1, laser cutting machine advantages: (1) laser cutting speed: sheet metal cutting speed can reach 10m/min, much higher than plasma cutting machine.
(2) High cutting quality: small deformation, smooth cutting table. Laser cutting groove is small, laser cutting surface can be directly used for welding without grinding.
(3) High cutting accuracy: laser cutting machine accuracy up to 0.05mm, repeated positioning accuracy up to 0.02mm.
(4) A wide range of laser cutting materials: metal and non-metallic materials can be used. There are metal laser cutting machine for non-metal and CO2 laser cutting machine.
(5) Laser can also be used for engraving, welding, drilling and other operations, powerful.
The disadvantages of laser cutting machine: (1) laser cutting machine cost is high, the initial investment and maintenance cost is high. At present, thin plate laser cutting has a high cost performance, but in the plate cutting efficiency is low, unless the quality requirements are high, otherwise improper laser cutting is used.
The advantages of plasma cutting machine: (1) the advantages of plasma cutting machine is that the plasma arc energy is more concentrated, the temperature is higher, the cutting speed is faster, the deformation is small, but also can cut stainless steel, aluminum and other materials.
(2) Plasma cutting machine has advantages in cutting thick plates, because in the process of cutting thick plates, very high cutting speed can be achieved, much higher than laser and flame.
The disadvantages of plasma cutting machine: (1) plasma cutting opportunity to produce harmful gas and arc: the principle of plasma cutting determines the arc intensity, noise and dust in the process of cutting, will pollute the environment to a certain extent. Underwater plasma cutting is generally used for medium and thick plate, so the cutting thickness is limited to a certain extent.
(2) verticality difference of the cutting surface: one side of the cutting surface will have a large bevel, verticality difference.
(3) In the cutting process, more cutting slag is produced on the surface of the cutting process. Since the process quality is not affected, the slag after cutting must be ground, which also increases the labor cost.
(4) The heat affected zone of plasma cutting is large and the slit is wide. It is not suitable to cut sheet metal because it will be deformed by heat.
(5) Cutting tools and other consumables are consumed quickly. Now the cutting nozzle mainly relies on imports, the cost is relatively high.
