Micro drilling processing | Achievements of 5μm diameter - Femtosecond laser
Femtosecond laser micro-hole processing
From prototype one, with minimized thermal impact, we create fine holes in nozzles, filters, and precision parts. Compatible with metal, glass, and resin.
Using femtosecond lasers, we process fine holes and cut shapes in metals, hard alloys, glass, ceramics, and resins. Since the processing is completed before heat is transferred to the surroundings, we can achieve drilling with minimal melting, burrs, and cracking. We have successfully created holes with a diameter of 5μm in SUS304 (thickness 0.1mm), as well as honeycomb shapes with a cell size of 0.18mm and a remaining width of 12μm (0.012mm). We can accommodate not only round holes but also irregular holes, slits, and cut shapes. Due to the characteristics of the laser, there is a difference in diameter (taper) between the entrance and exit of the hole. For areas requiring precision, we recommend a combination with electrical discharge machining or 5-axis machining.

We will provide a quote individually based on hole diameter, number of holes, material, and plate thickness. Estimates are free.
Delivery Time
※We will proceed to the main processing after confirming the hole diameter and taper with test machining.
Applications/Examples of results
【Achievements】Holes with a diameter of 5μm in SUS304 (thickness 0.1mm) / Honeycomb (cell 0.18mm, remaining width 12μm (0.012mm)) / Drilling holes in the tens of μm range in glass / Fine cutouts in wood (approximately 1mm per character). 【Applications】Nozzles, orifices, filters, pinholes, fine holes in precision parts, prototypes for research and development. 【Guidelines for Methods (General)**】Femtosecond lasers typically range from a few μm to several hundred μm, while CO2 lasers range from several hundred μm to several mm. We will propose the optimal method based on shape and quantity.
