Computer Numerical Control (CNC) is a variety of digital applications that are used to control machine tools used in the industrial production of parts. In fact, CNC machines are used to fabricate numerous parts, from small sizes up to larger scales, and are used across a variety of industries.
Machinists are often those skilled tradesmen who are trained on CNC applications and are responsible for setting the values used in the creation of machined parts. If you’re looking for a CNC machine for sale, then it would help if you’re well-versed in the nomenclature and attributes of such complex applications.
This article will explore the uses of CNC machines and the industries in which they are most commonly found and used.
Why is CNC Machining is Preferred?
Though it’s considered a true craft to build parts by hand, today’s industries have become so complex that they demand intricate precision. This precision can often be the defining line between life or death situations.
For example, those who work in the aerospace or medical industries require machines that require specific parts in order to operate and function appropriately. When making that part with a CNC machine, a minute flaw can be fatal when a machine that operates using high-energy rotation fails, stops, or falls apart. Misaligned parts in an aircraft can cause an engine to fail, and machine-driven surgical tools and other apparatuses need this precision to function without failure.
CNC precision is preferred because component failure could cause product failure and ultimately place lives at risk.
What are CNC Machines Used For?
When looking for a CNC machine for sale, you probably have a specific use in mind, which is why you want this machine. Computer Numerical Control actually operates a variety of machines and are used across a variety of industries, including the following:
- Medical Industry
CNC machines are used in the medical industry largely due to the precision components needed to operate machines or to fabricate specific parts down to the finest detail. The following are a few products made by CNC machines:
- MRI Machines
- Electrical Components
- Orthotic Devices
- Shielded Enclosures
- Medical Instruments
Though there are numerous other uses, the medical industry is one that requires the utmost precision in components due to the lives at risk in most procedures.
- Aerospace Industry
The aerospace industry works with high speeds, air currents, and extreme pressures to name a few elements that require high precision components that won’t fail when a vessel is in flight. The following are a few components that require the use of CNC machines:
- Landing Gear
- Instrument panels
- Radiofrequency Suppression Equipment
With all of the complex mathematics involved in aerospace science, the precision systems included in aircraft and spacecraft must include CNC machined parts in order to operate at a functional level.
Using CNC Machines
Most CNC technology is used and operated by CNC Machinists. This profession is one that typically begins as an apprenticeship where an individual works under experienced machinists and learns the trade over time.
Some machinists may choose to attend a trade school or receive an associate’s degree in CNC machining prior to beginning their careers. However, most work their way up over a period of time which typically lasts between two and four years.
If you or your business requires the use of CNC machining, it’s highly recommended that you receive some training on the apparatuses involved before machining any parts for industrial use.
