With the gradual maturity of domestic lasers, the price monopoly of imported lasers has been broken. Now the manufacturers of domestic laser cutting machines are also gradually increasing with the price reduction, which also means that the domestic demand for laser cutting machines is growing.
The characteristics of laser cutting machine for flexible metal processing have been recognized by many sheet metal customers. Compared with traditional processing equipment, its cutting speed has great advantages. Speed is fundamental to efficiency, so how can we improve the cutting speed and use efficiency in the process of use? Now let's analyze the high-energy laser.
First, we need to understand several factors that affect cutting speed:
1. Different materials
The metal materials cut by laser cutting machine are mainly divided into aluminum plate, stainless steel, carbon steel, copper plate and alloy materials. Different materials have different characteristics and different laser absorption, so the cutting speed is different for materials with the same thickness.
2. Different thickness
Different material thicknesses require different piercing times. In the cutting process, the thicker the material, the greater the laser energy required, and the slower the cutting speed.
3. Different output power
Power is the most important factor to determine the cutting speed. The higher the power, the greater the laser energy, and the faster the cutting speed of thin plates. Take the following different powers as examples, you can compare the cutting speed of different materials with different powers;
a. The maximum cutting speed of 500W optical fiber laser cutting machine for different materials: the maximum speed of carbon steel is 13m/min; The maximum speed of stainless steel is 14m/min; The maximum speed of aluminum plate is 5.5m/min; The maximum speed of copper plate is 5.5m/min;
b. The maximum cutting speed of 1000W optical fiber laser cutting machine for different materials: the maximum speed of carbon steel is 24m/min; The maximum speed of stainless steel is 24m/min; The maximum speed of aluminum plate is 10m/min; The maximum speed of copper plate is 10m/min;
c. The maximum cutting speed of 2000W optical fiber laser cutting machine for different materials: the maximum speed of carbon steel is 28m/min; The maximum speed of stainless steel is 28m/min; The maximum speed of aluminum plate is 25m/min; The maximum speed of copper plate is 16m/min;
d. The maximum cutting speed of different materials of 3000W optical fiber laser cutting machine: the maximum speed of carbon steel is 35m/min; The maximum speed of stainless steel is 35m/min; The maximum speed of aluminum plate is 43m/min; The maximum speed of copper plate is 35m/min;
Scheme to increase the cutting speed of laser cutting machine
Adjust the laser machine parameters and improve the cutting speed of the machine.
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 properly, the cutting speed will not work. Parameters are just like the actions related to a series of actions such as driving, starting, accelerating, etc. If the parameters are not set properly, just like when the car is starting and you shift to a second gear to start, it will shake when starting. 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, just like the starting speed of a car in the process of driving. Many customers have such a misconception that the greater the initial speed, the better, but in fact this is wrong. If the initial speed of the laser machine is set too high, the machine jitter will be very large.
2. Acceleration: acceleration means the speed of the fuel filler valve during driving. It is the time from the initial speed to the normal cutting of the machine. When the machine is cutting different patterns, it is a stop start process. If the acceleration setting is too low, the machine will cut slowly.
