axes with ±0.002mm repeatability and optional C-axis rotation enable complex multi-tasking for irregular hole patterns.

Typical Applications:

  • Semiconductor industry: Wafer drilling, micro-structure fabrication
  • Ultra-hard materials: Diamond tooling,apphire optical component micro-drilling
  • Biomedical field: Artificial joints, dental implants precision drilling
  • New energy sector: Lithium-ion battery micro-porous array processing

Processing Performance & Quality Assurance


1. Exceptional Processing Capabilities

  • Micro-drilling: Minimum aperture φ0.5μm, depth-to-diameter ratio up to 1:50 (no chipping in hard materials)
  • Complex Structures: Supports conical holes (0.1°–5° adjustable), spiral grooves, and multi-stage holes in one process
  • Non-destructive Cutting: Ideal for thin films (e.g., PI film, graphene) with sub-micron precision

2. End-to-End Quality Management

  • Smart Compensation: Real-time monitoring of laser power fluctuations and thermal deformation with dynamic parameter adjustments
  • Process Database: Pre-built parameters for over 200 materials (metals, ceramics, gemstones, composites)
  • In-line Inspection: Automated generation of hole size distribution maps and surface roughness analysis reports (Ra ≤0.8μm)

3. Material Compatibility Test Results
