Industrial Laser Micromachining Small Geometries – High Dynamic – Debris Protection Machining workpieces for generating tiny geometries in the micron range demands automation platforms that provide a consistent, accurate and dynamic processing in multiple dimensions. As the size and mass of the manufactured parts may be challenging and particles may be formed during machining, the system components used need to be highly precise, stiff, robust and offer reliable performance. Vertical Axis – Laser Positioning Reference edge to support the alignment in the machine Ability to run directly on 110/240...

Laser Cutting High Precision – High Dynamic – Long Travel Ranges Laser applications such as those for producing stencils or processing printed circuit boards and flat panels set high requirements to automation platforms: The dimensions and mass of the workpieces, and the structural density are typically large in comparison. To achieve micron precision and high throughput, the system has to offer long travel ranges with a high stiffness but light weight motion platform. This allows the laser head or galvanometer scanner to be moved at high speed precisely over the part. Vertical Axis – Laser Positioning...

Extra Large Field Marking High Precision – High Throughput – Simultaneous 2D Processing Processing high density structures over large areas such as hole drilling, or glass and foil marking requires automation solutions which provide high precision and high velocities. A possibility to address the needs of industrial production is the coordination of multi-axis positioning systems with a high dynamic galvanometer scanner. Typically the stages move the workpiece to the center of the field of view of the scan head and signal that the scanning process can be started. Once this operation is completed,...
