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:  Why do aluminum alloys need to be anodized? As one of the most popular and widely used metal material, aluminum is good for CNC Machining and it is always the top choice for engineering designer, but most of aluminum machined parts require surface treatment and the best recommendation is anodizing, but why aluminum parts needs to be anodized?
