Mazak Laser, the Story so Far

The last three years have seen significant change in Mazak’s laser business across Europe, not least the decision to combine the division with machine tools. We meet Gaetano Lo Guzzo, Director Mazak Laser Europe, to find out more.

Micro Processing

Functional Surfaces by Laser Interference

Today, various laser processes are used in industrial applications to ablate, clean and pre‐treat surfaces for contacting, coating or bonding. Usually, layers with a thickness of several hundred micrometers are removed, or microscopic changes are made to the surfaces for improved bonding properties of paints or adhesives. Entirely new areas of application can be accessed by innovative methods for creating much smaller…

Additive Manufacturing

From Lab to Fab — High‐Precision 3D Printing

The demand of sophisticated components is continuously increasing, driven by big data, IoT, and Industry 4.0. Reducing process cost is impacting all levels in a vast majority of products. 3D printing is typically restricted to additive fabrication within one material class, structures are limited in size, shape, surface finish, requiring supporting structures. This prevents high quality photonic components. High precision…

Micro Processing

Femtosecond Laser Micro Milling Using Special Trepanning Optics

Micromachining methods like electrical discharge machining (micro‐EDM), chemical etching, mechanical micro milling or thermal laser machining, are limited by material properties like chemical reactivity, optical absorption, electrical conductivity, and melting point. Also, the demand for a wall steepness of 90°, a feature size of < 100 μm, radius of curvature < 20 μm, or the required process speed limit the choice of…

Materials Processing

Hard Outside and Soft Inside

As to complex component geometries and components subject to wear — for which conventional hardening techniques often fail —, the laser‐beam hardening process nowadays offers new solutions to create wear‐resistant surfaces. In particular, curved and surfaces that are difficult to access, holes as well as components that easily warp can be efficiently hardened by means of laser. The challenges and solutions for series…

3D‐Printed End‐of‐Arm for Smarter Packaging

New robots for the pick‐n‐pack line were already on order. A major American food producer’s equipment supplier, the Langen Group, began designing the end‐of‐arm tool that would enable the robots to pick up wrapped, stacked crackers and place them into cardboard boxes. Then the engineers ran into a challenge.

Application Report

Laser Marking of Small Manufacturing Lots at High Throughput

Laser labeling and marking of metal serial parts is a well established technology in industrial manufacturing. From part or serial numbers to Data‐Matrix codes or logos, such data can be applied to parts permanently, quickly, and cost efficient. However, there are several ways to integrate laser labeling into manufacturing processes depending on volumes, production process, and desired degree of automation. Laser labeling…

Application Feature

Bringing the Laser to the Product

Highly agile, self‐organizing industrial 4.0 production environments require an extremely high level of intelligence and networking of all process relevant factors. Not to be underestimated in this context is the integration of laser marking systems, which ensure a safe, durable marking, and therefore a definite traceability of the produced parts or products. Optical part recognition and individual laser marking as part of…
