Main Components

Inside a cnc laser cutting machine, there are many important parts. Each part helps with the cutting job:

• Laser Source: This part makes the laser beam. You pick the power level for your material and how fast you want to cut. The laser source decides how deep and quick you can cut.
• CNC Controller: This system sets the laser’s path and speed. The cnc controller lets you change laser cutting settings like power, speed, and focus. You control every cut with this system.
• Cutting Head: The cutting head holds the nozzle, focusing lens, and tracking system. The nozzle keeps the laser at the right distance from your workpiece. The focusing lens points the laser beam at the material. The tracking system changes the height for different thicknesses.
• Assist Gas System: This system blows away melted bits and keeps the cut clean. The air supply has filters and pipes to send gas like oxygen or nitrogen. The right gas helps you cut faster and get smooth edges.

Other main parts include servomotors for moving the machine, reducers for speed, an industrial chiller to cool the laser, a strong working bed, and a dust collector for smoke and dust.

Step-by-Step Cutting Process

You follow steps when you use a laser cutting machine. Each step helps you get good results.

Focusing the Laser

First, you focus the laser beam on the material. The lens and tracking system help the beam hit the right spot. You set laser cutting settings like focus and power. The laser makes a tiny, hot spot that melts or turns the material into gas.

Material Interaction

The laser works with the material very fast. You set the cutting speed and change settings for different metals or thicknesses. The laser melts, burns, or blows away the material. The assist gas system removes melted bits and keeps the cut smooth. You get clean edges with little heat damage.

Edge Formation

You watch the edge form as the laser moves along the path set by the cnc controller. The process makes smooth, exact edges. You can cut hard shapes and small details. The laser does not touch the material, so you do not get scratches or bends. You change laser cutting settings for each job.

Tip: You can change the cutting speed and other settings to get the best results for each material.

Here is a table that shows how laser cutting compares to old cutting methods for accuracy and repeatability:

Laser cutting gives you better repeatability and finer tolerances. The process does not wear out tools, so you keep high accuracy for many jobs.

Laser Cutting Technology and Techniques

Fusion Cutting

Fusion cutting is a common way to cut metals with lasers. The laser melts the metal along the line you want to cut. You use a safe gas like nitrogen to blow away the melted metal. This keeps the edge neat and smooth. Fusion cutting works well for stainless steel and aluminum. It is good for jobs that need high accuracy. You get edges that are clean and have almost no rough spots. Many industries use fusion cutting because it gives exact results. You do not need much extra work after cutting.

Tip: Fusion cutting gives you smooth edges, so you can put parts together right away.

Flame Cutting

Flame cutting uses a laser and oxygen to cut thick metals. The laser heats up the metal. Oxygen makes a chemical reaction that adds more heat. This helps you cut carbon steel and other thick metals easily. Flame cutting is used for big jobs like building and ship making. It is fast and works well for thick plates. The edge may not be as smooth as fusion cutting. You might see some rough spots or leftover bits. You may need to clean up the edge after cutting.

Note: Flame cutting is best for cutting thick steel fast, but it is not as exact as fusion cutting.

Sublimation Cutting

Sublimation cutting is a special way to cut non-metal materials. The laser turns the solid material straight into gas. It does not melt first. You use sublimation cutting for wood, plastic, and cloth. This method lets you make detailed shapes and patterns. The laser does not heat up the area much. You get smooth edges and do not burn or bend the material. Sublimation cutting is great for making signs and decorations that need fine details.

Tip: Sublimation cutting helps you make detailed shapes and patterns, so it is good for creative projects.

Comparison Table

You can look at this table to see how these cutting methods are different:

Laser cutting gives you many choices for different materials and jobs. You pick the method based on what you are cutting and how exact you need it. Fusion cutting is best for clean metal edges. Flame cutting works for thick steel. Sublimation cutting lets you make detailed designs in non-metals. If you know these ways, you can choose the best one for your project and get great results.

Precision vs. Speed

When you use a laser cutting machine, you often think about two important things: precision and speed. Precision means how exact your cuts are. Speed means how fast you finish your job. You want both, but sometimes you need to choose which one matters more for your project.

If you need very exact parts, you set your machine for high precision. You slow down the cutting speed and use a fine laser beam. This helps you get smooth edges and tight shapes. You use high precision for jobs like making medical tools, electronics, or airplane parts. These jobs need every piece to fit perfectly.

If you want to finish many parts quickly, you set your machine for high speed. You use more power and move the laser faster. This works well for simple shapes or big batches. You use high speed for jobs like making signs, cutting fabric, or building parts for cars. You finish more pieces in less time.

Tip: You can change your machine’s settings to get the right balance. If you want smoother edges, slow down the speed. If you want to finish faster, increase the power and speed.

Here is a table to help you see the difference:

You can use a fiber laser cutting machine, like the ones from KRRASS, to adjust both precision and speed. You pick the right power level and focus for your material. You use the CNC controller to set the path and speed. You get the best results when you match your settings to your job.

Sometimes you need to test different settings. You cut a sample piece and check the edge. If the edge looks rough, you slow down the speed. If you need to finish faster, you try a higher power setting. You learn what works best for each material.

Note: You do not have to choose only precision or speed. You can find a balance that fits your needs. Modern machines let you change settings easily, so you get the results you want.

You see that precision and speed work together. You decide what matters most for your project. You use your machine’s features to get the best outcome every time.
