Laser Marking - KEYENCE America
6 days ago · Laser Marking on Metal. Laser marking can be performed on metal through black-annealed marking, where the laser causes oxidation; white marking, where the laser is used to scrape away the target surface; and engraving, where the laser is used to carve deep into the target surface. Each method is used for a specific purpose.
Laser Marking Systems / Laser Markers | KEYENCE America
Laser markers vary by the wavelength of light, and different wavelengths are optimized for marking and processing different materials. The majority of industrial laser markers are YVO 4 lasers, fiber lasers, UV lasers, and CO 2 lasers. Laser markers are used to permanently mark text, logos, barcodes, or 2D codes on parts in all industries.
UV Laser Marking - KEYENCE America
2 days ago · The 3-Axis UV laser markers use a UV wavelength of 355 nm to mark or process parts with cold-marking technology. These markers have three different axes to control the laser beam, designed for uniform marking over large fields of view or 3D shape parts. UV laser marker systems incorporate groundbreaking technology that is revolutionizing the ...
The 3 Most Common Types of Laser Marking | KEYENCE America
Laser engraving is a method of marking where a focused laser beam carves a design into a material’s surface. The indented marks are created by evaporating the surface. Four types of lasers are used for engraving: UV, fiber, CO 2, and hybrid. Each of the different types of laser engravers is ideal for different materials, products, and industries.
3-Axis Hybrid Laser Marker - MD-X series | KEYENCE America
Mark the same location on any part, anywhere. The MD-X Series contains a camera inside the laser marking head which can automatically identify a target’s shape. The laser marker can then adjust for X, Y and theta offsets to ensure the marking position is always correct. The marking system is even able to distinguish between parts and mark ...
Laser Etching: A Complete Guide - KEYENCE America
Laser etching is a no-contact marking method that creates raised or engraved marks (as deeply or shallowly as desired) on a target. These marks are used for traceability, aesthetics, logos, designs, or adhesion. Laser etching uses a laser beam that …
Guide to Understanding Laser Powers | KEYENCE America
The laser power affects weld strength, cutting speed, marking contrast, engraving depth, heat-affected zone, etc. For instance, a laser marker used for precise engraving on delicate materials may operate at a much lower power than one used for cutting thick metal sheets. Similarly, higher laser powers are typically required for welding thicker ...
Understanding Laser Classes & Laser Safety | KEYENCE America
KEYENCE’s laser marking machines are Class 4 lasers because of their wavelength and ability to process materials. Although they are Class 4, there are protocols that can establish the laser as Class 1 following the right enclosure or equipment practices, and the KEYENCE support team can help guide you in the right direction.
CO₂ Laser Marking - KEYENCE America
This enables precise marking on 3D part shapes and reduces tooling costs. The ML-Z CO 2 laser uses the 3-axis control to mark uniformly across step, inclined, cylinder, and circular cone targets. It can even use CAD data of non-standard shapes to map its focal path and retain focus. 300 mm (11.81″) wide area.
Laser Labeling and Marking Systems | KEYENCE America
Laser labeling is the process of using a laser marking machine to put a label on a product. The label can be used for traceability, identification, or adding regulatory information. Replacing a labeler with a laser can have benefits across many aspects of production. Using a laser marking machine rather than a standard inkjet printer for ...
