What Industries Use CNC Machining: How Demmer Manufacturing’s Affiliates Operate

Many industries use CNC (computer numerical control) machining to fabricate custom parts from metal, plastic, and other materials. CNC machining enables manufacturers to create precise, intricate parts using computer software for different businesses that require perfect production at a high volume. Let’s take a closer look at CNC machining and the industries that rely on it.

How Does CNC Machining Work?

CNC machining can handle small or large component creation while maintaining quality consistency. This is essential for producing the same part precisely and repeatedly. An engineer uses a computer program to guide the CNC machine to mill, grind, cut, drill, bore, or lathe the material into the desired shape for the production run. Possible materials include metal, plastics, and foam. There are several devices used depending on the requirements and material:

• Machine milling for highly detailed parts, a process that turns numerous tools around the piece to shape it into the desired form.
• Machine turning, which allows for mass production of custom parts. It functions like a lathe. The CNC control cuts parts applied to the turning workpiece.
• Screw machining, which produces precise parts that can be incredibly small.

The control that engineers have over the part via these devices and computer programming means that little to no manual intervention is needed during production. CNC machines are invaluable in industries where there is no room for human error—and they cut down on labor costs and waste.

Industries That Use CNC Machining

CNC machining allows Demmer’s affiliates to create parts for various industries that rely on fast production and precise, consistent components. CNC machining is fully automated to fabricate accurate parts that meet the stringent requirements in the following sectors:

Aerospace

Vessels in the aerospace sector experience extreme pressure, temperature, and high speeds. Any inaccurate part or component can increase wear or create drag, leading to dangerous conditions. Tolerances for aerospace manufacturing may be as tight as 0.00004 inches to ensure parts meet exact specifications. Products may include:

• Bushings
• Parts for landing gear
• Manifolds
• Electrical connectors
• Antennae
• Radiofrequency suppressors
• Airfoils

Medical

The medical industry relies on products that are used on patients, sometimes in life-or-death situations or sterile settings. These products may include:

• Medical instruments
• Sterile packaging
• FDA-approved products
• Implants
• Monitoring devices
• MRI machines
• Orthotic devices
• Research equipment

Parts for these products have no room for error, as they must fit together to function as intended and be safe for use in hospitals and medical offices.

Defense

The military requires precision, secrecy, and the ability to easily upgrade their parts to meet new specifications. CNC machining meets these requirements for:

• Transportation parts
• Plane components
• Communications modules
• Various electronics

Transportation

The transportation sector not only needs precision to ensure the safety of the individuals operating a car, truck, or boat, but it also requires testing for the strength and durability of the parts themselves. This may include parts for:

• Passenger vehicles
• Passenger rail cars
• Transport trucks
• Shipping vessels
• Freight trains

These industries also need parts prototyping and testing for longevity and accuracy, for which CNC machining is vital. CNC machines are designed to produce components that match each production run’s specifications; however, there are factors that can negatively affect the quality of the part. To address this and ensure exact precision, Demmer’s affiliates make sure that each part is consistent by employing quality control systems and using the most advanced CNC technology to guarantee accuracy. Our precision means our affiliates generate high-volume production and fabrication of accurate parts, as well as lowered costs and reduced overhead.

Invaluable Production Accuracy

With CNC machining, we can increase efficiency and scale to almost any volume. As our portfolio companies grow, so can their production volume, even for the most complex and intricate parts. Some manufacturers have even begun using predictive technology to catch errors before they occur to ensure machines don’t break down, thereby reducing production downtime.
