Engineering is one of the most important fields of study in the entire world which millions of students take up every year. Science is considered to be the basis of engineering as engineering brings into life concepts and innovations put forward by science. It is the study of all-natural phenomena so it becomes practically impossible to study everything in the same bracket. So, comes in the distinction of physics, chemistry, biology etc. In engineering, one of the main streams is mechanical engineering which deals with machines. This field concerns itself with the designing, manufacturing and use of machines.
One of the main aspects of mechanical engineering is production and manufacturing of machines. Machines are often made from many different parts which fit together to function smoothly as one unit. This means that for a machine to be made, a person concerned with manufacturing of the machines will have to manufacture the many components first and then assemble it. Once the material to be used for the components is decided, it needs to be shaped in such a way that it fits perfectly with the machine. The components can be manufactured in two main ways:
To build components in the right shape and size by forming. This type involves methods like casting, foundry, molding etc.
To machine blocks and billets to the required shape and size. This is very accurate as a large chunk or block of metal is taken and cut into the required shape.
The traditional method of machining components is by hand, done by trained experts operating machines like lathe, drilling machines, milling machines etc. This method is not preferred in most places nowadays as it is highly time consuming and requires a high level of skill by the operators. There is also scope for errors as it is done by human hand which cannot always be perfect. While high accuracy and precision is not required in some industries, most industries require components which are of high accuracy and precision. For example, in industries like the aircraft industry or the automotive industry, the dimensional tolerance is so low that any discrepancies in the dimension would get the component to be rejected only to be done again.
To get over this, people from such industries started to find CNC machining services to machine components to the perfect shape with high dimensional accuracy. Computer numerically controlled machines employ computer programs that execute numerical programs which has been input by operators. In this set up, the operators need to set the design and the dimensions while the CNC executes the program. This ensures that there are no dimensional inaccuracies during the machining process.
Apart from accuracy, another advantage of using CNC is that some components which are impossible to be machined by hand can easily be machined by a CNC. Some components are so complicated that they need to be machined along several axes. Traditional milling machines operated by hand can only be used conveniently and accurately along one axis but a CNC can be used to machine 6 axes. This is the reason to why industries strive to find CNC machining services which are reliable.
There are many different types of CNCs which can be purchased from many different companies. One of the main points of differences between the kinds of CNCs are the number of axes in which they can operate. CNC can also be used to carry out processes like prototyping, production etc. Good and reliable CNC machines and operators form the backbone of most manufacturing industries which is why they are in such high demand.
