little or no tooling cost, repeatable, accurate
holes, and rapid set up time laser drilling is the
production method of choice for R&D, short run
production, and long run production runs.
Directed
Light specializes in high speed, high precision
laser drilling of metals and non-metals. Holes
from 25 µm to 150 µm diameter can
be percussion drilled and holes from 50 µm
diameter and larger can be trepanned. While percussion
drilling is faster, better roundness is obtained
by trepanning.
All of our laser drilling
systems have 2 or 3-axis liner motor motion systems
with CNC control and .1 µm resolution. Many
of our systems also have an integrated rotary
axis. With CO2 systems ranging from 150W to 1kW,
Pulsed Nd:YAG drilling systems and 1064 ?m and
532 ?m Q-Switch Nd:YAG drilling systems we can
drill your parts from tubes or sheets in any of
the following materials:
- Carbon Steel
- Nickel
- Aluminum
- Brass
- Gold
- Silicon wafers
- Aluminum Nitride
- Acrylic
|
- Stainless Steel
- Titanium
- Nitinol
- Copper
- Molybdenum Rhenium
- Alumina
- Polyimide
- Polycarbonate
|
Design Considerations for Laser Drilling:
 |
The aspect ratio
= L/D and the acceptable taper are considerations
for laser drilling. Because the laser
beam is a focused cone
there will be some taper to drilled
holes. This taper depends on the focal
length of the lens and the thickness
of the material being drilled.
DLI selects the proper
laser system and optics depending
on your requirements. A general rule
of thumb is that the taper will be
2.5% of the thickness of the material. |
