There are different cutting techniques for raw materials to consider as a hobbyist fabricator. One of the most beneficial choices is laser cutting because the machine is highly precise in translating the pertinent designs. In addition, the thin stream of amplified light does not distort the cut edges. Therefore, you will not need to invest in finishing processes to restore aesthetics. Generally, you can get laser cutting services from specialist dealers in the fabrication industry.
On the other hand, you can purchase your own laser equipment and perform the cutting tasks in your residential workshop. This choice will provide flexibility and allow you to grow as a fabricator. If you choose this option, it is critical to ensure that the cutting system in the machinery matches your fabrication requirements. Here is a short description of the primary types of technologies incorporated into laser equipment for cutting processes.
Laser cutting equipment can utilise vaporisation techniques to cut the raw material for fabrication. Basically, the beam of amplified light is directed on a specific spot on the material. This will heat the area to melting point and the material will evaporate, leaving a hole. The point will serve as a starting keyhole to elongate the cut in the raw material through the same vaporisation method. You should acquire this cutting system if you plan to handle non-melting materials like wood, some plastics, and carbon.
Brittle materials are susceptible to cracking when exposed to high temperature. The breakage can be attributed to unexpected expansion of the substance. This is an advantageous attribute in manufacturing, and the pertinent technology is incorporated in the application of some laser cutting machines. Basically, in this type of equipment, the beam is exposed to a specific area until the material expands and cracks. The crack is extended systematically using the beam as the guide. This cutting system is perfect for glass fabrication projects.
Melt and Blow
If your fabrication activities are focused on materials that can melt, you should choose a laser machine with melt and blow cutting capabilities. Basically, this equipment has a high temperature laser which can melt diverse raw materials. When the substance is melted, high-pressure gas is released and the jet blows away the molten material from the cut section. This process is effective when handling fabrication metals because they melt relatively easily in the presence of heat. The pressurised gas flow accelerates the process and eliminates the need to heat the raw material continuously until the metal melts.
