Laser Cut Holes

Laser cutting is a versatile and precise method for creating holes in various materials, ranging from metals to polymers. At A-Laser, we utilize advanced laser technologies to achieve high-precision cuts tailored to your specific requirements.

Can You Laser Cut Holes?

Absolutely. Laser cutting is renowned for its ability to produce clean, accurate holes with minimal material distortion. The process involves focusing a high-powered laser beam onto the material, which melts or vaporizes the targeted area, resulting in a precise cut. This contact-free method ensures that even delicate materials maintain their integrity during the cutting process.

What Size Hole Can a Laser Cut?

The size of the hole that can be laser cut depends on several factors, including the material type, thickness, and the specific laser technology employed. While the laser’s beam diameter plays a crucial role in determining the minimum achievable hole size, it’s important to note that the actual hole may be slightly larger due to material properties and the cutting process itself.

At A-Laser, our laser systems feature beam diameters as small as 20 micrometers (µm), enabling us to perform intricate cuts with exceptional precision. However, the minimum hole size achievable is influenced by factors such as material thickness and type. For instance, cutting a hole smaller than the material’s thickness can be challenging and may require specialized techniques. Therefore, while a 20 µm beam allows for fine detail, the practical minimum hole size will often be larger, accounting for the material’s response to the laser and the desired cut quality.

Factors Influencing Hole Size in Laser Cutting

1. Material Type and Thickness: Different materials react uniquely to laser cutting. Metals, for example, may require more laser power and can exhibit variations in cut quality based on their thickness. As a general guideline, achieving hole diameters smaller than the material thickness can be challenging. For example, cutting a 0.5 mm diameter hole in a 1.0 mm thick stainless steel sheet is feasible, but attempting to cut a 0.5 mm hole in a 5.0 mm thick sheet may not yield optimal results.
2. Laser Technology: The type of laser used—such as CO₂, Fiber, or UV—affects the precision and quality of the cut. UV lasers, for instance, can achieve tolerances as tight as ±0.0005 inches (0.013 mm) for certain metals, making them ideal for applications requiring high precision.
3. Heat Affected Zone (HAZ): The laser cutting process generates heat, which can affect the material surrounding the cut. Managing the HAZ is crucial, especially for materials sensitive to heat, to ensure the hole’s dimensions remain within the desired tolerances.
