CNC and laser turning are both material cutting tools. Each process has its unique advantages for specific types of operation. So, you cannot say whether CNC or laser cutting methods are better in every aspect. Based on the type of cutting work and other factors, you have to determine which one is better for you. So, let us take a look at some of those factors:
The Difference In The Cutting Process:
Let us first focus on the operation procedure for both types to get a clear view. The CNC cutting method uses mechanical tools to perform the cutting operation. The mechanical cutting tool is run by computer numerical control to rotate at very high RPM during operation. When the tool is lowered, it makes physical contact with the material you are working on. It generates a high frictional force at the contact surface. So, small material particles are eroded to continue the cutting.
The laser cutting tool is run by computer numerical control, but you don’t need any mechanical tool. The very high-intensity laser ray is focused on the point of cutting, which melts and evaporates the particles to perform the cutting. That means the laser cutting method is thermal.
Cost Of Operation:
It is a well-known fact and undeniable information that laser methods are costly. This is primarily due to the high cost of laser cutting machines. Comparatively, with CNC cutting, you can perform cutting operations at very low costs. This is why CNC machining is extremely popular for different types of industries.
Quality Of Cutting Edges:
The laser cutting method is unique because it uses a high-intensity light beam. Due to the uniqueness in the cutting method, you can get sharp cutting edges. This results in cleaner and sealed edges.
But this will also leave a fine trail of burning spots at the edges, especially when cutting plywood. Comparatively, the CNC cutting method uses a mechanical cutting method that leaves a slightly dull edge, but it will not leave a burning mark.
The simplicity of cutting operation:
CNC cutting methods are excellent for performing simple straights, diagonal, cervical, and simple cuts. This is advantageous, especially if you are working on wood-based material.
Creative and complex design patterns:
To perform cut works on highly complex patterns, the laser cutting method should be the best option. Because with CNC cutting methods, you cannot perform neat operations on complex designs. There is always a risk of material wastage.
Thickness Of Material:
With laser cutting, you can only perform work on thin sheets of material. Comparatively, with CNC cutting, you can perform cutting operations on deeper materials. So, you can easily work following three-dimensional geometries.
Which One Is Better:
Now that all the relevant factors are discussed, we can vote for a better cutting method. We can simply say that if you want to perform cuts for simpler designs that don’t require extremely high-quality finishing on thicker materials and also with a low-cost investment, then CNC cutting should be the better choice for you.
Comparatively, if you are ready to sacrifice the extra cost to get a high-quality finishing on a complex-designed workpiece, the laser cutting method should be your better choice.
