Laser cutting cost calculation

Are you wondering that how the laser cutting workshop charges you when you let them cut you steel plates? We’re doing laser cutting every day, would like to give a brief introduction of the cost calculation for laser cutting.

Before doing that we need to know how the laser cutter works. The simple statement is that the metal plate is melted, gasified and burned by the energy of the laser. Below is main factors which determine the cost of laser cutting. laser cutting cost calculation

Metal types: It is easy to understand that it takes different amount of power or energy to burn the different material as the composition is not same. It is more expensive to laser cut the stainless steel than carbon steel and the aluminum sheet is the most expensive one, under the same conditions. The aluminum is special, its surface would reflective the laser and it would cost more to laser cut it.

Thickness: This should be the first factor that comes to our minds. And we can calculate the laser cutting cost by the relationship of thickness, for example that the unit cost to laser cut 2 mm plate is two times of the 1 mm plate.

Start point: The laser head moves on the metal plate and it will move to another place and set a new start point when it finishes a closed plane. The start point will take extra energy and the laser cutting shop will charge it individually. So it depends on the design of the plate, the start point will be high if there are many closed planes, like there are many holes need to be laser cut.




Above listed is the main factors that will be considered by the laser cutting workshop. Don’t forget that all the bargain skills can be used; the cost will be cheaper if there’s a large quantity, you need to negotiate if there are a lot of small holes on the metal plate as the start point cost will be high.


Laser cutting and water jetting

There are a lot of articles about the laser cutting and the water jetting. You can get a lot information of the definition and the comparisons of these two cutting technology. Would like to compare them from the practical using.

Before doing that, would like to clarify that the laser cutting we mentioned here is for metals. Laser cutting for two main kinds of material: metals and non-metals. We call the laser cutting for non-metals is laser cutter engraver, it suitable for many materials like clothes, leathers, acrylic, bamboo, wood, etc, but it cannot cut metals which another one is for metals only.

Applicative Materials

Theoretically both of them can be used to cut ALL the metals, carbon steel, stainless steel, aluminum, copper, etc.

But we prefer to cut the aluminum by Water jetting. The explanation is that the aluminum material has the high reflectivity and diathermancy, so it is hard to cut or sometimes we cannot cut it by the laser cutting and it is harmful to the machine. The owner will not be happy if you use the machine to cut the aluminum.

Cutting effect

Laser cutting is better than water jetting without doubt. Laser cutting is faster and it has high precision. For the material thickness less than 3 mm, it is ok to use the water jetting, but if the material is very thick, it is hard and expensive to ensure the cutting effect by water jetting. The normal defect is that there’s a slope between the two surfaces of the cutting part, which is cause by the water.

Each of them has the advantage, depend on the requirements of the parts and the project. And the difference is not obvious when the material is not thick. Water jetting cannot compare with laser cutting on the speed and the precision but unique technology work out the difficulty of the cutting on the aluminum sheet.
