Laser Cutting

Laser Cutting

Utilizing advanced technological machinery and equipment in industrial areas has many advantages over production processes. One of the indispensable solutions is to get support from technology, especially in areas where it is impossible to operate with human power or, if it is done, time loss is experienced. Laser cutting is one of the technologies that serve this purpose.

It becomes easier to obtain a fast and desired product output in the cutting and forming processes of hard metals such as stainless steel, sheet metal, and aluminum. It is a technology based on the principle of directing laser beams with powerful and precise cutting feature with optical glasses. It is possible to produce laser beams with the support of lamps compatible with the target.

With its sensitive and powerful cutting feature, it is easier to give the desired shape to materials that are difficult to bend with human power, such as steel and metal. Laser cutting machines, which can work precisely with pre-loadable cutting codes, offer perfect cutting. In addition, with pre-loadable codes, various motifs and ornaments on the material become possible thanks to this cutting method.

Laser beams consist of light columns with a single wavelength and high intensity. Since this wave is red-red in the light spectrum, it is not visible to the human eye. It is produced in a closed environment on a CNC machine. In this production mechanism, electrical resonances have an essential role in the formation of rays.

Laser Cutting Machine

Laser cutting is used in almost every field. For this reason, it is possible to come across cnc laser technologies in many areas. The device’s speed, which is suitable for various materials, is another point that increases its preferability. In this respect, it is among the inevitable equipment of the production process in many sectors from decoration to textile.

Devices that enable cutting with laser beams are suitable for processing surfaces with almost any hardness, especially metals. In addition, it is one of the most important features that it does not have any margin of error in this process or makes cutting with tiny margin of error. With the engraving process, it may be possible to sign different figures in terms of design.

There are five different parts in laser machines:

  1. Laser source
  2. Moving motors
  3. Control card
  4. Machine body
  5. Power supply, cooling and vacuum

Working Principle of Laser Cutting Machine

    It is possible to make precise cuts by transferring dxf, dwg, igs, stl extension drawing files directly to CNC machines in various programs such as cad. Transferring the program drawings directly to the CNC machine makes it possible to make three-dimensional drawing and cutting. Before starting the cutting process, a number of pre-processes that need to be done on the CNC machine, such as sharpening the machine blades.

    A laser cutting machine is a machine that can be used on many materials. Many raw materials such as steel, plastic, wood, glass, paper, food, fabric and polyester can be used. Manpower is used very little, the device automatically cuts. Operations such as cutting, scraping and burning are done quickly, flawlessly and safely.

    The laser becomes a beam with the electricity supplied to the laser source. This beam is transmitted to the area to be treated with the lens and mirror, and the material is cut or scraped as desired. Laser machine comes in different sizes and types. Mini laser machine, household laser machine, medium-sized laser machine and large-sized laser machine are some device types.

    When the desired energy accumulation occurs in the laser beam, the movement of the beams begins. The rays directed at the optical glasses then move towards the lenses. The rays with intense energy, which start to reflect from the lenses, reach the material. According to the codes loaded on the CNC machine, the rays contact the metal and the cutting or shaping process begins.

What are Laser Cutting Methods?

The most prominent cutting method in the laser field is cnc cutting. Working in integration with programs such as CAD and CAM allows the application of various processes from metal to cardboard, plastic to wood material with zero error. Apart from this, there are also different cutting methods.

CO2 LASER CUTTING

Carbon dioxide is a preferred laser cutting method for processing materials other than metal. In the cutting process, the CO2 gas is activated with electricity and the cutting process is done. Processing of raw metals with CO2 is not suitable. This technique can cut products such as paper, cardboard and wood.

FIBER LASER CUTTING

In the method, also known as fiber laser cutting and optical cutting, all kinds of non-metal materials can be cut successfully. In addition to cutting, it is among the most suitable laser cutting methods in processes such as engraving and marking. It is at the forefront of processing gold, brass, aluminum, copper and similar materials.

CRYSTAL LASER CUTTING

   The cutting model stands out as a different type and variation of fiber optic laser cutting. It is a cutting method suitable for processing metal or nonmetallic materials. However, due to its high cost, crystal laser cutting does not come to the forefront as a preferred laser cutting method.

METAL LASER CUTTING

Applications made with CNC machines are called metal laser cutting and are among the most preferred methods. The functionality of cnc laser cutting machines and the fact that they allow different processes such as engraving during the cutting process play a big role in this. In addition, the possibility of all kinds of molds is effective in wide application area.

CNC Laser Cutting

Discussing more than one advantage of CNC laser cutting machines is possible. Among its prominent advantages is that it serves multiple functions such as scraping, cutting and shaping on the product to be applied. In addition, there are no mold costs and it works in integration with the drawing programs and allows cutting to any desired mold.

Making the cutting process faster and easier has positive effects on mass production. It both reduces the production process costs and effectively minimizes the time spent in production. In addition, operations such as scraping or cutting with these machines are performed with almost zero error. This provides an important advantage to keep the waste rate in manufacturing the products to a minimum.

Since we are talking about a device that works with a coding system, it does not require manpower for cutting steel and equivalent materials without the need for manpower. It is also possible to talk about a more reliable process since there are no security vulnerabilities during cutting. In summary, a cutting and sizing takes place untouched by human hands. This, in turn, affects a performance above the desired in terms of increased cutting quality and work efficiency.

There is no need for additional cutting material when working with a stainless laser cutting machine. This includes molding. This greatly contributes to work efficiency. In addition, another factor that makes it stand out is that details reflecting the corporate identity, such as the logo, can be easily engraved on hard surfaces such as metal.

Laser Cutting Advantages 

  1. Primarily, it provides cutting of all types of organic or inorganic products. Regardless of the surface hardness, laser cutting is at the forefront in many sectors in cutting and forming.
  2. It can also be expressed as a separation process that does not require a second process. In addition, edge sealing can also be applied in this cutting process to prevent unraveling for products such as synthetic materials or textiles. Or, depending on the type of material being processed, the procedures followed after the cutting process, such as mechanical closing – sandblasting, are not needed after the process.
  3. In these machines, integrated camera systems create landmarks. This is effective in automatically describing the original cutting path in case of undesired situations such as rotation, protrusion or deviation in the original template weld.
  4. There is no wear and perhaps this can be shown among its most important features. In addition, it does not cause problems such as blinding in the vehicle head parts. The reductions in maintenance costs of the anti-wear device are instrumental in achieving significant savings.

Usage Areas of Laser Cutting

Laser cutting is one of the most important application areas of various industrial processes. It is the laser cutting method used in the forefront of industry branches, especially from the automotive to the steel construction sector. Apart from these, it is also used in the fields of architecture and building construction.

Some of the CNC laser uses are as follows:

  • It may be desirable to make some shapes on any material. In this case, it is possible to apply the required shape on the surface to be applied in a short time without error with CNC laser cutting.
  • CNC laser cutting can also be preferred for marking on metal surfaces. Desired messages such as company logo, name and even contact information can be engraved on metal surfaces.
  • CNC machines that stand out in the industrial field, and the material patterns desired to be used in this sector are produced by laser cutting.
