CNC machining is the most commonly used subtractive production technique. In this type of manufacturing process, the material is ejected from a solid mass of material using different types of cutting tools to come up with a part based on a computer-aided design model. You have to begin with an oversized material piece which you have to cut away so that you are left with the bit you want. The simple similarity is designing a chunk out of the material. You get to chip away the marble until you come up with a masterpiece.
This production procedure can be used in the machining of plastics and metals. CNC machining, which also stands for computer numerical control machining involves the programming of computer software to give out automated commands to the functioning of the manufacturing equipment. Different intricate machinery can be operated using this machining method. The other good thing about this procedure is that it ensures three-dimensional cuttings are completed with a series of commands.
CNC machining supersedes the restraints that come with standard machining procedures. Engineers who operate machines must issue out directions using computers and direct the cue of the machining equipment or any other tool that is involved. The different software used in this method ensures the whole process is successful. The two common types of machining system used include milling and turning.
In the CNC milling procedure, a part is firmly fixed onto the surface, and the material is removed using revolving cutting equipment. When it comes to turning, the piece is firmly set on a revolving chuck, and the material is removed using stationary cutting equipment. The different materials that can be produced through CNC machining include brass, aluminum, stainless steel, and nylon.
Aluminum CNC Machining
Aluminum is one of the most commonly machined materials because of its wonderful mechanical features. Some of the features include softness, affordability, durability, and its ability to resist corrosion. Over the recent days, precisely machined CNC aluminum parts have become common especially in the military, medical, aerospace, and industrial engineering. Advanced technologies and CNC machines are the ones used for CNC aluminum because they require accuracy.
One good thing about aluminum is that is a versatile material which can be put to use in various areas. It has outstanding features like being light and durable. Aluminum also requires absolute brilliance so that it can be applied to different fields as broad as the production of aircraft, power generation and in the car manufacturing industry. In the car production industry, it can be used in the manufacturing of reflectors that are usually used in car lamps.
CNC aluminum parts are usually less expensive because they can be machined within a short period compared to other metals like steel. They also do not need extra finishes. Small quantities of zinc, magnesium, copper and other materials are added for strength because the pure aluminum metal is usually soft. When exposed to the atmosphere, a thin protective layer is formed which makes it resistant to corrosion and reduces the chances of it catching rust on the surface. It is resistant to chemicals, easy machining capabilities, and also has a lot of strength compared to its weight.
Aluminum weighs about a third as much as steel. It also conducts heat and electricity easily which makes it the perfect material for steel sinks. Aluminum reflects heat and light, is malleable and non-magnetic. Some companies specialize in the production of custom CNC aluminum parts. This is mostly because they are economical and lightweight. Aluminum CNC parts are usually less expensive because they can be machined within a short period compared to other materials like brass and steel. It does not also require new finishes.
Benefits of CNC Aluminum Parts
There are a couple of benefits that come with the CNC machining of aluminum. They include:
1. Easily Bendable
One good thing about the use of the CNC machining process to come up with aluminum CNC parts is that they can be bent easily. Unlike steel, the aluminum material can be turned with ease during the machining procedure, because the thickness of this material can make proper use of the various molding methods. It can be achieved best by pressing, and processing to attain a variety of shapes of the aluminum CNC parts easily.
2. Easy Machining
The other good thing about the aluminum CNC machining process is that materials can easily be manufactured through punching, folding and drilling. You can use it to form various shapes of the parts as they are needed. The energy used in the machining of aluminum is much lower compared to that which is used in steel.
3. Resistant to Low Temperatures
Aluminum materials are resistant to low temperatures. We all know how steel can be delicate especially in the welding section or an environment with low temperatures. Aluminum materials can be easily machined under low temperatures compared to the steel material.
4. Custom Finishing
Aluminum can be customized to meet the client's requirements after finishing. You can do a couple of things to give it the perfect custom look. Aluminum CNC parts can be plated with various colors as per your requirements. Some of the colors you can try out include black, blue, and green.
The CNC machining of aluminum is subject to several changes especially in the design and specifications, which gives it the flexibility of a fast transition by starting off a newly examined and approved program. Getting back to the past program whenever you need is also achievable, with reliable manufacturing of ordinary quality in the arising aluminum removal items. Some of the typical aluminum alloys include aluminum 2024, aluminum 5052, aluminum 7075, aluminum 6063, and aluminum 6061.
Coming up with aluminum parts has been made effortless, thanks to the CNC machining process. The precision you get when extracting in such pieces is the main reason many consider this procedure useful. One can acquire convoluted models from the CNC machining process. Its simple nature and safety levels that you will enjoy with this method makes it the best compared to the others. You should try out CNC machining in the production of aluminum parts and enjoy the benefits and convenience.
