In this presentation, we will explore the basics of tube laser cutting and plate laser cutting, compare the two methods, and discuss the factors to consider when deciding which method is best for your project. By the end, we hope you will have a better understanding of the differences and similarities between tube laser cutting and plate laser cutting, and how to choose the right method for your needs.

The Basics of Tube Laser Cutting

Tube laser cutting is a process that uses a laser beam to cut through tubes or cylindrical shapes. The laser beam is generated by a laser source, which can be either a CO2 laser or a fiber laser, depending on the specific material being cut. The laser beam is then directed through a series of optics and mirrors, which focus and guide the beam onto the surface of the tube. To accurately guide the laser beam and maintain the desired cutting path, the tube is often mounted on a CNC (computer numerical control) table, which uses precise motors to move the tube in relation to the laser beam. The laser beam heats up the material and vaporizes it, creating a precise, clean cut. Tube laser cutting has a number of advantages over traditional cutting methods. It is highly precise, with a tolerance of +/- 0.005 inches or less. It is also fast, with the ability to cut through materials at a high rate. In addition, tube laser cutting can be used on a wide range of materials, including metals, plastics, and composites. It is also particularly effective at cutting complex shapes and patterns.

The Basics of Plate Laser Cutting

Plate laser cutting is a process that uses a laser beam to cut through flat sheets or plates of material. Like tube laser cutting, the laser beam is generated by a laser source and directed through optics and mirrors to the surface of the material.

In plate laser cutting, the material is typically mounted on a CNC table, which moves the material in relation to the laser beam. The laser beam heats up the material and vaporizes it, creating a precise, clean cut.

Plate laser cutting offers a number of advantages over traditional cutting methods. It is highly precise, with a tolerance of +/- 0.005 inches or less. It is also fast, with the ability to cut through large sheets of material quickly. Plate laser cutting can be used on a wide range of materials, including metals, plastics, and composites. It is particularly effective for cutting large, flat sheets and is often used in industries such as automotive and aerospace.

Comparison of Tube Laser Cutting and Plate Laser Cutting

So, how do tube laser cutting and plate laser cutting compare? Both methods offer a number of advantages over traditional cutting methods, including precision, speed, and material versatility. However, there are also some key differences between the two methods that may make one more suitable for a specific project.

Tube Laser Cutting Process

In tube laser cutting, the metal tube is placed on a rotating chuck to allow the laser to cut at various angles. The laser beam is then directed onto the tube’s surface, following the programmed pattern, and the intense heat from the laser beam melts or vaporizes the metal along the cutting line. The rotation of the chuck enables the laser to cut complex shapes and angles smoothly.

Plate Laser Cutting Process

Plate laser cutting involves positioning the metal plate on a flat cutting bed. The laser beam is directed onto the plate, following the predefined path, and the focused energy cuts through the material. The cutting bed may have automated material handling systems that allow for continuous cutting without the need for manual intervention.
