With the gradual maturity of domestic lasers, to break the monopoly of the price of imported lasers, now the manufacturers of domestic 4kw fiber laser cutting machine also with the price reduction, but also gradually increased, which also means that the domestic demand for laser cutting machine is also growing.
The characteristics of flexible metal processing fiber laser cutting machine, has been recognized by many sheet metal customers, its cutting speed compared with the traditional processing equipment, is a great advantage. Speed is the fundamental decision of efficiency, so in the use of the process, how do we improve the cutting speed, increase the use of efficiency? The following high-energy laser will give you an analysis.
First of all, we have to understand several factors that affect the cutting speed:
1. Different materials
Laser cutting machine cutting metal materials are mainly divided into, aluminum plate, stainless steel, carbon steel, copper plate and alloy materials. Different material characteristics are different, the laser absorption rate is not the same, so in the case of the same thickness of the material, the cutting speed is different.
2. Thickness is different
The thickness of the material is different, the required perforation time is different, in the cutting process, the thicker the thickness, the greater the laser energy required, the slower the cutting speed.
3. Different output power
Power is the most important factor to determine the cutting speed, the greater the power, the greater the laser energy, the faster the cutting speed of the sheet, the following several different power for example, you can compare the cutting speed of different materials with different power;
A, the maximum cutting speed of different materials of 500W fiber laser cutting machine: carbon steel maximum speed 13m/min; Stainless steel maximum speed of 14m/min; The maximum speed of aluminum plate is 5.5m/min; Maximum speed of copper plate 5.5m/min;
B, 1000W fiber laser cutting machine different materials cutting maximum speed: carbon steel maximum speed 24m/min; Stainless steel maximum speed 24m/min; The maximum speed of aluminum plate is 10m/min; The maximum speed of copper plate is 10m/min;
C, 2000W fiber laser cutting machine different materials cutting maximum speed: carbon steel maximum speed 28m/min; Stainless steel maximum speed 28m/min; The maximum speed of aluminum plate is 25m/min; The maximum speed of copper plate is 16m/min;
D, 3000W fiber laser cutting machine different materials cutting speed: carbon steel maximum speed 35m/min; Stainless steel maximum speed 35m/min; The maximum speed of aluminum plate is 43m/min; The maximum speed of copper plate is 35m/min;
Enhance the cutting speed of laser cutting machine
Debugging parameters of laser machine to improve cutting speed.
Machine parameter setting is one of the main reasons that affect the cutting speed of the machine. In general, if the parameters are not adjusted well, its cutting speed is not good. Parameters, just like people in the driving, starting, accelerating and a series of actions related to the action, if the parameters are not set well, just like the car in the starting, you hang a second gear to start, in the start, it will have jitter. When adjusting this parameter, we should pay attention to the following points:
1. Initial speed: As the name implies, this setting is the starting speed of the machine, which is like the starting speed of the car in the process of driving. Many customers have the misconception that the higher the initial speed, the better, but this is actually a mistake. If the initial speed of the laser machine is set too high, then the machine jitter will be very large.
2. Acceleration: Acceleration means the speed of the refueling door in the process of driving the car, which is the time taken from the initial speed to the normal cutting of the machine. When the machine is cutting different patterns, it is a process of constantly starting and stopping. If the acceleration is set too low, the machine will cut slowly.

At present, fiber laser cutting machine has gradually replaced CO2 laser cutting machine and traditional processing means in the metal processing market, and has become the mainstream equipment in sheet metal processing. What is the difference between fiber laser cutting machine and CO2 laser cutting machine, and what are the advantages?
CO2 laser cutting machine, the gas is the medium that produces the laser beam, transmits the beam through the reflector. Instead of passing a beam through a mirror, a fiber laser works by means of a diode and a fiber optic cable, which pumps a laser beam through a flexible fiber optic cable to the cutting head. The maintenance cost is high, the front mirror and tail mirror are expensive, the life of turbine bearings is short, and the replacement cost is large.
Due to different laser transmission structures, the same power fiber laser cutting machine is more compact than CO2 laser cutting machine in appearance size, thus saving plant space. Fiber laser cutting machine maintenance free, basically no supplies, and can be qualified for harsh working environment, dust, shock, impact, humidity, temperature has a high tolerance.
With fiber laser's complete solid state digital module, a single design, fiber laser cutting machine has higher electro-optic conversion efficiency than carbon dioxide laser cutting. Each power unit of CO2 laser cutting machine, the actual general utilization rate is about 8% to 10%, and fiber laser cutting machine, this value is about 25% to 30%, fiber laser cutting system overall consumption of energy is about 3 to 5 times less than the carbon dioxide cutting system, making the energy efficiency increased to more than 86%.
The structure of CO2 laser is complex, the maintenance cost is high, and the beam divergence is large in the processing, so it is not suitable for large surface processing. Although the cutting seam is relatively thin, the speed is very slow when machining thick plates. Fiber laser cutting machine laser features in miniaturization, intensification, high brightness and high conversion rate, in the thin plate processing, the same power fiber laser cutting machine is 2-3 times higher than the cutting speed of CO2, smooth cutting section.
Fiber lasers have short wavelengths, which improve the absorption of light beams by cutting materials, and make it possible to cut non-conductive materials such as brass and copper. When cutting material up to 6mm thick, the cutting speed of the 1.5kW fiber laser cutting machine is equivalent to that of the 3kW carbon dioxide laser cutting machine.
CO2 laser cutting machine uses gas as the luminous medium. Because of the purity of CO2 gas, the resonator will be polluted, and it needs to be cleaned regularly. The mirror needs to be maintained and calibrated, so the daily maintenance workload is greater. This would cost at least $20,000 a year for a kilowatt-grade CO2 laser cutter. In general, fiber laser cutting is more environmentally friendly and convenient in the daily maintenance of equipment.
