Factors to Consider When Buying a Laser Metal Cutter

When purchasing a laser metal cutter, you’ll want to consider a few factors before deciding. These factors include average lifespan, power, and types. These factors will help you decide which laser metal cutter suits your needs. Buying the right one can be a worthwhile investment.

Buying a laser metal cutter

One of the most important things to consider when buying a laser metal cutter is its cost. If you are starting, purchasing a used machine might be an excellent way to cut costs. However, you must be careful about the condition of the machine. Used machines may be faulty and are not guaranteed to last. If you are buying a used machine, be sure to check out the warranty and maintenance records. You should also check the operating hours of the machine. A sparsely used laser will last longer than one used extensively.

If you are looking for a metal cutter with the highest speed, you may want to consider a fiber optic machine. These machines have a high travel speed and are used for cutting thin metals like stainless steel. Large manufacturing companies typically purchase them. The maximum weight of a fiber optic metal cutting machine is 1.5 tons.

The average lifespan of a laser metal cutter

Laser metal cutters can process a wide variety of materials. Some metals, such as copper, are challenging to process, while others, such as aluminum, are complicated to cut. Aluminum alloys require a fiber laser because of their high reflectivity. Another standard metal cut using a laser is nickel, a high-temperature alloy with high reflectivity. It can also be cut with a flux or laser oxidation process.

The life expectancy of a laser metal cutter depends on several factors, including how well it is maintained. The laser tube can last up to seven years before needing to be replaced. The motherboard and power supply are also subject to failure. These components may need to be replaced or recharged, and the cost may depend on the complexity of the repair. Sometimes, hiring a technician to make the repairs may be necessary.

Power of a laser metal cutter

When it comes to cutting metal, a laser metal cutter is an excellent tool for the job. These cutting machines can slash metal as thin as three mm or as thick as 10 mm. They also come with unique cooling systems to keep the laser head cool. Other features include a ventilation system that gets rid of combustion products. They can also be used for milling mechanical components.

The power of a laser metal cutter is necessary for cutting thin sheet metals, so be sure to choose a high-powered machine for this job. This is because a higher-powered laser can cut thin sheet metal faster than a lower-powered one. However, the laser’s power reduces as the workpiece’s thickness increases. This slows the cutting process and increases the dwell time of the laser, increasing the amount of energy absorbed by the metal. In addition, the longer dwell time means that the metal can vaporize, resulting in more heat generated by the laser.

Types of laser metal cutters

Laser metal cutters can cut through a variety of materials. Different types use different lasers. Some are more suitable for cutting materials that require a high energy level, while others are better for less common situations. Regardless of which type you use, the process is generally similar. CO2 lasers emit an invisible beam of energy that passes through a series of lenses before cutting the material.

Laser metal cutters work by directing a laser beam through a lens or specialized mirror to a narrow spot of high intensity. This spot is called the focal spot. The focus of the laser beam depends on the material, its thickness, the beam’s shape, and the focal lens’s condition.


There are several factors to consider when buying a laser metal cutter. The lead time is an essential factor to consider. You will have to pay more for your project if you need the piece made right away. However, you cannot compromise on the quality. Another critical factor is the material being cut. Stainless steel, copper, cold/hot-rolled carbon steel, aluminum brass, and other metals are commonly cut using lasers.

Entry-level laser metal cutters are relatively cheap compared to other types of laser metal cutters. While cheaper versions of the machines can cut plastic, metal, and anodized aluminum, they can’t cut deep into the metal. However, these machines can be upgraded to include rotary axes.
