Identifying Different Laser Cutting Processes
Oxygen Cutting
Oxygen cutting is one of the most common laser cutting processes used to cut zinc and other materials. In this process, a beam of laser energy is focused onto the material, and oxygen is used to blow away the incandescent particles that are heated and removed when the laser is applied. This allows for a clean and precise cut that is uniform and consistent.
Nitrogen Cutting
processes Nitrogen cutting is one of the common laser cutting processes for zinc. This process involves using a laser beam to cut through the zinc as if it were cutting through air. The laser beam is directed at the material and the heat from the laser is generated to create a kerf, or a small incision, in the material.
Once the laser has created the incision in the material, nitrogen gas is then used to blow away the molten material, eliminating the need for a separate cutting tool to do the work.
Flame Cutting
Flame cutting is a cost-effective and common laser cutting process for zinc. This process is most often used for thick metal sheets and creates a high quality, smooth cut. This cutting method uses a laser to heat the metal until it reaches its melting point.
When the metal has reached its melting point, a heated gas, such as oxygen, is used to blow away the molten metal, leaving a clean cut edge. The amount of heat generated is controlled by the power of the laser, gas purity and the arrangement of nozzle used for cutting.
Comparing Different Laser Cutting Processes
Oxygen Cutting
Oxygen Cutting, one of the common laser cutting processes employed to work with zinc, is a process in which an oxygen jet is used to cut or engrave the material.
