This structured surface reduces the amount of light that is reflected, and the result is a deep, matt blackening of the marking, which appears the same when viewed from any angle. At Sine-tific Solutions, we have state-of-the-art 4th axis machining capability that produces metal engraving with accuracy and speed. A beam of concentration from a fiber laser engraver interacts with the metal’s surface, and it changes the metal’s appearance and properties. Our metal engraving capabilities can handle a large variety of custom products, including: Engraved nameplates. Laser marking is a permanent process that creates a lasting mark on metal. In this regard, you have to keep in mind the different settings as well as the equipment and methodology that you need to apply for the best results. However, metal laser engraving is a vast field with several considerations for various cases. Type Of Engraving Machines: CNC Engraving Machines.
#Metal engraving serial
03 mm deep in the metal surface.īlack marking is a marking process that produces very high-contrast, dark markings. You can use fiber laser engravers for marking parts or serial numbers, ID codes, barcodes, and graphics. Metal engraving is extremely useful for both commercial and personal purposes.

Mild Steel 3D Metal CNC Engraving Machine, Automation Grade: Semi-Automatic. The colour change is achieved through localised material heating only. The material surface remains even during annealing because nothing is removed from it.
The colour depends on the temperature of the heated layers. The oxide layer is black most of the time, but it can also have other annealing colours. steels and titanium, but not aluminium or non-ferrous metals. You can only anneal metals that change colour when under the influence of heat and oxygen, i.e. It is also the preferred method whenever a precision fit is required or there is a need to avoid material bulging. This generates oxide layers on the surface of the workpiece which are associated with metallic annealing colours. Annealing heats the material locally to just below its melting point.
