We specialize in multi-axis milling, turning, EDM, surface grinding, laser engraving and much more. In addition, you’re assured that all raw materials will meet your exact specifications because of our best-in-class testing and verification laboratory. That’s one of many reasons why we are a preferred supplier to world-class companies for their most demanding CNC machining projects.

CNC Machining – What Is It and Why Do You Need It?

CNC machining is a broad manufacturing category that includes many different computer-controlled processes where raw material is selectively removed in exact amounts to produce a near-final shape of parts. That’s why it’s considered subtractive, as opposed to additive manufacturing or 3D printing. Standard CNC machining processes include milling, turning, surface grinding and electrical discharge machining (EDM) although there are other specialized applications. Whenever a machine is digitally controlled there must always be a 3D CAD file of the part design which is used to program the machine’s movements.
CNC machining is used on many common metals such as aluminum, brass, mild and stainless steels, magnesium and titanium. It can also be used on rigid or engineering-grade plastic resins. We employ it every day to make not only finished parts but also tools and dies that are used for plastic injection molding and pressure die casting.
Because of the reliability and precision afforded by modern tools controlled with sophisticated software, CNC machining is an ideal rapid prototyping and production volume solution for making complex end-use parts with very tight tolerances.
One of the great advantages to CNC machining is its versatility. It is highly flexible and adaptable to many shapes and sizes of parts, and because there is no need for fixed tooling one part can be made just as easily as one thousand. CNC machined components are full strength and they have excellent surface finishes. You can choose to put them into service immediately or they can be further processed with additional treatments such as plating, polishing, anodizing, painting and more.

CNC Machining Raw Materials

We work with a wide range of plastic and metal alloy materials including magnesium, mild and stainless steel, aluminum, brass and titanium as well as rigid engineering grade plastic resins. These materials are part of our standard inventory and can be sourced for immediate availability from reliable vendors who have been thoroughly vetted and approved by us. In addition we can also provide specialty materials such as super hard alloys – just talk with our engineers to learn how we can meet your needs.
Most importantly, to ensure that your CNC machined parts meet all regulatory requirements we have an incoming materials inspection lab where we use sophisticated analytic testing instruments using Raman spectroscopy to confirm the exact chemical and physical properties of all raw materials. We leave nothing to chance for your peace of mind.
CNC Materials: How To Choose The Right Materials for CNC Machining


One of the great advantages to using CNC machining is its versatility. That’s because precision CNC milling and turning works successfully with a very wide variety of raw materials to produce finished parts. This gives design engineers many options when it comes to creating prototypes and commercial products. 
Most CNC turned and milled parts are made from metal. This is because metal is strong and rigid and can withstand the rapid material removal caused by modern tools.Let’s first take a look at the most common metals used for CNC machining.
 

Common Metal Materials for CNC Machining
In this section, you will learn the various common metal materials that are valuable for CNC machining. We’ve listed these materials below.

Aluminum 6061

This is the most common general purpose aluminum used for CNC machining. The main alloying elements are magnesium, silicon, and iron. Like all aluminum alloys it has a good strength-to-weight ratio and is naturally resistant to atmospheric corrosion. Other advantages of this material are that it has good workability and CNC machinability, can be welded and anodized, and its wide availability means that it’s economical.
When heat-treated to a T6 temper, 6061 has a considerably higher yield strength than annealed 6061, although the price is slightly higher. One of the drawbacks to 6061 is poor corrosion resistance when exposed to salt water or other chemicals. It’s also not as strong as other aluminum alloys for more demanding applications.
6061 is a material that’s typically used for auto parts, bicycle frames, sporting goods, some aircraft components, and frames for RC vehicles.
