When you need just-in-time manufacturing, laser technology is the ideal converting solution. Machines with this capability increase the accuracy of your overall production by ensuring clean lines and precise detailing on your finished products. You may want to consider laser cutting if you are currently converting components from the following materials:
Laser cutting directs the output of a high-power laser through optics to cut and engrave materials into programmable designs and dimensions. Precision laser cutting can be used to produce through holes, slots, and diameters that are significantly smaller (and at tighter tolerances) than results generated by other converting processes. It is a dieless process, meaning no hard tools are needed, eliminating expensive and time-consuming die costs.
As it makes its way across the material, the laser vaporizes material in the beam path, leaving an edge with a high-quality surface finish, eliminating the need for complex extraction methods to remove scrap and smaller pieces usually left behind by other cutting machine. This method of material modification allows you to quickly change designs while also improving the quality of finished parts.
Ablation of Material – Material ablation is a process that virtually removes the material completely from the top to the bottom of the surface or partially from the top of the material to a pre-set specified depth.
Laser Die Cutting – Laser die cutting is the complete removal and separation of the material from the top surface to the bottom surface along a designated path generated by the CNC or G-Code of the pattern to be cut. Laser die cutting can also include processes like kiss-cutting, slitting, perforation, through-cuts and/or slug removal.
Laser Engraving – Laser engraving is the process by which material is removed from the top surface down to a specified depth. By continuously varying the laser power, laser engraving can be used for textures, images, bar-codes, text and numbers.
Laser Marking – Laser marking, which is essentially engraving the material, is a broader category of methods to leave marks on an object to produce a readable identification or information such as a barcode, lot code, serial number or a part number. This technique does not involve the use of inks, nor does it involve tooling which contact the engraving surface & eventually wear out, giving it a significant advantage over alternative engraving or marking technologies where inks or tools have to replaced regularly.
Combined Processes – Digital laser processing is a proven, viable solution for processing a wide variety of materials. The multiple processes referenced above can be combined to total cut, kiss-cut and engrave or mark various substrates in roll or sheet form in both continuous, start-stop and tracking models.
The Guidolin Girotto RO Series galvanometer laser cutting systems have revolutionized the way converters and application specialists conduct their manufacturing processes. A Galvanometer Laser is typically used for cutting thinner substrates, less than 3mm in thickness. The laser beam is delivered by two rotating mirrors instead of a gantry system, allowing the galvanometer laser to function at a level ten times faster than a flatbed laser. Here are a few models to keep in mind if you want an extra boost in your production and product quality.
RO 175 EL – The RO EL Series is a cost-effective, entry level laser die cutting solution. With a 175mm working width, this machine is engineered to handle anything from labels, to adhesive tapes, double sided adhesives, VHB tape, textiles, paper, foam, rubber, silicone, PU, PE, PET, polycarbonates, polyethylene, polypropylene, abrasives and similar products.

RO 250 – The RO 250 model has a useful working width of 250mm and is the ideal solution for converters that demand versatility, combining our traditional RO series rotary converting platform with a laser cutting module. The machine’s combination of functionality allows for new systems to be installed on the machine without modifying the original set-up—expanding your overall variety of solutions.
RO 350 – The RO 350 series is a highly-efficient CO2 “Self-Refilling” laser source, ideal for applications on adhesives, plastics, graphics, overlays, labels and similar materials. It offers the most flexibility and production throughput for materials up to 350mm in width. Depending on the application, the speeds of the RO 350 can reach up to 100 Mts/Min.
In modern manufacturing, choosing the right cutting technology is crucial for efficiency, quality and cost-effectiveness. Laser cutting, CNC milling and waterjet cutting are three established processes that each offer their own advantages. This article highlights the particular advantages of laser cutting compared to the traditional cutting techniques of CNC milling and waterjet cutting and shows why laser cutting has proven to be superior in many areas.
Laser cutting is a non-contact process in which a focused laser beam is used to cut materials with high precision. The laser beam is strongly bundled by a focusing lens, which melts, vaporizes or burns material at the cutting point. Typical materials that are processed with laser cutters are metal, wood, acrylic, textiles and many more.
One of the most outstanding advantages of laser cutting is its exceptional precision. The laser beam can cut fine details and complex geometries that are difficult or impossible to achieve with traditional techniques. This is particularly important in applications that require the highest accuracy, such as in electronics or medical technology. While CNC milling can also be precise, it is often less flexible when it comes to processing complex shapes. With waterjet cutting, certain materials can be slightly blurred, which is avoided with laser cutting.
Laser cutting offers a remarkable cutting speed that is often higher than traditional techniques. This leads to a significant increase in productivity and a reduction in processing times. While waterjet cutting is also precise, it is often slower, especially with thicker materials. CNC milling requires more time and careful programming for complex geometries and fine details.
Laser cutting can process a wide range of materials and material thicknesses, from metals and plastics to wood and composites. This versatility makes it an attractive choice for various industries. CNC milling and waterjet cutting are also versatile, but often limited by the type of tools and water consumption.
While laser cutting is particularly efficient for thin and medium-thick materials, waterjet cutting can offer advantages for very thick materials. CNC milling, on the other hand, can also be effective with thick and hard materials, but often requires longer processing times. Laser cutting can also process thick materials with high precision, but its efficiency depends heavily on the power of the laser.
Laser cutting is often more energy efficient and produces less waste compared to traditional techniques. It does not require additional tools that wear out and need to be replaced, as is the case with CNC milling. Waterjet cutting consumes large amounts of water and abrasives, which can cause additional costs and environmental impact. However, the operating costs of a laser cutter can vary depending on the application and material.
Laser cutting offers a number of advantages over traditional cutting techniques such as CNC milling and waterjet cutting, including greater precision, faster processing times, greater versatility and reduced environmental impact. These advantages make it a preferred method in many industrial applications and contribute to the efficiency and quality of manufacturing processes. Companies that invest in modern laser cutting technology can benefit significantly from these advantages and improve their competitiveness in an increasingly demanding market.
