What is plasma cutting

Plasma cutting is a processing technology that uses high-temperature plasma arc to melt and cut metal materials. Its core is to achieve efficient cutting by generating high-energy plasma through ionized gas.

1. Basic principles

Plasma generation

When gases such as compressed air, nitrogen or argon pass through the nozzle of the cutting torch, a high-voltage arc is applied between the electrode and the workpiece, causing the gas to ionize and form plasma (ionizing high-temperature conductive gas, with a temperature reaching 10,000-30,000℃).

Cutting process:

High-energy plasma arcs focus on impacting the local area of the workpiece, rapidly melting the metal. At the same time, high-speed gas flow blows away the molten material, forming a cut.

System Composition

Power supply: Provides DC high voltage (usually 200-400V) to maintain arc stability.

Cutting torch: Core component, including electrodes (commonly hafnium or tungsten), nozzles (made of copper, to confine the arc), and gas channels.

Gas supply

Working gases (such as air, O₂, N₂) are used to generate plasma;

Auxiliary gases (such as CO₂) protect the cutting surface.

Cooling system: Water cooling or air cooling to prevent the cutting torch from overheating.

Technical Features

Advantages:

1.It can cut all conductive metals (including stainless steel, aluminium, copper, etc.);

2.The speed is faster than that of oxyacetylene cutting (for example, 20mm carbon steel can reach 2m/min).

3.High precision (incision width approximately 1-3mm);

4.No preheating required, suitable for automation.

Limitations:

1.The equipment cost is relatively high.

2.When cutting thick plates (>50mm), the bevel Angle is relatively obvious.

3.Protection against noise and ultraviolet radiation is required.

Process type

Ordinary plasma cutting: Single gas, suitable for medium and thin plates.

Fine plasma cutting

The arc is compressed by technologies such as eddy current rings, achieving higher precision (cut width ≤1mm), and is suitable for precision processing.

Water recompression plasma cutting

The water flow wraps around the plasma arc, reducing smoke and dust and improving the quality of the incision.

Application fields

Industrial manufacturing: sheet metal processing, auto parts, pipe cutting.

Architecture: Steel structure, metal frame.

Maintenance: Quickly remove or repair metal parts.

Artistic creation: Cutting of complex metal shapes.

What are laser protective lenses?

Laser protection lenses, also known as laser window lenses or optical window lenses, are mainly used in YAG fiber laser cutting machines, marking machines, welding machines, engraving machines and other laser equipment. They are used to block or prevent high-temperature spatter, protect focusing lenses, electronic sensors, and semiconductor components, and prevent spatter from splashing onto the lens and causing damage to it. The precision requirements of processing need to be guaranteed by regularly replacing the protective lenses. At the same time, this lens cannot weaken the laser output energy. Mechanical properties such as light transmittance, surface shape accuracy, thickness, parallelism, and base material are important parameter indicators for laser protection lenses.

Follow these easy steps, when cleaning or changing your lens, to help maximize the life and performance of your lens

Avoid touching coated surfaces of the lens and hold the optic by its sides

Wear powder-free finger cots or latex gloves when handling

Do not use any tools or sharp objects when handling the lens or when removing it from its packaging

Ensure the work surface is clean and free of oils, grease and dirt

Do not place the lens on hard surfaces as they scratch easily

Once the optic has been unpacked, carefully place it on the lens tissue in which it was originally wrapped
