Guide For Buying a Laser Cutter in 2020

Laser cutting machines are sheet metal machines that engrave, cut, drill, and mark various materials with invisible lasers.

Laser cutting machines are used in various fields in the world. From relatively soft materials such as paper, cloth and leather, to acrylic and metal cutting, to medical uses. Emit has the best laser cutter for sale. This is a processing machine that can cut and mark materials in any shape using laser light.

There are three main types of laser cutting machines: fiber laser cutter, CO2 laser cutter, and YAG laser cutter. As another application, A laser cutting machine is also called laser engraving machine, and each feature is explained briefly below.

Fiber laser Cutting Machine

A fiber laser cutter machine that has recently emerged, and is equipped with an oscillator (a device that generates laser light) that generates laser light using a mechanism completely different from conventional CO2 laser cutter.

Features include running costs that are much lower than CO2 lasers, and the ability to process highly reflective materials such as copper and brass.

The reason why running costs can be reduced is because laser gas is not required, energy costs can be saved by increasing energy efficiency, and oscillators are maintenance-free.

However, it is also a machine with high initial cost. It is sold at about 1.5 times the price of a CO2 laser cutting machine, so if the operating time is short, you cannot take advantage of the low running cost. The effect is remarkable when running for a long time.

CO2 laser cutting machine

Although fiber laser cutter have appeared, CO2 laser cutting machines are still the center of the market for laser machines. Discharge is performed using laser gas as a medium, and the material is cut through mirrors and lenses. The cost of CO2 laser cutter is lower than fiber lasers, and high quality cut surfaces can be obtained, especially when processing thick plates. There are two-dimensional laser cutting machines that mainly process sheet materials, and 3D laser cutting machines that can perform everything from cutting to 3D molded products to welding. It is the most popular laser cutting machine as a standard for sheet metal machine.

YAG laser cutting machine

YAG laser cutter is suitable for welding and cutting various metals, and is also widely used in the medical industry.
Compared to TIG welding, YAG laser concentrates heat in a very narrow range and has a high welding speed. Furthermore, since post-processing is almost unnecessary, it contributes to shortening of the process.

Configuration of laser cutting machine

Laser cutting machines usually have some accessories other than the main body. Although there are slight differences depending on the model and manufacturer, in addition to the main unit, there are an oscillator, chiller, dust collector, cooling tower, compressor, etc. Since it depends on the installation space, please consult us about what kind of accessories you need to install.

Guide for buying a laser cutter

1. 2D or 3D?

Laser cutters are classified into 2D lasers for processing sheet materials and 3D lasers for processing 3D objects. 2D processing is of course possible with 3D lasers. In the first place, 3D lasers are more expensive, so if you plan to process only sheet materials, you should choose a 2D laser cutter.

2. Work size

Basically, there is a standard for the size of the machine, and in the case of 2D laser, the machine is prepared according to the 4 ‘x 8’ size or 5 ‘x 10’ size steel plate. So you should buy different laser cutting machine according to the area of cutting material.

3. Processing plate thickness

Depending on the material, the required power increases as the thickness increases. For example, if you want to cut 6mm of iron, you can use a laser machine with a 2KW output. In the case of “I want to cut 16mm!”, you can choose 4kw. In recent years, it has come out as much as 6kw and can be cut to about 24mm. However, when the thickness is more than 25mm, plasma cutting machines and gas cutting machines come into play. Stainless steel and aluminum can also be processed, but the conditions are different from iron, so please consult us separately.

4. Processing material

Basically, a laser cutter can process iron, stainless steel and aluminum. If you want to process copper or brass, you need to select a fiber laser because CO2 laser processing is difficult.
