As we know there are numerous wavelength lasers that can be employed for marking/engraving. The predominant kinds are CO2 and YAG lasers. These wavelengths stretch the spectrum from far infrared to close to infrared. The decision as to which laser sort to use is really primarily based on the substance becoming marked.

For this post, we are likely to concentrate on Yb: Fiber lasers that selection from 1060 to 1070 nanometers. These are most often used for marking metals, achieving contrast on specific plastics and paint/ink removing. As the laser resources are basically the identical among galvo and flatbed units, the actual beam delivery system is the crucial determination position.

Initial a swift definition of each kind is warranted. Galvo is small for "galvanometer " which is a high speed, substantial precision motor that is used to immediate the beam to a area in space. The phrase "steered beam" is typically used as a descriptor for this sort of laser. Mirrors are mounted to the end of two impartial galvo motors and quite quick deflection of the two mirrors doing work in tandem will cover an area with the targeted beam. Special optics referred to as "flat field" lenses allows the beam to be sent perpendicular to the perform piece more than a offered spot. The most typical area dimensions are 4" sq (five.5" diameter) and 7" sq, or 8" diameter. Generally talking the marking top quality is about the identical across the whole discipline.

Flatbed lasers, also acknowledged as "gantry" lasers supply the beam through a XY plotter system most usually driven by AC or DC servo motors. This is a delivery variety more common to CO2 lasers but is turning out to be widely used with Yb: Fiber lasers and YVO4 Vanadate lasers. The mixture of the servo motors and belt driven gantry arms allows for large location to be covered. There are numerous gantry sort Fiber lasers that permit areas as big as 24" x 36" to be tackled. Based on the plotter fashion of shipping the beam is focused through the heart a basic lens and down on to the perform piece. The XY axis then moves the centered beam all around the marking region in a linear movement (generally in raster style).

So why is one much better than an additional? In fact, you can't say 1 is much better with no making use of the true program or approach as the driving indicator. I have experienced the chance to function for organizations who deliver equally kinds. This both a blessing and curse from a salesman's point of view. Most firms who manufacture a flatbed technique do not have the expertise or expertise to put out a aggressive galvo device. On the other hand, it is good to have every technologies to drop back on.

So perhaps the initial rule of thumb is to contemplate what the vendor's important products are. If they make flatbeds, rotary engraver, percussion stampers and so on...galvo lasers are most likely not their principal problem. I operate for Electrox, who does absolutely nothing but make steered beam, laser marking systems. There are numerous other organizations who function in the very same style, exactly where galvos are their specialty. Also, there are a variety of organizations in which flatbed lasers are their bread and butter. In choosing the technology, take into account the expertise base of the provider.

If cycle time is not the main problem, I recommend obtaining samples processed for analysis by the two systems. Getting marked areas that you can examine side by aspect, with different laser types is a luxury that 1 ought to not move up. If speed of the mark is the key, galvo methods are the only way to go. If your components are extremely significant, the flatbed system could be preferable however most galvo suppliers provide a programmable XY table option. Evaluate the pricing and the top quality of the marks if this is your predicament.

Galvos are considerably greater if the marking is planning to be "inline", i.e. on a automatic manufacturing line. Most flatbeds are not suited for customization. Flatbeds, even though slower in processing speed really occasionally generate far more generation when you are working in batch mode. Batch mode is when you lay like components out in a matrix and then process them in a rows and columns format. The comparatively gradual speed of the flatbeds normally will enable the operator to conduct other operations in parallel with the marking. A trace is to question your vendor to offer a time research dependent on your precise manufacturing demands.

Fiber lasers, I am speaking of the genuine "engine" of the technique, are really reliable and extended long lasting. Galvo techniques require less upkeep that flatbeds, but this is nominal for possibly. The lengthier stroke of the gantry types does create circumstances in which belts need to have to be modified and alignment is more crucial. Even now this is a really easy procedure and normally not an problem in manufacturing.

Flatbed techniques generally work off of a more graphic oriented program such as CorelDraw. So if you are doing a good deal of graphic manipulation, logos, images this might be the far better selection. If you are interested in variable text such as bar coding, serialization, and date coding the galvo systems are generally remarkable. Often inquire for a demo of the software package when selecting a laser. Be aware: I even wrote an before article about choosing laser marking software program. Simplicity of use is key.

The variety of the tools is something that you will have to reside with for some time, so it is mission vital that you evaluate all the alternatives. Make sure that you realize what you will be employing the laser for now and what you might need to have it for in the future. We as manufacturers can't make machines greater, faster and simpler to use right after the reality, so make positive you acquire gear that can develop with you as your company expands.

So in conclusion, in no way buy strictly on value. Take into account all of the overall performance characteristics of every sort of beam shipping and delivery technique and most importantly which kind will be the biggest advantage to you and your business.
