Now, fiber laser cutting machine with its processing speed, good cutting quality advantages, are widely used in various industries.Sheet metal processing industry is not only brought huge economic benefits to our enterprise, also bring convenience to our people's production and life.fiber laser cutting technology is developed with the development of sheet metal processing industry, plays an important role in promoting social production improvement.
Common processing materials of Fiber laser cutting machine have stainless steel, carbon steel, aluminum, copper, titanium, etc., and next we look at how these materials common processing ways are.
Carbon steel, fiber laser cutting machine with oxygen as gas processing, cutting edge will be mild oxidation.When the 4 mm in thickness plate may be using nitrogen as to high pressure gas cutting.In this case, the cutting edge will not be oxidized.More than 10 mm in thickness of plate, the plate laser cutting machine laser using special plate and work piece surface using oil in the processing can get good effect.
Copper and brass both material with high reflectivity and good thermal conductivity.Can use nitrogen gas cutting thickness 1 mm below the brass;Thickness of 2 mm below the copper can be cut, processing must use oxygen gas.Only the reflection absorption devices are installed on your system when cutting of copper and brass.Otherwise would destroy reflection optical components.
Stainless steel, stainless steel is one of the most used in the industries.Optical fiber laser cutting machine in cutting stainless steel, in the case of edge oxidation is not affected, the use of nitrogen gas to get the edge without oxidation without burr.The oil film in the plate surface coating will get better effect of perforation, and won't reduce the processing quality.
Aluminum, aluminum for optical fiber laser cutting machine, in spite of the high reflectivity and thermal conductivity, aluminum under 6 mm thickness can be cut, it depends on the alloy type and the laser power.When using oxygen cutting, cutting surface is rough and hard.With nitrogen, the cutting surface smooth.Because of its high purity pure aluminum is very difficult to cut, only in the optical fiber laser cutting machine "reflection absorption devices are installed on your system when cutting aluminum.Otherwise would destroy reflection optical components.
As we know, all kinds of materials in the process of machining, will be some problems more or less.So how to solve these problems, it makes the processing quality more secure?
Laser cut and apply the aluminium zinc plate, stainless steel work piece with burr this kind of situation, first of all depends on the condition of the burrs appears when cutting stainless steel, you can check the nozzle is to be replaced, guide rail movement is not stable, etc.But does not rule out cutting speed, cutting speed can sometimes lead to plank cut don't wear condition, this kind of situation especially when processing coated aluminium zinc plate.
Cut processing holes appear deformation, this is due to the machine tool in machining holes not adopt the method of blast hole, but with the method of pulse perforation.This makes the laser energy is too focused on a small area, will not processing areas also burned, form hole deformation, affect the processing quality.At this time should be in process lieutenant general pulse perforation mode to explosive perforation mode, to solve them.For low power laser cutting machine is on the contrary, should adopt the method of pulse perforation when small hole machining, to obtain a good surface finish.
Carbon steel when appear abnormal spark incision, this situation can affect the quality of parts cut section finish and processing.In other parameters under the condition of the normal at this time, should consider the following situation: laser nozzle NOZZEL loss, if the loss shall promptly replace the nozzle (in the case of no new nozzle to replace, should increase the cut operating gas pressure);At nozzle with laser connecting thread is loose, if loose should immediately stop cutting and superior thread again.
Fiber laser cutting machine material processing methods and the problem is different.Covers most of the metal fiber laser cutting machine for processing the materials, the problems arising from the cutting process are also different, specific to analysis according to the actual cutting conditions, and will feedback the problem to the factory in time, to do technical guidance.
