Today you will know about CNC machining. This type of machining has been around for some time so it is important to know it. The great difference of this process to the rest is that it has the help of computers that control the machines and therefore do not require more than the minimum human intervention. This technology can be used in a wide range of operations for manufacturing, assembly, inspection, work on mechanical sheets and more. These types of machines are flexible, versatile and of high precision, helping us to save time and make fewer mistakes.
Advantages of CNC machining
CNC machining means Computer Numerical Control, is a form of programmable automation. The work carried out by these machines is controlled by coding, numbers, letters and symbols.
This type of machining was actually invented much earlier than you can imagine. In 1940, John T. Parsons already envisioned the use of punch cards as a position coordinate system to control a machine tool. Later, a large amount of research began to be carried out and finally the first prototype was made in 1952. There are different types of large cnc machining malaysia, the most common machines are milling machines, which automatically cut materials, even the hardest, use a tool for this cutting that can be moved in different positions and depths depending on the instructions sent to it through the computer.
On the other hand, there are grinding machines that use very robust abrasive discs to perform machining on materials such as metal or plastic. These machines are very simple to program and are used for projects that do not require as much precision.
There also are CNC routers that are used to make cuts in a wide variety of materials and it can be used in different cutters such as those that work with jets of water under pressure, lasers or plasma.
One of the great advantages of CNC machining is that they can be used 24 hours a day throughout the year and only have to be disconnected at the time of maintenance. On the other hand, they guarantee that the same design can be made, hundreds and thousands of times exactly the same. These machines can be programmed by advanced design software that allows us to make designs with them that you could not do with a conventional machine, in addition to allowing designers to simulate the manufacture of their idea without actually making a prototype, thus saving time and money. .
In any case, CNC machining, like all manufacturing processes, has advantages and disadvantages depending on the needs of the project, so it is necessary to weigh them all when choosing the most effective manufacturing process.
There are other types of manufacturing processes such as bar turning, 3D printing, molding or forging and it will be necessary to determine which process is suitable for each job. Sometimes the choice is easy: CNC would be the perfect option for the manufacture of a small number of solid metal parts with very precise incisions on the surface, while 3D printing would be the option for plastic parts with an internal pattern.
