CNC also known as computer gongs, CNCCH or nc machine tool is actually Hong Kong there's a term, then was introduced into China, the pearl river delta is CNC milling machine, and in jiangsu area to be called 'CNC machining center' a kind of mechanical processing, is a new processing technology, main job is processing program, the original manual work to computer programming. Of course need a manual processing experience. CNC numerical control processing advantages 1, much less tooling number, processing complicated shape parts do not need complicated equipment. If you want to change the shape and size of the parts, only need to modify the parts processing procedures, apply to new product development and modification. 2, stable machining quality, high machining accuracy, high repeat precision, aircraft to meet the demand of the processing. 3, many varieties, small batch production situations production efficiency is high, can reduce the production preparation, machine tool adjustment and process the test of time, and due to the use of optimal cutting quantity and reduces the cutting time. 4, conventional methods is difficult to machining the complexity of surface, can even machining parts of some cannot be observed. 5, nc machine tools are the shortcomings of the equipment is expensive, require maintenance personnel with high level. Future works besides can provide users with 3 d printing services, also provides cavity after injection molding, silicone mold, and CNC processing and other services, including the main material has the following kinds: CNC machining aluminum alloy 6061 is 6061 aluminum alloy after heat treatment the pre-tension craft production of high quality aluminum alloy products, its strength is not compared with 2 or 7 XXX XXX department system, but its magnesium, silicon alloy properties. Material advantages: it has excellent processing performance, excellent welding characteristics and electroplating, good corrosion resistance, high toughness and processing after deformation, dense material without defects and easy polishing, coloring film easily, good features such as oxidation excellent results. 7075 aluminum alloy 7075 aluminum alloy is a kind of cold treatment forging alloy, high intensity, far more than mild steel. 7075 is one of the most powerful alloy commercial. Material advantages: the general corrosion resistance, good mechanical properties and anodic reaction. Fine grain make deep drilling performance better, tool wear resistance increase, more different thread rolling system. Pure copper (copper Also known as red copper) Is a kind of excellent toughness on the conductivity of the metal surface is a red rose. It is not pure copper, it contains 99. 9% copper, and other elements added to improve the surface and performance. Material advantages: it has good conductive, thermal conductivity, ductility, impact resistance and corrosion resistance. Electrical conductivity and thermal conductivity of copper is second only to silver, widely used in the production of conductive, thermal conductivity apparatus. Copper in the atmosphere, water, and some non oxidizing acid ( Hydrochloric acid, dilute sulphuric acid) And a variety of organic acid, alkali, salt solution ( Acetic acid, citric acid) Good corrosion resistance, used in the chemical industry. Good weldability, can made by cold, thermoplastic processing all kinds of semi-finished products and finished products. In the 1970 s, copper production more than the other the production of all kinds of copper alloy. Brass brass is copper zinc alloy, made up of copper, zinc, brass is called ordinary brass. Material advantages: its high strength, high hardness, strong resistance to chemical corrosion. It is also more prominent on the mechanical properties of the machining. Brass strong wear resistance. Special brass also called special brass, its high strength, high hardness, strong resistance to chemical corrosion. It is also more prominent on the mechanical properties of the machining. Draw by brass seamless copper tube, soft, strong wear resistance. 45 # steel 45 steel is a term in GB, also known as the 'oil', the steel has higher strength and better cutting processability. Material advantages: high strength and good workability, cutting can be obtained after proper heat plasticity and tenacity, wear resistance, convenient material source, for hydrogen welding and argon arc welding. 40 cr steel is introduced 40 cr steel grade of GB standard in China, 40 cr steel is one of the most widely used steel machinery manufacturing. Material advantage: has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. Steel hardenability is good, in addition to the conditioning treatment is suitable for the steel cyanide and high frequency quenching process. Good cutting performance. Introduction of Q235 steel Q235 steel is a kind of carbon structural steel, Q represents the yield strength of the steel grade. Usually, the steel after heat treatment not to use directly. Material advantage: with the increase of the thickness of the material and makes the yield value decreases, and because of the carbon is moderate, has good comprehensive performance, strength, plasticity and welding performance is good, the most widely use. SUS304 steel SUS304 refers to 304 stainless steel, has the processing performance is good, the characteristics of high toughness. Material advantages: it has good corrosion resistance, heat resistance, corrosion resistance, low temperature strength and mechanical properties, punching bending such as hot workability is good, no heat treatment hardening phenomenon, non-magnetic.
