About CNC Machining

CNC machining allows anyone with the right knowledge and skills to manufacture virtually any object, through the use of computers and advanced programs that control highly precise machining tools. They see heavy use in the manufacturing sector, thanks to their accuracy, speed and efficiency compared to human effort.

Benefits of CNC machining

• Fast – After an object has been designed, it can be created by the machine without the delays caused by slower human movement.
• Durable – CNC machines are built to last; only requiring maintenance every now and then.
• Precise – No matter how small or large the object, CNC machines can fabricate it with minimal errors or mistakes. Thanks to their precision, some objects are only possible because of CNC machines.
• Versatile – Several tools can be connected to CNCs, allowing the machine to control them. They can also perform a variety of machining techniques.

How CNC machining works

The main component in CNC machining is the CNC or Computer Numerical Control, which is composed of a computer and a specialised CNC program. Together, they’re the brains behind the whole outfit but it still requires a skilled CNC machinist, someone who is familiar with the software and the machine tools attached to the CNC.

To illustrate the difficulty of CNC machining, the machinist has to use the software to create precise designs of their project and adjust settings for the tools such as speed, feed rate and location. Afterwards, they have to create a prototype to check for errors or defects. In exchange for the added complexity, CNC machines can produce components rapidly and accurately, without any human input if the prototype has passed quality control.

What kind of machining tools can be attached to the CNC?

Many machining tools have been adapted to be compatible with CNC software; here are some examples of these tools:

• Routers
• Grinders
• Mills
• Drill press
