Advantages of Aerospace CNC Machining
At Tops Precision, we understand what aerospace components demand. Accuracy, reliability, and consistency come first. That’s why we use CNC machining to deliver exact results on every part.
Our process holds tight tolerances across full-scale runs. You always receive parts that meet critical specifications without variation. From engine mounts to structural brackets, each component is built to perform.
We work with advanced materials used across aerospace platforms. This includes titanium alloys, aluminium grades, and high-strength superalloys. Our machining protects material integrity and supports complex designs with ease.
Repeatability is another key advantage. Once a part is programmed, each unit follows the same precise path. That means no deviation in shape, size, or finish. So, you can count on us for medium to high-volume output.
Our CNC machining allows faster production without cutting corners. With fewer setups and real-time checks, we avoid delays and keep your project on track.
Every stage of the process is designed to meet strict aerospace standards. From early prototypes to final builds, Tops Precision ensures consistent quality with every part.

Aerospace CNC Machining Processes
At Tops Precision, we offer advanced CNC machining methods to meet your aerospace needs. We initially evaluate your diagram, choose the part’s shape, material, and how it will be used. Our goal is to provide precise, reliable parts every time.
3-Axis CNC Milling
The cutting tool is moved in 3 directions by 3-axis milling to create shapes on parts. It is effective with flat surfaces and single simple shapes, such as mounting plates and covers. Many simple aerospace parts can be produced with a high degree of precision in a short period.
We are oriented to maintaining close tolerances and finishes, particularly when using a material such as aluminium or titanium. That makes your components fit in the right places, right as intended.
4-Axis CNC Milling
With an additional fourth axis, this allows us to achieve intricate patterns. This implies that we are able to create the angled characteristics and rounded lines without having to remove the part. It is time-saving and precise.
This is perfect in cases of parts such as brackets or clamps that require precise machining on both sides. It also eliminates mistakes and accelerates the production process.
CNC Milling 5-Axis
We have 5-axis milling machines. These can move the tool in five directions simultaneously. This allows us to work with very complicated components with severe curvature or complicated shapes. This is applied in turbine blades, airfoils, and other extremely important components.
We save on accuracy through machining the parts all at once, eliminating errors that occur when several setups are used.
CNC Turning
It is ideal to use turning on circular parts such as shafts and bushings. We produce these parts on CNC turnings with close size control and smooth finishing. This is important for parts that revolve or come together.
We change the speed of cutting according to the material to prevent damage and maintain the parts' strength. Our turning machines are able to work both small- and large-scale production runs.
Wire EDM Machining
Wire EDM uses fine wire integrated with electric sparks to cut extremely precise shapes in hard materials. This is an economical process when it comes to working with parts having Sharp internal corners, tight-tolerance slots, intricate 2D profiles that cannot fit other machines. Inconel and hardened steel are tough materials we resort to Wire EDM. It does not heat or stress the metal at all and consequently produces clean edges.

High Precision Components and Tight Tolerances
At Tops Precision, we focus on producing aerospace parts with exacting precision. We regularly produce precision aerospace parts with close tolerances of +/-0.001 to 0.005 inches, with close attention to the requirements of the project.
To make everything in the right position, we also use GD&T callouts. We normally start at 0.020 inches, depending on the shape and material, with our smallest feature size.
In addition, we provide standard and customised threading services as well as tapped holes. Our machines can handle large-sized pieces that are 80 by 48 by 24 inches, and turned pieces are 62 inches long and 32 inches in diameter. So, we are in a position to accept very diverse aerospace parts, whether minor precision or major structure.
