Buying Guide for Laser Cutting Machine in 2023

Certainly! Here are some key factors to consider when selecting a laser cutting machine for steel:

1. Power:

The power of the laser cutting machine determines the thickness and quality of the steel that can be cut. Generally, a higher power machine can cut thicker steel with better quality. Determine the maximum thickness of steel you plan to cut and select a laser cutter with appropriate power.

The power of a laser cutting machine is one of the most important factors that determines its cutting capacity. Laser cutting machines are typically available in a range of power outputs, from around 150 watts to several kilowatts.

In general, the power of a laser cutting machine determines the maximum thickness of the material that it can cut. A higher power machine can cut through thicker materials than a lower power machine, up to a certain point. The maximum thickness that a machine can cut depends on factors such as the type of material being cut, the quality of the cut required, and the speed of the cut.

For example, a laser cutting machine with 150 watts of power can typically cut through steel up to around 1.5 mm thick, while a machine with 1 kW of power can cut through steel up to around 12 mm thick. Machines with even higher power outputs can cut through thicker materials, with some machines able to cut through steel plates that are several centimeters thick.

It’s worth noting that the cutting capacity of a laser cutting machine is not only determined by its power, but also by other factors such as the quality of the optics, the quality of the machine’s motion control system, and the type of laser source used. Therefore, when selecting a laser cutting machine, it’s important to consider all of these factors together to ensure that the machine can meet your specific cutting requirements.

2. Cutting speed:

Cutting speed is another important factor to consider when selecting a laser cutting machine. Faster cutting speed means higher productivity and lower production costs.

Cutting speed is an important parameter in laser cutting, as it affects the quality, efficiency, and cost-effectiveness of the cutting process. Here are some details on how cutting speed can affect a laser cutting machine:

Quality of the cut:

The cutting speed can affect the quality of the cut. If the speed is too high, the laser may not have enough time to fully melt and vaporize the material, resulting in rough, uneven edges or a poor cut quality. Conversely, if the speed is too slow, the laser can cause excessive heat buildup, leading to dross or slag buildup on the cut edges.

Efficiency of the process:

Cutting speed also affects the efficiency of the cutting process. Higher cutting speeds generally mean higher productivity and lower production costs, as more parts can be produced in a given amount of time. However, faster cutting speeds may require higher laser power or additional cutting passes to achieve the desired quality, which can increase the overall cost of the process.

Material properties:

The properties of the material being cut can also affect the cutting speed. For example, materials with high thermal conductivity, such as copper or aluminum, require lower cutting speeds to ensure that the heat is properly absorbed by the material.

Laser power:

The cutting speed also affects the laser power required to cut the material. Higher cutting speeds may require higher laser power to achieve the desired quality of cut.

Optimal cutting speed:

The optimal cutting speed depends on the material being cut, the thickness of the material, the type of laser used, and other factors. A laser cutting machine may have preset speed settings, or the operator may need to adjust the cutting speed based on the specific job requirements.

In summary, cutting speed is an important factor to consider when using a laser cutting machine. By adjusting the cutting speed appropriately, the operator can achieve the desired quality of cut, maximize the efficiency of the process, and minimize the cost of production.

3. Cutting quality:

The quality of the cut is crucial for many applications. The laser cutting machine should produce clean, precise, and burr-free cuts, which are essential for steel parts that require tight tolerances.

The quality of laser cutting is a critical factor in determining the suitability of a laser cutting machine for a particular application. Here are some key factors to consider when judging the cutting quality of a laser cutting machine:

Cut edge quality:

The quality of the cut edge is a key indicator of the overall cutting quality. A clean, smooth, and precise edge indicates that the laser cutting machine is operating effectively. Conversely, rough or uneven edges may indicate issues with the laser beam or cutting parameters.

Kerf width:

The kerf width, or the width of the cut, is another important factor to consider when judging the cutting quality. A consistent and accurate kerf width indicates that the laser cutting machine is operating properly and producing precise cuts.

Cutting speed:

The cutting speed can also affect the quality of the cut. A laser cutting machine that is cutting at the optimal speed for the material being cut will produce clean and precise cuts.

Material damage:

Material damage, such as excessive heat buildup or warping, can also be an indicator of poor cutting quality. A laser cutting machine that is operating effectively will produce minimal material damage.

Burn marks or discoloration:

Burn marks or discoloration on the cut edges can indicate that the laser cutting machine is not operating effectively, or that the cutting parameters need to be adjusted.

Tolerance:

The ability of a laser cutting machine to hold tight tolerances is an important factor in determining its cutting quality. A machine that can produce precise cuts with tight tolerances is essential for many applications, especially in industries such as aerospace or medical device manufacturing.

In summary, judging the cutting quality of a laser cutting machine requires evaluating several factors, including cut edge quality, kerf width, cutting speed, material damage, burn marks, and tolerance. By considering these factors, you can ensure that the laser cutting machine is producing the desired quality of cut for your application.

The maintenance requirements for the optics may vary depending on the type of laser cutting machine and the manufacturer’s recommendations.

Cooling system:

The cooling system is responsible for dissipating heat generated by the laser and maintaining the optimal operating temperature of the machine. The maintenance requirements for the cooling system may vary depending on the type of laser cutting machine and the manufacturer’s recommendations.

Motion control system:

The motion control system of the laser cutting machine controls the movement of the cutting head and the position of the material being cut. The maintenance requirements for the motion control system may vary depending on the type of machine and the manufacturer’s recommendations.

Electrical system:

The electrical system of the laser cutting machine includes the power supply, wiring, and electrical components. The maintenance requirements for the electrical system may vary depending on the type of machine and the manufacturer’s recommendations.

Consumables:

The consumables used in the laser cutting process, such as cutting nozzles and lenses, require regular replacement to maintain the quality of the cut and prevent damage to the machine.

In summary, judging the maintenance requirements of a laser cutting machine requires evaluating several factors, including the laser source, optics, cooling system, motion control system, electrical system, and consumables.
