Answers To The Common Problems Of Laser Cutting Machine
Here, you can find solutions to the common problems of laser cutting machine and laser cutting process.
What is the working principle of laser cutting machine?
Laser cutting machine is used to illuminate the workpiece with high power density laser beam,to make the workpiece rapidly melt, vaporize, abate or reach the point of ignition,
at the same time, the molten material is blown out by the high-speed airflow which is coaxial with the beam to the workpiece,
through moving light spot position by the CNC mechanical system to cut workpiece.
Which factors could effect the precision of laser cutting machine?
The equipment itself can affect the laser cutting accuracy, some factors
such as mechanical system precision, table vibration level, laser beam quality, auxiliary gas, nozzle etc, some factors are inherent material factors,
such as the physical and chemical properties of materials , the reflectivity of the material, etc.
Other factors like adjust parameters based on the specific processing object and the user’s quality requirements,
such as output power, focal position, cutting speed, auxiliary gas etc.
How to find the focal position of laser cutting machine ?
Laser power density has a great influence on the cutting speed,
so the selection of the focal position is particularly important.
The spot size of the laser beam is proportional to the length of the lens.
There are three simple ways to find the cutting focus position in the industrial files:
1.Pulse method: Let laser beam print on a plastic sheet,moving the laser head from top to bottom,checking all holes and the smallest diameter is the focus.
2.Slant plate method: Using a slant plate under the vertical axis, moving it horizontally and looking for the laser beam at the minimum focus.
3.Blue Spark: Remove the nozzle, blow the air, pulse on stainless steel plate, move the laser head from top to bottom, until find the blue spark as the focus.
At present, many manufacturers’ machines have automatic focus.
Automatic focus can significantly improve the laser cutting machine’ efficiency, reduce piercing time on thick plate
So the laser cutting machine can adjust automatically to find the focus position based on different materials and thickness.
What’s the application range of laser cutting machines?
Laser cutting machine has high speed, narrow width, good cutting quality, small heat affecting area and good flexible processing,
so it is widely apply for automobile manufacturing, kitchen industry, sheet metal processing, advertising industry, machinery manufacturing,
cabinet processing, elevator manufacturing, fitness equipment and other industries.
