Precision micro holes have the potential to make exciting new technologies possible. Many of these new technologies depend on high accuracy control of the fluid flow and spray patterns. For example, precise micro holes in fuel injectors enable auto engines to get more combustion from less fuel by creating more precise spray patterns. Micro holes in medical devices accelerate healing by precisely directing medication to targeted internal tissue. But traditional CNC machines have not been able to reach the specifications of these breakthrough designs. They are too coarse, requiring multiple post processing steps to deliver accurate parts, and too slow to be cost-effective.
Microlution has developed a turnkey ultrafast precision micro hole drilling solution that incorporates a leading edge industrial grade femtosecond laser capable of athermal, or heatless machining into the high speed, ultra precise Microlution ML-5 micro milling platform. Femtosecond laser heatless machining enables new levels of precision by eliminating heat affected zone (HAZ) and any other thermal damage to the part, leaving a near perfect hole in a single step. Also, because lasers do not erode over time like mechanical tools, the solution delivers unprecedented consistency and repeatability in a factory environment.
Critical to achieving ultrafast precision micro drilling is the ML-5’s ultra precise part loading, holding, moving, and measuring capability. This, combined with femtosecond laser precision enables the Microlution micro hole solution to achieve positional accuracy within 1 micron, and to machine feature sizes from 50 to 500 microns, with a 10:1 aspect ratio for the depth of the hole. The integrated femtosecond laser can process virtually any material – metals, plastics, and glass – with unrivaled surface quality and edge quality since there is no burring, recast, or other thermal defects. The ML-5 motion platform can deliver extremely fast cycle times (< 10 sec.) to make the solution cost-effective for most applications. The result is a turnkey micro hole drilling solution that is high speed, ultra precise, and delivers higher quality parts with higher yields.
