Our CNC milling process is compatible with a great many raw materials. We use brass, stainless steel, hard plastics, titanium, and aluminum, among others.
With three-axis CNC milling prices starting at $10 per hour and 5-axis CNC milling center tolerances of up to 0.002″, our CNC milling services for prototype machining and production parts are remarkably cost-effective.
CNC Turning Services
We use high-quality, high-speed turning centers equipped with real-time tooling and automated bar feeders. Materials used in the turning process include aluminum, brass, rigid plastics, and mild or stainless steel.
Aria’s CNC turning services are designed to create elaborate external geometries with internal bores that result in exceptionally tight tolerances and radiant surface finishes.
This process is appropriate for rapid prototypes, introducing new products, and low-volume production.
Electrical Discharge Machining (EDM)
EDM machining is a process by which electric spark erosion is used as a cutting tool to remove metal under controlled conditions. The spark literally erodes the workpiece. We can then transform the eroded workpiece into the desired size and shape.
This tool can be used to cut holes and pockets into hardened steel. EDM is often used to fashion square pockets. It’s also used to impart a surface texture to the internal cavities of mold tools.
A high-powered electric spark is discharged by a sacrificial electrode residing in an electrolyte bath. The electric spark can erode extremely hard materials that would resist erosion with any other method.
Wire EDM is a variation of EDM. In this case, an electrically charged wire that’s fed continuously between two spools can cut through-hardened tool steel at high speed with impressive accuracy.

CNC machining is a subtractive manufacturing process. When the material is added instead of removed, it’s called an additive manufacturing process. Examples of subtractive CNC machining include specialized applications such as CNC milling services, turning, surface grinding, and EDM. An example of additive CNC machining is 3D printing.
Computer-aided design (CAD) files are digital records containing 3D designs and information about materials, processes, tolerances, and other variables. A digitally controlled CNC machine must always contain a file of the part design that controls it.
The spinning motion from the CNC machine’s cutter will leave visible tool marks. Although they stand ready for immediate service, they can be further refined with anodizing, painting, polishing, and plating.
