Laser Cutting

2025-12-09

Unlike traditional cutting technologies, femtosecond laser cutting minimizes mechanical stress, reduces tool wear, and ensures clean, burr-free cutting edges. The cold ablation technology used in femtosecond laser cutting minimizes thermal effects, thereby avoiding material deformation, cracking, and heat-related damage. Femtosecond lasers ensure materials absorb energy only at the exact moment and location required—no excess heat, no collateral damage.

This femtosecond laser cutting method is ideal for delicate materials or thin foils. It has flexible cutting trajectories, enabling various shapes like circles, straight lines and even complex patterns, offering multiple possibilities for precise material removal.

The terms "drilling" and "cutting" are not always clearly defined. For example, a hole made by the spiral cutting process is called drilling, but it is actually formed by layer-by-layer cutting.

Advantages of Femtosecond Laser Micro Cutting

•Perfect cutting edges

•No melting, no burrs, no microcracks

•Material freedom

•Precise cutting of any super-hard, ultra-thin, heat-sensitive materials

•Micron-level precise reproduction

•Transforming complex designs into perfect miniaturized components

Metal Foil Cutting

Leveraging its flexible cutting trajectories, we provide metal foil cutting services for precision parts like semiconductor electronics and optical instruments. The cut parts feature irregular shapes, smooth sidewalls, and minimal thermal impact, with precise angle control and customized processing parameters available as required.

Precision Cuts with Vertical Cutting Edges

In some high-end scenarios, parts need high compatibility to boost product performance, often requiring specific cutting tapers. For example, zero taper is required when manufacturing micron slits in mass spectrometers, which significantly increases throughput without sacrificing resolution.

Non-Metal Material Cutting

Femtosecond lasers are unique in minimizing thermal effects while maintaining sub-micron feature sizes, delivering exceptional quality and precision. They’re the perfect choice when other laser or mechanical methods can’t meet technical and quality requirements for high molecular polymers and composite materials.
