Galvanized Sheet Cutting Tips
Galvanized sheet is a widely used product in various industries such as automotive industry, shipbuilding, household appliances, electronics and electrical panels. In order to use this type of sheet in different applications, it is necessary to cut the galvanized sheet. From the past to the present, galvanized sheet cutting has been done in different ways. Fortunately, today there are many modern methods and devices for cutting galvanized sheet. Among the various methods of cutting galvanized sheet, laser cutting of galvanized sheet is in great demand due to its high accuracy and speed.
Galvanized laser cutting makes it possible to create any type of shape with any dimensions and in any thickness of galvanized sheet. In addition, the demand for galvanized laser cutting is expanding day by day due to its reasonable price and high accuracy. In the process of galvanizing laser cutting, it is necessary to observe some points in order to make sheet cutting in the best possible way. One of the services of Pivan Steel Company is cutting all kinds of steel sheets with advanced laser devices.
What is Galvanized Laser Cut?
Laser cutting of metals is one of the modern cutting technologies that is done by irradiating the laser beam of the machine to the steel sheet. Of course, in addition to steel sheets, the laser cutting method is also used for non-metals, such as wood, fabric, plastic, and leather. The working method of the laser cutting process of the galvanized sheet is that the laser rays are focused in a laser device through mirrors and lenses. Then the laser power causes the heat to rise on the irradiated surface, and finally, with the evaporation or melting of that surface, accurate and high-quality cutting occurs. Since laser devices perform cutting operations through the plan and program given to them and without the need for an operator or moving the metal sheet, very precise cutting is done and in laser cutting it is possible to cut all kinds of complex designs. The galvanized sheet cutting machine that is normally used in the industry is the fiber laser cutting machine. This laser cutting machine is one of the best modern machines for cutting galvanized sheets with a thickness of about 4 to 6 mm. In the fiber laser device, through the optical fiber, the laser beam is focused on the desired surface as a point. Finally, directing the laser power will result in a clean cut, without distortions, edges and protrusions.
Galvanized sheet laser cutting with oxygen
Oxygen gas is normally the gas that is used in galvanizing laser cutting. To cut the galvanized sheet, the oxygen gas purity must be above 99.6%. The higher the oxygen purity, the better the cutting quality. The advantage of cutting galvanized sheet with oxygen is its lower price.
Galvanized sheet laser cutting with nitrogen
Nitrogen is another auxiliary gas that is used in the laser cutting process of galvanized sheet, and its purity must be more than 99.5% during cutting. Using nitrogen to cut galvanized sheet increases the cutting price. The advantage of this method is cleaning the cutting area and not changing the color of the sheet edges during the cutting process.
The benefits of cutting the galvanized sheet with laser
Laser cutting of metals has many advantages compared to traditional and mechanical methods, and that is why its use is preferred in many industries.
High accuracy in cutting of galvanized sheet
In the laser cutting method of galvanized sheet, since the cutting is done automatically and by giving the program and design to the laser cutting machine, the cutting accuracy is very high. With laser cutting, the parts are cut with an accuracy of 0.2 mm. Also, any design and shape can be cut through the laser machine.
High speed cutting of galvanized sheet
Galvanized sheet laser cutting machines usually have a favorable speed due to the thickness of the sheet. Also, since the cutting is done by an automatic machine, they have the ability to cut with high precision and the same and coordinated in several pieces. In this method, it is possible to make several repeated cuts at the same time without the need to change tools.
Affordability
The price of laser cutting may initially be higher than other traditional methods of cutting galvanized sheet, such as manual cutting. But due to the lack of a human operator, reducing the amount of waste and cheap and accessible consumables is much more affordable. In addition, in this method, it is possible to create complex designs with minimal errors.
