Cost is No Longer a Show Stopper for Fiber Laser Cutting
There is significant competition in the market between different cutting technologies, whether they are intended for sheet metal, tubes or profiles. There are those that use methods of mechanical cutting by abrasion and others that prefer thermal methods.
However, with recent breakthroughs in technology and with cost per diode dropping exponentially, fiber laser cutting is replacing high-definition plasma, CO2 laser, and other thermal cutting techniques for many applications. Fiber Laser was once considered too expensive even though it could do the job best. Now that it is more economical, the decision criteria should be focused on accuracy, thickness, geometry and material requirements. Here are some cutting technologies that offer value based on these requirements.
Water Jet
This is a valuable technology for all those materials that might be affected by heat when performing cold cutting, such as plastics, coatings, or cement panels. To increase the power of the cut, an abrasive material may be used that is suitable for working with steel measuring greater than 300 mm. It can be very useful in this manner for hard materials such as ceramics, stone or glass.
Punch
Although laser has gained popularity over punching machines for certain types of cuts, there is still a place for punch due to the fact that the cost of the machine is much lower, as well as its speed and its ability to perform form tool and tapping operations that are not possible with laser technology.
Oxycut
This technology is the most suitable for carbon steel of greater thicknesses (75mm). However, it is not effective for stainless steel and aluminum. It offers a high degree of portability, since it does not require a special electrical connection, and initial investment is low.
Plasma
High-definition plasma is close to laser in quality for greater thicknesses. Traditionally, it has enjoyed a lower purchase cost that offsets the expensive operational costs versus the fiber laser which has traditionally had a much higher purchase cost and very low operational costs. Unlike fiber laser, plasma often requires post-cut machining/grinding to clean up the part and that contributes to a higher operational cost. Now that fiber laser purchase prices are dropping, the Total Cost of Ownership (TCO) for Fiber Laser can be less than Plasma. Even so, Plasma is the most suitable from 5mm, and is practically unbeatable from 30mm, where the laser is not able to reach, with the capacity to reach up to 90mm in thickness in carbon steel, and 160mm in stainless steel. Without a doubt, it is a good option for bevel cutting. It can be used with ferrous and non-ferrous, as well as oxidized, painted, or grid materials.
CO2 Laser
Generally speaking, the laser offers a more precise cutting capability. This is especially the case with lesser thicknesses and when machining small holes. CO2 is suitable for thicknesses between 5mm and 30mm. It does have a lot of consumables and energy that makes its operational cost higher than fiber laser.
Fiber Laser
Fiber laser technology is quickly gaining popularity due to its speed and quality that rivals traditional CO2 laser cutting. It is also more cost-effective and energy-efficient, resulting in lower investment, maintenance, and operation costs. As the price of fiber laser machines continues to decrease, it becomes an increasingly attractive option compared to plasma & certainly CO2 laser cutting. Additionally, fiber laser technology also performs better with reflective materials such as copper and brass. In summary, fiber laser technology is emerging as a top choice for manufacturers due to its performance, cost-effectiveness (TCO), and ecological benefits.
While there may be instances where only one specific cutting technology is suitable for a particular part, fiber laser technology is now more accessible and applicable to a wider range of applications due to its decreasing cost. When considering fiber laser technology, cost is no longer the major factor why manufacturers object. Instead, factors such as the material, thickness, desired quality, and internal hole diameters should be taken into account when deciding on the right cutting solution. It is important to analyze the physical and geometric properties of the part to determine the most suitable machine for its production. Fiber laser is proving to be the cutting solution of choice for the stricter cutting requirements in today’s products.
Primary Industries that Rely on Fiber and CO2 Laser Cutting
Laser cutting is a popular method for cutting materials such as metal, plastic, wood, and glass. It is used in a variety of industries, including the automotive and medical device industries, due to its high accuracy and precision. Each industry has its own requirements and uses laser cutting in different ways. For example, the automotive industry uses laser cutting to create car parts and components while the medical device industry uses it to create medical devices and implants.
Automotive Industry: The automotive industry uses laser cutting to produce a range of components with tight tolerances. Laser cutting’s flexibility and ability to create complex shapes make it a popular technology for producing car parts. In the past, car parts were created with stamping and die-cutting methods, but these methods are not as accurate or capable of creating complex shapes as laser cutting. Sheet metal laser cutters are commonly used in the automotive industry to cut materials such as car parts, components, die-castings, forgings, and stampings. Laser is a often used to trim parts of excess material after stamping too and this reduces machining time.
Metalworking Industry: Metalworking involves shaping and forming metal into desired shapes using various tools. Laser cutting is often used in the metalworking industry to cut metal into desired shapes for products such as beams, columns, pipes, tubing, and sheet metal. These products can be used in industries such as construction, automotive, and aerospace.
Medical Device Industry: The medical device industry uses laser cutting to produce products such as pacemakers, stents, and catheters. The laser beam melts, vaporizes or burns away material to leave a clean, precise cut. Laser cutting is often used to create intricate designs for products intended for use within the human body. The type of laser cutting used depends on the material being cut and the desired final product. For example, stainless steel can be cut with a CO2 laser while plastics can be cut with a fiber laser.
Jewelry Industry: The jewelry industry has undergone a major transformation with the advent of laser-cutting technology. While traditional methods relied on manual labor and simple tools, laser cutting allows for more precise and intricate designs. As a result, jewelry made with laser cutting is often more intricate than its traditional counterpart. Laser cutting is typically used in the jewelry industry to create detailed patterns in metal and to cut gemstones. It can also be used to engrave text or images onto jewelry pieces. Common jewelry products made with laser cutting include rings, pendants, earrings, and bracelets. The use of laser cutting in the jewelry industry has revolutionized jewelry making and allowed for new levels of creativity and design.
Ceramic Manufacturing: Ceramic manufacturing involves shaping and firing ceramic materials to create products. Laser cutting can be used to create precise shapes and designs in ceramics. This is often used to create intricate patterns and decorative elements in products such as tiles, pottery, and sculptures. CO2 laser cutting is typically used in the ceramic industry to cut through the material with precision and speed.
Silicon Industry: Laser cutting is a vital process in the silicon industry, which produces silicon wafers for use in electronic devices. CO2 laser cutting is used to create small-scale features on silicon wafers for products such as integrated circuits, solar cells, and semiconductor chips.
Packaging Industry: Laser cutting is used in the packaging industry to create products such as boxes, containers, and lids. Both fiber lasers and CO2 lasers are used in this industry. CO2 lasers are typically used to cut cardboard, paper, and thin plastics while fiber lasers are used to cut thicker and harder packaging materials.
Woodworking Industry: The woodworking industry produces wood products for construction, furniture making, and other purposes. Laser cutting is often used in this industry to create precise and intricate designs in wood for products such as furniture, cabinets, and decorative items. CO2 laser cutting is typically used in the woodworking industry to cut through wood with a high level of precision.
