The advantages of the fiber laser cutting
Laser cutting has been advantageous compared to other traditional cutting forms since it has been introduced. On mild steel, stainless steel, and aluminum the laser cutting process is highly accurate, provides excellent cut quality, has a very small kerf, (width of the cut or groove) has a small heat affect zone, and makes it possible to cut very detailed shapes and small holes or lines. Learn about more of the advantages of laser cutting below.
CLEAN CUT EDGES
The precision levels and edge quality achieved with laser cutting are much better than traditional cutting methods, as a laser beam will not wear during the cutting process. You can look at a laser beam as a very small cutting tool. Because the laser utilizes a much more focused spot, less heat is put into the sheet metal and removes a narrower path of material. This is also known as the heat affect zone. This allows the laser to cut more precise parts to a higher tolerance and with cleaner edges
This means that the laser beam used in laser cutting doesn’t physically touch the material that it is working with, instead causing the melting and cutting process through heat. This means that damage to the material is minimised and costly repair and maintenance schedules for moving parts that contact the work surface can be avoided.
The highly accurate and precise nature of laser cutting is one of the greatest benefits that it has brought. It allows for highly accurate cuts that leave a clean cut and a smooth finish. This has helped products, components and devices to become much smaller, and vastly reduces the amount of material wastage that has been seen in the past.
Due to the high processing speeds of a laser, resulting in a small heat affect zone, and contactless material processing, there is minimal workpiece distortion or warping that comes with laser cutting. This in return gives you a high quality sheet metal product.
Low operation COSTS
Laser cutting does not require any hard tooling as a punch press or shear does. It is a very "lean" manufacturing method eliminating the need for tool changeover, tool storage and tool sharpening maintenance. Because no hard-tooling is required, laser technology enables us to cut detailed shapes at similar or faster speeds than other cutting methods.
MATERIAL SCRAP SAVINGS
Due to a cutting tool needing material on either side of a cut, a border of a 1/2" or sometimes more is required, resulting in scrap. For a laser, if parts share a common cutting line, they can be cut with single cut, which reduces scrap. Cutting techniques like nesting, lead-ins and lead-outs and tabbing on a laser are some other ways to save scrap while utilizing this process.
