Sheet metal cutting is a fundamental process in mechanical engineering where a larger piece of material is divided into smaller parts or components. There are numerous methods of metal cutting, each offering different advantages and disadvantages, making it suitable for different manufacturing projects. In this article, we will look at the most common methods of cutting sheet metal and discuss their characteristics, applications and specifics.

Sheet metal cutting methods

  1. Guillotine cutting
  2. Laser cutting
  3. Water cutting (WaterJet)
  4. Oxygen cutting
  5. Cutting with an angle grinder


The selection of an appropriate sheet metal cutting method depends on the specifics of the project, the material, and the requirements for accuracy and efficiency. Each of these methods has its unique advantages and limitations, which should be carefully evaluated before starting work. In the following parts of the article, we will take a detailed look at each of these technologies to help you make the best choice for your needs.

Guillotine cutting

A guillotine is a traditional sheet metal cutting method where a sharp knife cuts the sheet metal at right angles. This method is suitable for straight and precise cuts, but can be limited for more complex shapes and thick materials. Its advantages include speed and low cost, but limited flexibility and accuracy in complex cuts are its disadvantages.
Guillotines are among the most common sheet metal cutting tools. They are used for precise cutting of metal sheets in various sizes and shapes. Guillotines are efficient and enable high-speed production.

Water cutting (WaterJet)

A waterjet cutting machine uses water under very high pressure, sometimes mixed with an abrasive material (sand), to cut metal. This method is universal and can cut almost all materials without thermal deformation. Its main advantages include accuracy and lack of thermal deformation on the material, but maintenance costs and the need for specialized equipment are its disadvantages.
This technology is very precise and can cut various metals such as aluminum, copper and stainless steel. The WaterJet is ideal for an application where cut quality is critical and finances are not an issue.

Laser cutting

Laser cutting uses a concentrated beam of light to precisely and quickly cut metals. This method is ideal for complex and detailed shapes, offering high precision and clean edges. Disadvantages include high initial investment and maintenance costs, but advantages in accuracy and speed make it a popular choice for many applications.
This technology is suitable for complex shapes and offers high accuracy. Laser cutting is an efficient process with minimal impact on the material and low energy consumption, making it an economical and cost-effective choice.

Oxygen cutting

Oxygen is a cutting method with a gas torch that melts the metal and cuts it. It is suitable for cutting thick and strong metals. Although slower and less accurate than other methods, oxygen is effective and economical for heavier materials and thicker sheets. This method is often used in heavy industry. Although slower and less accurate, oxygen is efficient and economical for processing thick materials.

Cutting with an angle grinder

An angle grinder is a hand tool that uses an abrasive disc to cut metals. It is flexible and suitable for small projects and field conditions, but requires experience and attention to achieve accurate and clean cuts. For safe cutting, follow these steps:
– Wear safety glasses and earplugs;
– Use a permanent marker to mark the cut line;
– Always hold the angle grinder with both hands and follow the marker line to cut the metal.
