What are the advantages of CNC fiber laser cutting machine tube?More and more enterprises began to use CNC fiber laser cutting machine tube round hole, because of the flexibility of laser processing and high efficiency.Dahan laser air speed of 75 meters per minute is enough to meet the needs of many sheet metal processing plants for high speed, in addition, laser processing of the round hole section is more smooth, the diameter of the round hole can also be infinite modification, to meet the diversified needs of the factory.
However, using fiber laser cutting machine tube machining round hole is not very simple, but needs some skills.The following let the Han laser craftsmen on the problem of cutting round hole to give you analysis of the reasons and matters needing attention.
The blow pressure is not suitable
In the process of blowing, when the pressure is too small, there will be edge scraping slag, carbonization phenomenon, too large pressure and easy to blast hole.Therefore, this requires the perfect cooperation between the process proofing division and the machine, and the choice of appropriate air pressure based on experience, so as to make the round hole cut more full.
The hole is too small
CNC fiber laser cutting machine cutting round hole is the best solution of the round hole ratio 1:1, that is to say the aperture and the plate thickness of the ratio of 1:1, of course, this proportion, that is to say the larger the aperture, cutting out high quality round hole more easily.Otherwise, when the energy of the fiber laser cutting machine is insufficient, the cutting hole is easy to leave the residual breakpoint and the phenomenon that the round hole is not round.
Servo motor parameters are wrong:
Sometimes the ellipse or irregular phenomenon will appear in the circular hole, which is related to the motion mismatch of the X\IY axis, and the direct reason for the motion mismatch of the XIY axis is the improper adjustment of servo motor parameters.So cutting round hole quality, servo motor also has certain requirements.
Precision error of guide rail and lead screw
If the parameter error of servo motor affects the cutting quality, then the precision error of guide rail and lead screw will directly lead to the accuracy of the circular hole can not reach the expected.This is related to the strength of laser cutting machine manufacturers, usually, some small factories will cheat customers that laser cutting machine precision can reach 0.1mm, but in fact, in the actual operation process, will make the laser drilling quality and effect are not good, affect the added value of products.So it is very necessary to choose high quality and large brand laser cutting machine.
1, high cutting accuracy: laser cutting machine positioning accuracy of 0.05mm, repeat positioning accuracy of 0.03mm.
2, laser cutting machine slitting narrow: laser beam focus into a small point of light, so that the focus at a high power density, the material is soon heated to the degree of gasification, evaporation formation of holes.With the relative linear movement of the light beam and the material, the hole is continuously formed with a very narrow cut width, and the width of the cut is generally 0.10-0.20mm.
3, laser cutting machine cutting surface smooth: cutting surface without burr, notch surface roughness is generally controlled within RA6.5.
4, laser cutting machine speed: cutting speed up to 10m/min1 large positioning speed up to 30m/min faster than the speed of wire cutting.
5, laser cutting machine cutting quality is good: no contact cutting, cutting edge thermal influence is very small, basically no thermal deformation of the workpiece, completely avoid the formation of material edge collapse, single drive fiber laser cutting machine recommended, cutting generally do not need two processing.
6, no damage to the workpiece: laser cutting 1 head will not contact with the surface of the material, to ensure that no scratch workpiece.
7, not affected by the shape of the workpiece: laser processing flexibility is good, can process any graphics, can cut pipe and other profiles.
8, laser cutting machine can cut a variety of materials: such as plastic, wood, PVC leather, textiles, plexiglass and so on.
9, save mold investment: laser processing does not need the mold, no mold consumption, no need to repair the mold, save the time to replace the mold, thus saving the processing cost, reduce the production cost, especially suitable for the processing of large products.
10, save materials: the use of computer programming, can cut different shapes of products, 1 to maximize the utilization of materials.
11. Improve the delivery speed of samples: after the formation of product drawings, laser processing can be carried out immediately, and new products can be obtained in a short period of time.
12, safety and environmental protection: laser processing waste less, low noise, clean, safe, pollution-free, greatly improve the working environment.
