Laser cutting machine
is an important equipment for sheet metal processing, and the correct use of laser cutting machine is also an important prerequisite to improve its service life.Therefore, after the purchase of the machine, must master the specification, the specification of the machine operation process and method, in order to reduce the failure rate, improve the service life.Here we will introduce the standard and standardized operation process of laser cutting machine:
Standard operating procedure for laser cutting machines
First of all, strictly abide by the rules, follow the laser cutting machine equipment start, shut down, etc., shall not be forced to shut down or open;
Second, employees are not trained to operate machines.Only after being fully trained can they operate the machine;
Third, in the process of work, the laser cutting machine outside personnel should not be close to the operating platform and console, the core operation link must be completed by professionals;
Fourth, adjust the optical path of the machine tool, adjust the cutting head in the way of tracking, and force the tracking of accurate control process, to ensure the safety of human and machine;
Fifthly, every time the machine is turned on, it must go back to the reference point, check and deal with the focusing lens, calibrate the coaxiality of the beam nozzle, open the auxiliary gas for cutting, and the pressure in the bottle should not be less than 1 MPa;
Sixth, check the performance of external optical circuit to ensure gas, cold circuit cabinet, cooling river circuit, air compressor and cold dryer.The laser cutting machine drains the water from the filter once a week.
There are three simple ways to identify an industry's cutting priorities:
1. Printing method: make the cutting head move from top to bottom, print with laser beam in the length of plastic plate, and focus on the minimum printing diameter.
2. Tilt plate method: Use the plastic plate placed at an Angle with the vertical axis to pull out horizontally and find out the minimum position of laser beam as the focus.
3. Blue spark method: take out the nozzle, blow the air and hit the pulse laser on the stainless steel plate, making the cutting head move from top to bottom until the largest blue spark becomes the focus.
What is the application scope of laser cutting machine?
Laser cutting machine is widely used in automobile manufacturing, kitchenware industry, sheet metal processing, advertising, machinery manufacturing, chassis manufacturing, elevator manufacturing, fitness equipment and other industries, with a wide range of cutting, cutting speed, cutting slit narrow, cutting quality, small thermal impact area, processing flexibility and other advantages.
What is the cutting thickness of the laser cutting machine?
At present, cutting thickness laser cutting machine is generally less than 25 mm.Compared with other cutting methods, this method has obvious advantages in cutting materials whose size is less than 20 mm.However, if accurate safety control methods are not followed, personal injury or machine damage can also be caused to users.
At present, many manufacturers of machines have achieved automatic focus.Among them, high-power CO2 laser and YAG laser have been widely used in secret processing. Fiber laser based on fiber array has significant advantages in reducing threshold, oscillation wavelength range, tunable wavelength and other aspects, and has become a new technology in the laser field.
The processing efficiency of laser cutting machine
can be improved obviously by using automatic focusing function: the perforation time of thick plate can be shortened greatly;The focus can be automatically adjusted to the most appropriate position when machining parts of different materials and thicknesses.
Be careful of flammable materials when using the machine.
What is the type of laser and what are the differences between them?
At present, CO2 laser, YAG laser and fiber laser are mainly used in laser processing and manufacturing.Compared with ion cutting and oxygen cutting, laser cutting produces less dust, weak light and low noise.
What are the factors that affect accuracy?
There are many factors affecting the laser cutting precision, some of which are determined by the equipment itself, such as the precision of the mechanical system, the impact degree of the table, the quality of the laser beam, the influence of auxiliary gas and nozzle, etc.Some of these factors are intrinsic factors of the material, such as physical and chemical properties of the material, reflectivity of the material, etc.Some factors are selected based on detailed machining objects and user quality requirements, and adjustments are made accordingly to determine relevant parameters, such as output power, focusing position, cutting speed and auxiliary gas.
During the operation of the machine, the operator shall not leave without authorization to avoid unnecessary losses.The spot size after laser beam extraction is proportional to the focal length of the lens.
How does the laser cutter work?
Laser cutting is a kind of thermal cutting method that USES a focused high power density laser beam to irradiate the workpiece, melt, evaporate, flake or reach the combustion point of the material in the irradiation area, blow out the fused material through the high-speed airflow and the beam coaxiality, and move the spot irradiation position through the CNC mechanical system to cut the workpiece.
Do not store explosive or flammable materials in laser processing areas.Do not observe the laser through binoculars, microscopes, magnifying glasses, etc.Laser cutting machine, including foam core materials, any PVC materials, high reflective materials, etc.
How do I find the focus of a laser cutter?
Because the laser power density has a great influence on the cutting speed, the choice of focusing position is particularly important.
