Lasertrimmen

Lasertrimmen is a manufacturing process used to precisely remove excess material from a component using a laser beam. This technique is particularly valuable for applications where high accuracy and minimal material distortion are crucial. The laser's focused energy ablates, vaporizes, or melts away small amounts of material, allowing for fine adjustments to shape, size, or surface characteristics.

The process typically involves a high-power laser, such as a CO2 or fiber laser, directed at the workpiece. The laser beam is often controlled by a computer numerical control (CNC) system, which guides the laser along a predetermined path. This enables intricate trimming operations that would be difficult or impossible with conventional methods. Lasertrimmen can be applied to a wide range of materials, including metals, plastics, ceramics, and composites.

Key advantages of lasertrimmen include its non-contact nature, which prevents mechanical stress and contamination of the workpiece. It also offers high speed, precision, and repeatability. The process is often used in industries like electronics, where delicate components require precise trimming, and in the automotive sector for shaping and finishing parts. For instance, it can be employed to trim thin films on semiconductor wafers, adjust the dimensions of plastic injection molded parts, or refine the edges of aerospace components. The specific laser parameters, such as power, pulse duration, and beam diameter, are carefully selected based on the material properties and the desired outcome of the trimming operation.
