Many important criteria should be considered when choosing a laser cutting machine for metal. For instance, the fibre laser cutting machine may be a suitable choice for businesses seeking high-speed and high-precision cutting. When choosing the machine, the following factors should be considered.
Power of the laser
The laser's power determines the thickness of the material to be cut. Businesses should select the machine that has adequate power to meet their metal cutting requirements. Machines with high-power lasers are suitable for thick metals. On the other hand, machines with low-power lasers are suitable for thin metals.
Working area
The working area of the cutting machine determines the size of the project. Hence, businesses should select a machine with a sufficient working area for their metal cutting projects. Large enterprises that deal with larger metal sheets should pick fibre laser cutting machines. They should also consider the compatibility of the machine with the material they work with.
Stability and reliability
For businesses that carry out large production volumes, the stability and reliability of a machine are paramount. Therefore, it is vital for business owners to consider the quality of the components used in the machine's manufacturing. They should also consider the reputation of the manufacturer. Additionally, they should look for reviews from other customers in similar businesses.
Operational costs
Enterprises should consider the operational costs of using the fibre laser cutting machine, including power consumption and maintenance. Generally, laser cutting machines are more efficient when cutting metals. Therefore, they consume less power.
Control system
The control system of the fibre laser cutting machine should be user-friendly. That will ensure the workers can easily operate it. Consequently, businesses should look for machines with advanced control technologies. The technologies will ensure the workers can execute complicated cutting designs with accuracy.
Speed
Fibre laser cutting machines are known for their high speed in cutting metals. Businesses that require large production rates should consider the cutting speed of the machine. It will enable them to complete their projects quickly. Moreover, the speed will also reduce the operational costs.
Additional features
Many modern fibre laser cutting machines come with extra features. For instance, they have automatic adjusting focusing systems and detecting thickness systems. Businesses should consider such additional features. They are suitable for automating the cutting process and increasing its accuracy.
Fibra laser cutting machines are brought to the market with various specifications based on their intended use. For instance, the working area and laser power options may vary depending on the application. They all, however, require maintenance to improve their durability and operational efficiency.
The main parts of the fibre laser cutting machines include the laser source, cutting head, motion system, worktable, control system, and the cooling system.
Laser source
Laser sources used in fibre laser cutting machines include diode pumps, and fibre lasers like Raycus and IPG. The amount of laser power is dependent on the laser source. A variety of sources are available to work with various materials and thicknesses. Most machines have sources with power ranging from 500W to 10kW.
