Laser drilling
Smallest drilling in metallic and ceramic materials
High-temperature resistant materials such as Hastelloy, tungsten, molybdenum and all types of precious and non-ferrous metals are suitable for laser drilling. Ceramic materials such as sapphire, ruby, diamond or aluminum oxide and related materials can also be drilled with the laser.
With single-pulse drilling, a single laser pulse with comparatively high pulse energy generates the hole. In this way, many holes can be produced very quickly. This process is often used to produce filters with thin walls up to approx. 1 mm thick.
In percussion drilling, the hole is created by several successive laser pulses with a shorter pulse duration and pulse energy. This drilling method produces deeper and more precise holes than single-pulse drilling. Percussion drilling enables hole diameters of 0.02 to 0.4 mm and drilling depths of up to 10 mm.
