Before we discuss CNC machines, we need to know what exactly are machines and why they are needed. cnc machining came into existence. Everyday we are constantly surrounded by machines. You might see an embroidery machine, a drilling machine, or a complex car engine.


All machines have the same function: to ease the burden of life and reduce the amount of effort required by humans. A majority of the machines that surround us depend on the human mind for important decisions. In the case of a conventional drilling machine, we must stop it when drilling is completed. The machine can’t tell by itself that whether the hole has been drilled or not. This is similar to other machines.


There is a major issue with theses machines and that is caused by manual operation. We are all aware that there are many problems with human beings. For example we get fatigued, emotional, and are prone to making mistakes.


All of these factors forced engineers to develop machines that can carry out certain tasks with no human involvement. It is also desired that these machines should have the highest accuracy and prevent any accidents. CNC machines can help.


What is a CNC machine?

The word CNC refers to computer numerical control. This is where the tool and workpiece are controlled by a numerical program.


The entire process of cnc machining relies on CAD/CAM. Computer Aided Design stands for Computer Aided Design, while Computer Aided Manufacturing stands for Computer Aided Manufacturing.


CAD allows us to design an 3D representation of the item we’re creating. CAM converts that design into reality. Modern day CNC machines are extremely precise and reduce the time to perform a job drastically.


The advantages of CNC machines

Machining is accurate

It is very quick to finish a job.

Operate safely

The number of operators needed to operate machines are reduced

There is no chance of human error

Reliable

Even complex designs can be designed.

Maintenance is minimal

They can be used in a myriad of ways

Uniformity in design

They could run for all day, every day


Advantages of CNC machines

They are costly

An operator who is properly trained is required to operate the machine.

If a problem arises, the assistance of a skilled professional is needed to resolve the problem


The applications of CNC machines

Due to the high precision that machine shop can provide, CNC mills are used in a wide variety of industries, such as the medical, aerospace, and electronics industries.


They are used in aerospace industries for the production of manifolds and bushings and landing gear components.


CNC milling machines are employed extensively in the medical industry for the production of prostheses, medical devices and other FDA-approved medical devices. In addition, CNC mills can be utilized to make heat amp housings, heat sinks, and other electronics parts used in the electronics industry.


What’s more, CNC milling machines play vital roles in the operation of various modern manufacturing technologies. For instance, the precision copper mold patterns and cavities utilized during the process of injection molding are usually created using CNC mills.
