How much do you know about metal Laser cutters?

Metal laser cutting machines are widely used in the industrial manufacturing industry, but most customers don’t know how to choose fiber laser cutting machines. Now this article will tell you how to buy cheap laser cutter equipment and what you should pay attention to.

What is a metal laser cutting machines?

Metal laser cutting machines is a laser cutter equipment specially used to cut and process metal materials. The mainstream on the market is co2 laser cutter, fiber laser cutter, and YAG laser cutter. Among them, co2 laser cutting machine has strong cutting ability and wide range. The mainstream laser cutting equipment in the market, fiber laser cutter is the latest technology, coupled with relatively low technical requirements, the metal fiber laser cutter equipment is gradually popular.

How does the fiber laser cutter work?

The matel cutting machine is a dense beam of light in the form of light with high concentration and high heat through the laser stroke. The beam irradiates the surface of the material, uses the high temperature generated to melt the material and uses the high pressure gas generated by the beam coaxial to remove the melted Exhaust gas material, so that the purpose of cutting metal is achieved.

From here we can see that laser machine is essentially different from traditional machining. The laser cutting machine generates a laser beam through the laser transmitter. This laser beam will enter the external circuit system and converge to form a high-density and high-intensity laser beam, and then directly irradiate the surface of the material.

After the material is irradiated, its temperature rises rapidly until it reaches its surface. At this time, the material begins to vaporize to form holes, and then the laser beam begins to move on the surface of the material to form a cut.

Most materials can be cut by laser. Therefore, laser cutting plays a very important role in industrial manufacturing. Most materials can be cut and deformed regardless of their hardness. However, it does not deny that some high emissivity materials will also make laser cutting very difficult or even impossible to cut because of their excellent thermal conductivity properties.

The metal laser cutting machine is also loved by many electrome chanical manufacturing industries because of its features such as no burrs, no wrinkles, and high processing accuracy. Because of its precise micro-control operation, CNC laser cutting can cut materials of different shapes and sizes very conveniently.

Questions to consider when buying an industrial laser cutters

Laser cutting machine is actually a very high threshold market, the purchase of equipment must be polished, very familiar with the purchase of equipment to buy quality and quantity of equipment, even if the long-term business of laser cutting machine bosses also have to go out of sight, not to mention just entering the line of white.

But just entered the industry, whether for the purpose of industry testing, or the hands of the money really can not be turned around, the demand for used equipment is real, so we are today to talk about the purchase of laser cutting machine as an example, what issues should be considered when buying laser cutting equipment.

First, set the right mindset

Buy laser cutting machine do not hold the mentality of picking up, picking up is a probability event, hold this mentality to buy equipment, either do not happen to be the right equipment to delay the schedule, or for the benefit of reluctantly bought a less suitable for their own equipment, or be used to take advantage of this mentality to cheat the funds.

So we buy laser cutting machine is the first priority is to set the right mindset, firmly believe in the truth that a penny is worth a penny, the face of equipment significantly lower than the market price must be vigilant.

Second, check the identity

Now the network has developed very convenient, before the field inspection equipment, we can understand some of the basic information about the equipment through a number of ways.

For example, the equipment purchase contract, manual, after-sales service, etc., if inadvertently lost, we can also ask the seller to take a picture of the nameplate on the body, mainly to understand the age of the equipment and the manufacturer’s sources. Years of use and manufacturers sources related to the quality of equipment, service life, and naturally, our prices are closely related.

Third, field visits

We can watch the pictures and videos of the equipment through the Internet, and after the initial satisfaction, we also need to visit the field to see the equipment with our own eyes.

First look at the appearance of the equipment, and then look at the details of the equipment, check the degree of wear and tear of the parts of the equipment, especially important accessories, such as laser cutting machine cutting head, laser, motor, etc., these important accessories if there is a problem, buy back often break down, the cost of repair and replacement will undoubtedly increase our costs.

Fourth, open the machine to check the goods

Everything looks almost right, it is also necessary to turn on the machine for a trial run.

Normal start-up, add materials, observe whether the equipment is running normally, there is no abnormal heat or abnormal noise, the efficiency and quality of production is in line with production requirements, etc.

V. Sign the contract

The contract should include the name of the equipment, model, quantity, main parameters, scope of supply, price and payment method, the responsibility of both sides, compensation method, etc. If unpleasant things happen subsequently, at least we can take up the legal weapon to protect ourselves.

4 Features of CO2 laser cutting machine

  • In the CO2 laser cutting machine, gas is the medium that generates the laser beam, and the beam is transmitted through the reflector. The maintenance cost is high, the front mirror and the rear mirror are expensive, the life of the turbine bearing is short, and the replacement cost is high.
  • The CO2 laser has a complex structure, high maintenance costs, and large beam divergence during processing, which is not suitable for large-format processing. The speed is very slow when processing thick metal plates. The cutting speed of fiber laser cutting machine is 2-3 times higher than that of CO2, and the cutting section is smooth.
  • Due to the purity of CO2 gas, the CO2 laser cutting machine will be polluted in the resonant cavity and needs to be cleaned regularly, which requires more routine maintenance. For a multi-kilowatt CO2 laser cutting machine, this item requires at least US$20,000 per year.
  • The CO2 laser cutting machine can cut non-metallic materials, such as cloth, leather, wood, acrylic, paper and other non-metallic softer materials.

Comparison of laser cutting machine and laser engraving machine

The laser cutting machine can cut all kinds of complicated graphics. Because it uses light energy to cut, it does not need a fixture. Just put the material on the worktable and cut it, so there will be no damage to the surface of the material, which is different from others. For cutting, such as a sawing machine, it can only cut straight lines, not irregular shapes, arcs, etc.;

The laser engraving machine cannot process some small graphics, and in the process of processing, it needs a fixture, which also damages the surface of the material, and when cutting, it will have an R angle, which is more troublesome to operate.
