A new printing technology for your business – CNC laser cutting
Metal cutting is one of the most important processes in the metal fabrication process. Only after the metals have been cut can they be shaped into the proper shapes and sizes.
The laser cutting procedure is one of the most preferred ways to get it done.
CNC stands for Computer Numerical Control
It is an exciting technology in which code is generated by the computer and is used to control machine tools. Drawings or designs are transformed into numbers using computer-aided design software (CAD). The numbers control the movement of tools used to mill the material.
Due to their precision and speed, CNC machines are more precise than manual machines and can handle more complex shapes, especially 3D pieces. In addition to handling a wide range of materials, their high level of precision makes them ideal for repetitive tasks.
The CNC laser cutting method can be effective if good-grade laser parts are used.
However, it has some benefits and drawbacks. Let’s have a look at them quickly.
Some advantages of CNC laser cutting
Engineers choose a laser cutting service because of the numerous benefits it provides:
- Extremely high accuracy and quality
Laser cutting makes use of a small, strong laser that provides a precisely focused beam of light to the material being cut. The high accuracy and nature, that is, the high quality of the cut material, are two of the cutting technology’s principles. The accuracy has been improved because of advancements in CNC laser cutting technology and the upgrading of the laser shaper head. Aside from high accuracy, the benefit is linked to the cutting time, which is gradually reduced.
Laser cutters are nearly usually the best choice when exceptional accuracy and precision are required. One of the reasons why laser cutting is so popular in the aerospace business, where tolerances are so tight, is because of this.
- Works with a wide range of materials
A Laser will have no trouble cutting metal, diamonds, plastics, wood, glass, or a variety of other materials down to size or assisting in the creation of complicated, detailed, and custom laser cut shapes.
- Low Electricity Use
This is a significant benefit in a world where companies are striving to work smarter, not harder, by increasing output while cutting expenses. A cutting machine consumes about 10kW of power, whereas other cutting operations consume roughly 50kW. This lowers total operating expenses while also lowering the environmental effect of laser cutting devices.
Disadvantages of CNC laser cutting
Although CNC laser cutting is used to make parts in practically every industry, it does have drawbacks that should be considered before getting started.
- Pricey
Since plastic produces gas when heated, laser cutting of plastic components can be costly. As a result, the laser cutting service provider will need to invest in a well-ventilated chamber, which is rather costly. When compared to waterjet or plasma cutters, lasers can be twice as expensive.
- Evaporation
This is unquestionably one of the technical procedure’s major weaknesses. When cutting materials like plastic, evaporation is more likely to occur. The gases generated during the cutting of plastic might be hazardous and toxic. If the laser beam comes into contact with human employees, it is dangerous. If it happens by accident, it might result in severe burns.
- Restrictions on the Metal thickness
Thick metals are still above laser cutting’s capability. Not all metals are suitable for CNC laser cutting. Copper and aluminum, for example, cannot be cut using this technology. The available machinery and expertise define the maximum suitable thickness.
