Principle Revealed— Laser Cutting

Imagine focusing sunlight with a magnifying glass to ignite a piece of paper. The principle of laser cutting is similar to this, but the energy is concentrated and countless times more powerful. Laser cutting is like using a "pen of light" with extremely high temperatures to "write" or "cut" on materials with micron-level precision.

· Generating laser: The laser (like the "heart" of a machine) excites particles in a specific gas (such as CO2) or crystal through electrical energy, producing a beam of light that is pure in color, consistent in direction, and highly concentrated in energy.

· Conduction and Focusing: This laser beam is guided by a lens and a mirror and is focused by a special focusing lens into a very fine light spot (usually with a diameter of less than 0.1 millimeters). This light spot is like a "superpower needle tip", concentrating a huge energy density here.

· Cutting materials: When this high-energy light spot shines on the surface of the material, the local temperature rises sharply to several thousand or even tens of thousands of degrees Celsius in an instant (millisecond level), causing the material to melt, vaporize or reach its ignition point rapidly. Meanwhile, the cutting head will spray auxiliary gases (such as air, oxygen, or nitrogen) to blow away the slag and cool the cutting seam, thus forming a clean and smooth cut. The machine moves the cutting head or worktable through the numerical control system. The light spot, like an invisible pen, precisely "draws" along the preset path and eventually separates the material.

Core parameter: The control password for the effect

Adjusting parameters is the "art" of laser cutting, as they jointly determine the cutting quality, speed and energy consumption.

· Power: The energy output of the laser. The unit is usually the watt.

· Impact: The higher the power, the stronger the cutting ability (capable of cutting thicker materials), and the speed can also be faster. However, if the power is too high, it may cause the material to overburn or deform; if it is too low, it cannot be cut through. It needs to be adjusted in coordination with the speed.

· Speed: The speed at which the cutting head moves.

· Impact: The slower the speed, the longer the laser acts on a unit area, the deeper the cutting, but the greater the thermal effect (the edge may be more charred and yellow). If the speed is too fast, it may not be cut through. Fine patterns require a slower speed to ensure accuracy.

· Frequency: The number of times a laser pulse is emitted per second (Hz). For continuous-wave lasers, this parameter has little influence. It is crucial for pulsed mode lasers.

· Impact: High frequencies (such as above 5000Hz) are suitable for continuous cutting, and the cut surface is smooth. Low frequencies (such as 20-100Hz) form point-like pulses, which are suitable for engraving, drilling or cutting fragile materials and can reduce heat accumulation.

Core Advantages of Laser Cutting

1. Precision revolution

· Micron-level control: The slit width can reach 0.1mm (hair thickness)

· No tool wear: The laser "knife" never becomes dull, and the quality of the first piece is consistent with that of a thousand pieces

· Complex without difficulty: From simple straight lines to fractal patterns, the cutting complexity increases almost at zero cost

2. A model of flexible manufacturing

· Zero mold cost: Direct drive production from CAD files, especially suitable for:

· Prototype verification (1 piece is sufficient)

· Small-batch customization (10-100 pieces)

· Personalized products (each one different)

· Quick switching: Changing the cutting graphics only requires changing the file, which takes less than 5 minutes

3. Material universality

· Crossing boundaries: The same device can cut:

· Metals: steel, aluminium, copper

· Non-metallic materials: acrylic, wood, fabric

· Composite materials: carbon fiber, laminate

· Thickness coverage: From 0.1mm thin foil to 50mm thick plate (determined by power

· Paper and cardboard

· Leather and fabric

· Rubber

2. Metal materials (mainly using fiber lasers)

3. Other special materials

· Stone, glass, ceramics

· Certain engineering plastics

Such as PET, ABS, PP, etc. : They can be cut, but the effect varies depending on the specific composition and needs to be tested. The edges may melt or curl.

Use materials with caution and avoid them (safety first!)"

1.Absolutely prohibited materials (which may produce toxic/corrosive gases)

· Polyvinyl chloride (PVC)

· Polycarbonate (PC/ bulletproof glass)

· Materials containing (expanded) polystyrene (such as EPS foam) : Highly flammable, with flames spreading rapidly and extremely dangerous.

· Glass fiber reinforced plastic: Toxic smoke is released during cutting, and the glass fibers can contaminate and wear optical lenses in the form of dust.

2. Materials that require extreme caution and adequate ventilation

· Artificial leather and certain synthetic fabrics (such as chloroprene rubber) : They may contain PVC or other halogenated materials. They can only be attempted after confirming safety and having a strong exhaust system in place.

· Coated metals (such as painted and galvanized steel sheets) : Harmful smoke will be produced when cutting the coating, so ventilation should be enhanced. Galvanized sheet cutting is toxic.
