Laser marking and laser etching are ending up being increasingly more important in a growing number of industries. The fundamental needs to laser marking or laser engrave your products include:
oThe mark is exceptionally resilient, long-term and for the most parts can not be gotten rid of without ruining the product itself, this is true for laser marking, laser etching, or laser annealing.
oThe laser marking process is precise, 100% repeatable, fast, with really clear sharp results.
oThe laser mark or laser etch can rapidly and quickly be changed without any maker modification over, and, without replacing any tools. The altering of a laser marking or laser engrave is an easy drag and click computer system operation.
oThe laser requires no consumables and no additional purchases of included materials or products. For that reason the operating and maintenance costs of owning and running the laser marking or laser etching system are practically non existent.
The word laser is an acronym for light amplification by simulated emission of radiation. The laser beam is formed in a sealed tube with an electrode set, laser gas, and electrical discharge. The beam is emitted into a telescope which broadens the laser beam from a size of roughly 2mm as the beam exits the laser tube as much as 7mm to 14 mm for many laser marking or laser etching operations. The expanded beam is directed into a laser head consisting of 2 mirrors located on high speed galvo motors. The laser beam is directed off the mirrors though a single component flat field lens to the item being laser marked or engraved.
Usually the laser marking or laser etching fields developed variety in size from 65mm x 65mm [2.5" x 2.5"] at the smallest size to 356mm x 356mm [14.0" x14.0"] square at the biggest. The next factor to consider is the laser beam area size. This is the size of the focused laser light energy at the laser marking or laser etching point on the item and can vary from roughly 200 micron [micrometers] or.0078" at the smallest to roughly 540 microns or.021" for Co2 lasers. The laser beam spot size ranges from approximately 20 microns or.0007" at the smallest to approximately 70 microns or.0027" at the largest for Nd: YAG lasers. These small spot sizes and extremely focused laser light energy create the comprehensive, clear, irreversible marking that is common of the laser marking or laser etching procedure.
Controlling Lasers and Laser Marking Options
Laser markers and laser etchers are controlled via software application. Several variables need to be controlled:
1. Laser power as determined in watts
2. Frequency, indicating the pulse frequency of the laser beam
3. Inches per 2nd, indicating the speed that the beam steering mirrors are moving
Figuring out the right setting for the laser is the single most important and important component in the success or failure of the laser marking procedure. When the proper settings have been figured out and demonstrated a 100% repeatable laser mark can be attained.
Laser controller software application is accessed by means of a PCI interface card. This sends out the digital signals of the computer based marking or engraving files to the motors and directs the laser beam to the product being laser marked or laser engraved.
There are several different types of laser marking and laser etching and a number of different considerations in terms of visual results for the laser mark or laser engrave.
The laser beam is formed in a sealed tube with an electrode set, laser gas, and electrical discharge. The beam is emitted into a telescope which broadens the laser beam from a size of around 2mm as the beam exits the laser tube up to 7mm to 14 mm for most laser marking or laser etching operations. The laser beam is directed off the mirrors though a single element flat field lens to the product being laser marked or engraved.
The laser beam area size varies from approximately 20 microns or.0007" at the smallest to around 70 microns or.0027" at the biggest for Nd: YAG lasers. These little spot sizes and highly focused laser light energy create the in-depth, clear, irreversible marking that is typical of the laser marking or laser etching procedure.
