The Use of Laser Cutting in Sheet Metal Prototyping

Although there are several ways in which sheet metal can be shaped and cut, few are as accurate, reliable and inexpensive as laser cutting. The technology involved in laser cutting machine is so useful that a continuation, as well as improvement of their future capabilities, is inevitable.

Categories of Laser Cutting Tools

Laser cut is a flexible tool whose use can be applied in a wide spectrum of materials like stone, glass, plastic, wood, and sheet metal.

  1. CO2 laser

A CO2 laser cutter is a popular type of tool that is valued because it is easy to control and highly precise. A beam made of concentrated CO2 gas is activated by electricity to power the cut.

  1. Fiber Laser

A fiber laser uses glass fibers to enhance the potential of a seed laser. The result is a laser that is more powerful as well as more accurate than the CO2 laser cutter. A fiber laser is usually used for metals due to its focused and intense beam.

  1. Crystal Laser

A crystal laser is similar to a fiber laser, except that it uses pump diodes and crystals to generate the power of its beam. A crystal laser has a performance and application potential comparable to a fiber laser.

Benefits of Using Laser Cutting with Sheet Metal

There are numerous reasons why the use of laser cutting machine is the preferred method when developing a prototype sheet metal.

  • More Intricate

As a laser has an average size of just a few micrometers, it allows the accuracy to create and cut sheet metal prototypes that would not be possible if other methods were used. On the other hand, this results in an almost unlimited range of possibilities.

  • Finished Edge

The use of a physical technique like a blade, to cut metal sheets produces imperfections, such as roughness and burrs, along with the edge. For a lot of designs, these would need to be buffed out or otherwise eliminated which may increase the time it takes for the end user to get their product. The use of a laser eliminates this problem.

  • Scalability

The tools allow companies to cut as many or as few sheet metal prototypes as their customers want. In general, these lasers do not have to be adjusted or reconditioned to fit the design of a certain part. When adjustments are unavoidable, they are easier to perform when you use a laser cutter.

Laser Cutting and the Future

As of right now, CO2 laser cutters are still the industry standard, although fiber lasers are being rapidly adopted. Even though it is quite new, it is projected that fiber laser technology will become standard in the next 10 to 12 years. Several companies will continue to use their CO2 laser cutter along with their fiber lasers, providing them with more design options they can provide their customers. In addition, it could be combined with 3D printing to create accurate and reliable products for customers.…

The different techniques of laser cutting

There are several different machine tools for cutting metal plates. The most important techniques are plasma, water jet or laser. Each technique has specific advantages, depending on the application. However, when it comes to cutting sculpted contours and precise shapes, laser cutting represents the best solution. It also provides a good alternative to milling. Below, we will find out more about the different types of techniques that you can use in a laser engraver machine.

  • First, let’s understand the main advantages of laser cutting:
  • minimum thermal effort
  • very precise shapes, even in thicker material
  • precise cut
  • excellent repeatability thanks to the fact that there is no wear on the cutting tool
  • easy reanalysis

The different techniques of laser cutting

Beveling

With regard to bevelling, CO2 laser engraver and fiber cutting are both more accurate than plasma jet cutting, and faster than milling. A good CO2 laser engraver, for example, allows you to bevel ends up to 40 mm – the perfect solution for cutting steel sheets, for example.

Complex shapes and very small grooves

A good CO2 laser engraver enables you to cut complex shapes and reduced grooves up to a fraction of a millimeter.

Make sure you know the differences before picking your machine

When you have to opt for a laser engraver, it is essential to receive adequate support through the advice and experience of the specialists. What is your opinion regarding the integration of laser equipment into your machine? Is it supplied with the appropriate machining software and meets all cutting requirements for a wide range of materials? And why not set it and calibrate it? If it is starting from scratch, we recommend that you contact a qualified technician.

High Speed Recording / Marking

A laser machine that marks, engraves and cuts. It does not require two machines or transfer parts between them, and this inherent versatility further reduces costs per part.

Non-Metallic Materials

The laser engraver is ideal for cutting wood, plastic and Perspex. Provides a superb finish of Perspex ends, cuts plywood and can be used to punch paper and cardboard. As a versatile and economical method, laser cutting represents an excellent solution for suppliers in the communications and advertising industries. Learn more.

Simple re-updating

It is easy to achieve greater productivity with older or specialized machines by adding loading solutions, simply replace the laser system. The availability of ready-to-use solutions means you do not need to create your own configuration from multiple products. Dealing with any laser engraver is usually quite simple, so all you need to figure out is the kind of machine you need.

The alternative to milling: oxide-free cutting

The co2 laser engraver cut cleanly without leaving oxides of residue on the work piece. For this reason, the use of a co2 laser engraver is an excellent alternative to milling in stainless steel parts that require an exceptional finish. Given the additional productivity resulting from its speed, it makes sense to seek advice on the pros and cons of laser cutting as an alternative to milling.…
