The world is more colorful because of science and technology, and life is richer because of science and technology. With the rapid development of science and technology, the world is changing at an unprecedented speed and in an unprecedented way... More and more new technologies and products of aluminium alloy parts processing emerge, which promotes the rapid development of various industries and changes people's lives.
Aluminum alloy parts are popular because of their light weight and exquisite appearance. They are widely used in industry and daily necessities. Especially in recent years, with the development of science and technology, social progress, people's demand for product diversity is growing. Therefore, the processing technology of aluminium alloy parts will be more and more concerned by people. CNC machining is one of the common processing methods of aluminum alloy precision parts.
Aluminum alloy parts have excellent processing performance, good appearance, metal aesthetic feeling and abundant surface treatment means, so they are loved by all walks of life. The surface treatment forms of aluminum alloy parts mainly include sandblasting, polishing, wire drawing, electroplating, spraying, oil filling, etc.
Sand blasting is a process of cleaning and roughening metal surface by using the impact of high-speed sand flow. This method of surface treatment of aluminium parts can make the surface of the workpiece get a certain degree of cleanliness and different roughness, improve the mechanical properties of the workpiece surface, improve the fatigue resistance of the workpiece, increase the adhesion between the matrix and the coating, prolong the durability of the coating film, which is more conducive to the leveling and decoration of the coating.
Polishing process is to reduce the surface roughness of workpiece by mechanical, chemical or electrochemical methods, so as to obtain a bright, flat surface processing method. Polishing technology is mainly divided into: mechanical polishing, chemical polishing, electrolytic polishing. Aluminum alloy parts with mechanical polishing and electrolytic polishing can approach the mirror effect of stainless steel, giving people a sense of high-grade, simple, fashionable future.
Aluminum alloy wire drawing is a process of repeatedly scraping out the lines of aluminium sheet with sandpaper. Drawing can be divided into straight wire drawing, screwed wire drawing, screwed wire drawing, screwed wire drawing. Aluminum alloy wire drawing process can clearly show each fine trace, so that the metal matte gloss in the exudation of fine silk luster, products both fashionable and technological sense.
High-light cutting technology is to use an engraving machine to reinforce the diamond knife on the spindle of a high-speed engraving machine (general speed is 2000 rpm) to cut parts, and produce a local bright area on the surface of the product. The brightness of cutting highlight is affected by the speed of the milling bit. The faster the bit speed is, the brighter the cutting highlight is. On the contrary, the darker the cutting highlight is and the easier the cutter grain is. In recent years, some metal frames of high-end TV sets adopt high-light milling technology. In addition, anodic oxidation and wire drawing technology make TV sets full of fashion sense and sharp sense of science and technology.
Anodic oxidation refers to the electrochemical oxidation of metals or alloys. Under the corresponding electrolyte and specific technological conditions, aluminum alloy parts form an oxide film on the aluminium products (anodes) due to the action of applied current. Anodic oxidation can not only solve the defects of surface hardness and wear resistance of aluminium, but also prolong the service life of aluminium and enhance its beauty. It has become an indispensable part of surface treatment of aluminium. It is a widely used and very successful process at present.
Dual-color anodization refers to the process of anodizing a product and giving different colors to a specific area. Dual-color anodic oxidation has complex process and high cost, but through the contrast between the two colors, it can better reflect the product's high-end and unique appearance.
Surface treatment is often used after CNC processing of aluminium alloy parts. With the continuous expansion of the application scope of aluminium alloy parts, the requirements for their surface quality are getting higher and higher. This requires manufacturers of CNC processing and surface treatment of aluminium alloy parts to be down-to-earth, improve technical level, improve process and reduce costs. Only in this way can we grasp the voice and dominance in the market of aluminium alloy parts processing group. Otherwise, the so-called market share will always be a castle in the air and can not withstand a blow.
