Magazine for laser technology and surface processes.

The articles here address the questions that actually come up before an investment. How a process works physically and why the wattage alone says little. How to tell whether a material is suitable for a particular kind of processing. What part extraction, risk assessment and protective measures play in day-to-day operation. And when buying, hiring or a commissioned service is the more cost-effective decision.

Two kinds of text about laser technology circulate online: manufacturer brochures that keep quiet about every limitation, and forum posts that turn a single case into a rule. Neither is of much help to a business preparing an investment decision or wanting to replace an existing work step. We aim for the middle ground: sound fundamentals, named sources and an explicit note wherever a statement depends on the individual case.

A recurring pattern is therefore the separation between what is technically possible and what pays for itself. A process can solve a task excellently and still be too slow for series production. Conversely, an apparently weaker system can do exactly the job it is needed for. This distinction runs through almost every article, because in practice it is the most common source of error in the selection.

We write deliberately with restraint. Laser technology can do a great deal, but not everything, and it is not the fastest or cheapest means in every case. Where another process is the better choice, the text says so. We do not explain technical terms twice but refer to the glossary with 160 technical terms, which defines every expression in one place.

They are aimed at businesses that machine, maintain or further process metal: production, maintenance, tool and mould making, metalworking, restoration and service providers that carry out surface processes for third parties. We do not assume prior knowledge of laser technology. Where a technical term appears for the first time, a link leads to the glossary instead of interrupting the flow of the text with a definition.

The articles are no substitute for a test on the actual component. They are meant to sharpen the questions a business takes into such a conversation — and to name the key figures that matter in it. Which surface processes are suitable for a task is decided by the material, the layer and the required final condition, not by a number on a data sheet.

For specific applications it is worth looking at the overview of application areas; for machine classes and performance data, the page on the available machines. Anyone with a task that an article cannot answer can describe it directly and have a component tested — the real workpiece shows what is achievable faster than any table.
