Ultrafast Laser Micro Machining
Our femtosecond laser platforms support advanced machining operations well beyond the capability of conventional drilling technology. We excel at small features, drilling holes as small as one thousandth of an inch in diameter. Holes can be cylindrical, elliptical, positive or negative taper.
To avoid the problem of overheating materials (which would require time-consuming secondary processing), the rms platform uses an ultrafast pulse. That essentially creates a fast and efficient athermal process to avoid material damage.
Laser Features
- 5-axis motion control and 5-axis laser control
- Straight, tapered, and reverse tapered holes down to Ø.001”
- 7:1 Feature aspect ratio
- True athermal ablation with no heat affected zone
- Positional accuracy: ±.00004” (1 Micron)
- Typical diameter tolerances: ±.0004” or less
- Surface quality of inner wall: Ra < 0.1 Micron
- Maximum stock size: 8.25”x4.7”x5.9” (3 Axis) or Ø2.9”x5.9” (5-axis)
Accelerating production with advanced technology, like the femtosecond laser, saves customers time and money.
