With the rapid advancement of technology, materials used in small-hole machining continue to diversify, while hole diameters become smaller and quality requirements more demanding. Laser drilling, with its advantages of high precision, flexibility, efficiency, and cost-effectiveness, has become a key technology in modern manufacturing.
Currently, laser drilling is widely applied in aerospace, automotive, electronics, and chemical industries. For example, a Swiss company uses solid-state lasers to drill micro-holes in aircraft turbine blades, achieving diameters of 20–80 μm with depth-to-diameter ratios up to 1:80. Laser processing can also produce various micro-scale irregular holes-such as blind holes and square holes-in brittle materials like ceramics.
Since the mid-to-late 1980s, countries such as the United States and Germany have applied laser technology to large-scale deep micro-hole machining in industries like aircraft manufacturing. In 1984, an American aircraft engine manufacturer used lasers to process tens of thousands of cooling holes in turbine components. In 1986, the Kyiv Polytechnic Institute in the former Soviet Union applied industrial lasers to drill center holes with diameters of 0.6–1.0 mm and depths up to 6 mm in cemented carbide materials.
Entering the 1990s, laser processing technology continued to advance globally, with developments toward higher speed, greater flexibility, and smaller hole diameters. In Japan, micro-holes of 0.2 mm were drilled in 1 mm thick silicon nitride plates, and holes as small as 0.02 mm were achieved in 0.05 mm ceramic films.
Today, ceramic micro-hole machining is a key focus in precision and micro-processing technologies. Its development plays an important role in advancing electronic ceramic components. In the electronics industry, traditional high-speed micro-drills often struggle to process holes smaller than 0.25 mm in ceramic substrates. In comparison, YCLaser's high-precision laser cutting machine can achieve micro-hole machining down to 0.05 mm(depending on material type and thickness)
During ceramic micro-hole processing, Yclaser focuses on improving hole quality while minimizing taper and surface cracking. Welcome to provide your samples for testing and process evaluation.
