CNC machining is a versatile and cost-effective manufacturing process. The process is suitable for a wide range of materials. As a result, CNC machining can help a wide range of industries make parts. Manufacturers and machinists use this process in a variety of ways. This includes direct manufacturing processes, indirect manufacturing processes, or processes that are combined with other processes.

As with any other manufacturing process, the unique benefits of CNC machining dictate the types of applications it can be used for. However, the benefits of CNC have room for almost any industry. They are applicable to many parts and products. Because CNC machines can process virtually any type of material, they are used in a wide variety of applications.

From part production to rapid prototyping, this article looks at a variety of common applications for CNC machining. Let’s get started!

Industries that use CNC machining
CNC machining for prototyping is not dependent on any single sector. People use it almost everywhere. It helps create everything from aircraft parts to surgical tools. Therefore, we can find applications for CNC machining in different industries. The following industries benefit from CNC machining purposes:

Aerospace industry
The aerospace industry has a long history with CNC machining. Metal aircraft components are machined with the highest precision and complexity. This is important for safety-critical applications. In addition, the CNC-compatible range of engineered metals offers a wide range of options for aerospace engineers.

CNC machining is widely used and reliable in the aerospace industry. Some of the aerospace components that can be machined include engine mounts, fuel flow components, landing gear components, and fuel access panels.

Automotive Industry
The automotive industry often uses CNC milling machines for prototyping and production. Extruded metals are machined into cylinder blocks, transmissions, valves, shafts and a variety of other components. On the other hand, CNC machines plastics into components such as instrument panels and fuel gauges.

CNC machining in the automotive industry is also useful for creating one-off custom parts. A variety of replacement parts can also be created using CNC. This is due to the fast turnaround time and the fact that there is no minimum required number of parts.

Consumer Electronics
CNC machining is also useful for prototyping and production of consumer electronics. These electronics include laptops, smartphones, and more. For example, the chassis of the Apple MacBook comes from CNC machining of extruded aluminum, which is then anodized.

In the electronics industry, CNC machining helps manufacture PCBs, housings, fixtures, fixtures and other components.

Defense Industry
The military sector often turns to CNC machining to create robust and reliable part prototypes. The goal of machining is to make parts that can withstand wear and tear with minimal maintenance.

Many of these parts overlap with other industries such as aerospace and electronics. The ability of CNC machines to provide on-demand replacement parts and upgrade components is particularly useful in this industry. As such, it is suitable for parts that require constant innovation and safety.

Healthcare Industry
CNC machining can be used for a variety of medical safety materials. Because the process is suitable for one-off custom parts, it has many applications in the healthcare industry. The tight tolerances offered by CNC machining are critical to the high performance of machined medical components.

CNC can machine medical components including surgical instruments, electronic housings, orthopedic devices and implants.

Oil and Gas Industry
Another industry that requires tight tolerances for safety-critical applications of CNC lathes is the oil and gas industry. This industry uses CNC milling machines to machine precision, and reliable parts such as pistons, cylinders, connecting rods, pins and valves.

These parts are often used in pipelines or refineries. They may require smaller quantities to fit specific volumes. The oil and gas industry often requires corrosion-resistant machinable metals such as aluminum 5052.

Manufacturing possibilities with CNC machining
Another way we can classify CNC machining applications for CNC is the manufacturing possibilities and uses. CNC machining is useful in the following areas:

Rapid prototyping
CNC machines have a fast turnaround because they are highly autonomous. Once the digital designs are completed, the machinist can send them to the CNC machine and have them manufactured in a short time. This makes CNC machining very useful for prototyping. The use of CNC lathes is robust regardless of the method used to machine the final part.

Production
CNC machining is precise enough to produce high quality parts for CNC end use applications. The material versatility of the process allows for a wide variety of parts to be manufactured. Overall, CNC machining is a cost effective manufacturing process for many projects. Regardless of size or scope, a number of industries use the manufacturing process to create usable end-use parts.

Tooling
In addition to being an excellent direct manufacturing process, CNC machining is an indirect manufacturing process that aids in processes such as injection molding. It helps machine a variety of steels and strong aluminum. Machined parts such as metal molds can be filled with other materials to create a large number of products.

Hybrid Manufacturing
CNC machining does not have to be used independently of other manufacturing processes. Combining it with other processes such as 3D printing or metal casting can produce quality parts and products.

Hybrid manufacturing applications for cnc machining
For example, features such as holes and threads can be machined in printed parts or castings using CNC machines.

Electric discharge machining (EDM)
CNC automation enables electric discharge machining (EDM) in two ways. It allows vertical EDM, which requires electrodes with a similar shape and size to the cavity to be carved out. Another type of EDM is Wire EDM. This type helps to create punch and die combinations for the different die sets used in metal and plastic manufacturing.
