The Complete Guide to Cutting Lasers and Laser Cutting Techniques

What is a Laser Cutter? A laser cutter is a machine used to cut materials using lasers. The device creates an intense beam of light which is directed at the material to be cut. The laser cutter can work with almost any material, but it works best on metal. — A laser cutter is a machine that uses a laser beam to cut material. The most common use of a laser cutter is to cut paper, card, vinyl and most plastics. A laser cutter is similar to an inkjet printer in the sense that they both use a computer to generate the image on the material. A laser printer has an optical system for deflecting an image from one surface onto another while a laser cutter does this with a single beam of light. What is a Laser Cutter’s Purpose? Laser cutters are widely used in industrial design, architecture, and electronics. They are also used for many personal projects. They are mainly utilized to cut large sheets of material like acrylic, wood, metal, and paper. The laser beam is controlled by a computer-aided cutting interface to produce intricate shapes with accuracy and precision. — Laser cutters are CNC machines that use a laser beam to slice materials across the surface. The purpose of laser cutters is to create accurate, repetitive, and clean edges with little to no heat distribution on the material surface. This is done by using a laser beam, which can be steered around an object’s shape and

Anodized Aluminum, how to anodize aluminum?

What is anodizing aluminum? Generally speaking, aluminum or aluminum alloy is used as the anode for the anode, and the lead plate is selected for the cathode. The aluminum and lead plate are placed together in the aqueous solution. There are sulfuric acid, oxalic acid, chromic acid, etc., for electrolysis. An oxide film is formed on the surface. If anodizing is not specified, it usually refers to sulfuric acid anodizing. Anodizing Aluminum is accomplished by immersing the aluminum into an acid electrolyte bath and passing an electric current through the medium. A cathode is mounted to the inside of the anodizing tank; the aluminum acts as an anode, so that oxygen ions are released from the electrolyte to combine with the aluminum atoms at the surface of the part being anodized. Anodizing is, therefore, a matter of highly controlled oxidation the enhancement of a naturally occurring phenomenon. Sources: https://www.anodizing.org/page/what-is-anodizing  Why do aluminum alloys need to be anodized?

What Are The Surface Treatments Of Aluminum Alloy? Aluminum Alloy is easy to do surface treatment to Solve or improve the performance of materials in three aspects: anti-corrosion, decoration and functionality, Common aluminum alloy surface treatments include electroplating, spraying, wire drawing, anode, sandblasting, passivation, polishing, oxide film treatment, etc. (1) Sandblasting: The main function is surface cleaning. Sandblasting before painting (painting or plastic spraying) can increase the surface roughness and contribute to the improvement of adhesion. (2) Passivation: It is a method to transform the metal surface into a state that is not easy to be oxidized, and to delay the corrosion rate of the metal. (3) Coloring: There are two main processes for coloring aluminum: one is aluminum oxidation coloring process, and the other is aluminum electrophoresis coloring process. (4) Chemical polishing: A chemical processing method that uses the selective self-dissolution of aluminum and aluminum alloys in acid or alkaline electrolyte solutions to level and polish the surface of the year to reduce the surface roughness and PH. (5) Chemical oxidation: The oxide film is thin, with a thickness of about 0.5-4 microns, and is porous, soft, and has good adsorption properties. It can be used as the bottom layer of organic coatings, but its wear resistance and corrosion resistance are not as good as anodized film (6) Spraying: The external protection and decoration
