laser cutting aluminum problemsPosted by: | Posted on: November 27, 2020
In addition, pulse perforation requires a more reliable pneumatic control system to achieve gas type, gas pressure switching and perforation time control. At Mainstay, we invested in a Trumpf Fiber Optic Laser Cutting Machine with BrightLine Fiber function. When cutting thicker materials, cutting speed slows, and cut quality lessens. In this case, if no problems with other parameters, the following cases should be considered: This is because the pulse perforation is used when machining small holes with high power laser cutting machine, which causes the laser energy concentrated in a small area, resulting in burnt of non-processed area and deformation of the hole. Because of this, reflective metals do not pose the same threat of damaging fiber laser cutters that they do CO2 cutters. I have a CNC router but it is really not designed for cutting aluminum and would be too slow. In this case, change the pulse perforation (soft puncture) method to blasting perforation (normal puncture) in the processing program.

In photo etching, dimensional tolerances are +/-15% of material thickness. Based in Indianapolis, Indiana, IMH Products aims to set the standard for modern manufacturing partnerships by persistently increasing efficiency and investing in innovative equipment and processes. By definition, laser cutting is a process of melting the material in its path, so the work piece will be subjected to high temperatures. Laser technology has several unique attributes that affect the quality of its cuts. On laser cutters, the beam width is determined primarily by the optics. This will often automatically stop the laser, before any major damage is caused. Thomas RegisterÂ® and AS9100 Rev D | ISO9001 and ITAR Registered. Our General Manager, Art Long, has worked in this industry for more than 30 years and is well familiar with the challenges of etching aluminum. Hardening can be useful for many applications because it increases product durability, but it also limits the amount of machining that can be done, making post-cut threading or deburring difficult. This means that should the laser beam be reflected by the flat sheet it can be transmitted back through the beam delivery optics, and into the laser itself, potentially causing significant damage. In this case, stop the cutting quickly, check the connection state and screw the thread tightly. The laser cutting linear speed is too fast, reduce the linear speed; The nozzle sensing is not allowed to lead to the laser focus position. A possible solution for laser cut aluminum and laser cut steel, involves the use of a higher power setting coupled with compressed gas technology. This post will summarize some solutions to the common problems in metal laser cutting. Fiber Optic Lasers (“fiber lasers”) are the most advanced laser cutting technology today. These machines are highly effective in cutting various grades of steel, such as stainless and carbon steel. This system usually takes the form of a back reflection system which can detect if too much laser radiation is being reflected back through the optics. Of course this will have effect on the dross. In this case, comprehensive consideration should be given to other factors of the machine tool, such as whether the nozzle should be replaced, the rail movement is unstable, etc. Although Nd:YAG lasers are usually incapable of cutting steel at any thickness approaching 20 millimeters, an optical fiber enhancement with an oxygen assist gas mechanism can enable these crystal-based systems to cut thicker steel workpieces.
