CARVING FOAM MACHINING CNC MACHINE MILLING CNC TURNING SERVICE ECCOSTOCK MACHINING EMI/RFI SHIELD MACHINING PHENOLIC MACHINING PLASTIC MACHINING RIGID FOAM MACHINING What Is CNC Machining? CNC machining is a manufacturing process that uses programmed computer software, instead of manual control, to guide the machinery, ultimately creating the part you need. Much like 3D printing, it turns the virtual part design in the computer software program into the physical part. However, the way it works is very different from 3D printing. For example, you may begin with a large block of carving foam, but once it is manufactured through CNC machine processes, it could become a piece of insulation or packaging for electronics. Custom CNC machining is used in a variety of industries — especially industries where pieces are mass-produced and need to meet specific requirements, such as a preferred level of tolerance. For example, you’ll find that a certain type of CNC machining is used to create insulation pieces, automotive parts, and even the tiniest and most delicate pieces in small electronics. In the aerospace and military industries, where demands are high, CNC machining is used to develop parts that meet those demands with accuracy and precision. CNC Machining Material Types There is a wide variety of materials that may be used in CNC machining. The type of material depends upon the part you’re creating. Whether you’re ordering material to run on your own computer numerical controlled machine or looking for custom CNC machining services, choosing the right high-quality material is essential. At AMI, we offer rigid foam, carving foam, phenolics and plastics. What you select depends on the application. We’ve included some information on the characteristics of each of these materials, as well as the applications they serve, below. Rigid Foam Rigid foams are used where the product design or application requires structural integrity, temperature compensation and thermal and mechanical stability. Rigid foam is used in satellites, radomes, antennas and packaging for electronic enclosures. Rigid foam is also used as an architectural and structural replacement for conventional wood and aluminum applications. We offer rigid foam CNC machining using: Rigid Foam Insulation Structural/Core Foam Microwave Foam High-Density Foam Phenolic Foam Polyethylene Polyimide Foam Polyurethane Foam Rigid Urethane Foam Polystyrene Learn more about the differences and advantages of using each of the custom rigid foam CNC machining materials. Carving Foam Carving foam is one of the best materials for carving or sculpting because it’s lightweight, soft and dense. It also has good resistance to moisture and temperatures, as well as general wear and tear. As a result, carving foam is often used for various types of insulation and prototypes for molds, as well as to manufacture gaskets, seals and other components. It’s also popular for soundproofing applications since it contains polyisocyanurate — a thermoset plastic material that absorbs sound. We offer four different types of carving foam. While our #2 and #3 products can be hand-carved, our #4 and #6 foams require CNC machining. This makes them suitable for the mass production of custom electrical components. Foam can be cut, glued or coated with other materials to bring your particular part to life. You can order blocks of our carving foam and cut them yourself, or you can send in a drawing and let us do the custom foam CNC machining for you. Phenolics We can machine components from various phenolic materials, many of which meet MIL-I-24768 and related requirements. Our CE and LE product lines offer exceptional mechanical properties, whereas our glass phenolic material — also known as Garolite® — can be used to insulate a range of custom electrical components. CE and LE phenolic: CE phenolic is produced from a medium weave cotton cloth impregnated with a phenolic resin binder. LE phenolic is constructed from a fine weave linen cloth impregnated with a phenolic resin binder. This type provides a better finish for machined components, especially those with intricately detailed elements. Glass phenolic: Our glass series is a glass-woven fabric impregnated with various resin binders to optimize the material’s unique characteristics, making it ideal for electrical insulation. All phenolic products are available in multiple colors and sold in sheet stock, rod, angle and U-channel forms. Plastics There are many types of plastic materials used in manufacturing. We work with the most popular types to meet customer demands in the aerospace, automotive, medical and electronic industries. Our plastic CNC machining can be done using: Acetal (POM) Acrylics (PMMA) Noryl® (PPO) PVC PVDF PC PP Teflon® (PTFE) UHMW (UHMWPE) Typical applications include bearings, bushings, tubes and electrical insulation, among others. Whether your finished component must possess high impact strength, superior temperature resistance, a low coefficient of friction or any other specific property, we have the expertise to help you select the best plastic material and machining technique for your project requirements.

Types of CNC Machining Not all parts are created equal. Just as there are a variety of different parts, there are also a few different CNC machining techniques used to create them. CNC machine turning, CNC machine milling and CNC screw machining are the three main types. They can be used individually or together to create the unique part you need. We’ve included some specific information about each of them and their applications below. CNC Machine Turning CNC machine turning is one of the most common computer-controlled machining processes. It can help you create cylindrical parts of various sizes and dimensions. Here’s how it works: After placing the workpiece horizontally on a mandrel, the CNC machine rotates it. The lathe or other cutting tool strips away the excess material to form the outer area of the workpiece into the desired shape. In addition to creating the cylindrical part, many of these machines are also equipped with a horizontal drill to drill a hole through the center. CNC machine turning can be used on its own or in combination with other manufacturing processes. On its own, however, this method can’t be used to make oddly shaped parts. Despite offering an exact — but limited — function, it’s a perfect fit for the right job and provides low setup and tooling costs. CNC machine turning is an excellent solution for mass manufacturing. The process is automated, which keeps labor and setup times to a minimum — a benefit for manufacturers looking for an economical way to bring their product to market. CNC Machine Milling CNC machine milling works like this: You place the workpiece in a machine vice. The table automatically moves around the tool, based on the software programming you’ve input. Multiple tools can be installed on a single mill, allowing you to create complex parts. There is a wide range of cutting tools available for CNC machine milling so that you can create different shapes of various sizes. For example, conventional drills and bores may be used to create simple holes. Endmills, chamfer, grooving, rounded and other tools are used for more complex work to create bevels, rounded edges and other features. One thing to consider is that because the workpiece must be held firmly in place, it’s not a good fit for flimsy or oddly shaped materials. Because the milling process is automated, once you program the software to perform the actions to create the workpiece you want, most of your work is done. Programming the software means you’re able to repeat the process over and over again with exceptional accuracy. Consequently, it’s no surprise milling is best for mass-produced parts and short-runs. Workpieces made from metal, wood, plastic, rigid foam and other materials are an ideal fit. CNC machine milling is often used to create automotive components, construction materials and other items — and its accuracy makes it ideal for meeting quality control requirements for automotive, aerospace and military applications. CNC Screw Machining CNC screw machining is recognized for producing items with extremely high dimensional tolerances (+/-.005”). Here’s how it works: A disc cam feeds the workpiece through a guide bushing to get it as close to the tool as possible. You move the part instead of the tool, leading to less vibration and deflection. Because of this decreased movement, you achieve closer tolerances during production. These machines are also known as Swiss-style lathes. As the name suggests, these devices produce the intricate parts that go into the country’s famous watches. As technology has continued to advance, this type of CNC machining has become particularly useful for technology — specifically in cars and trucks, medical devices, electronics and other manufacturing parts. Pins, pivot rods, spaces and electronic connectors and terminals are all ideal for CNC screw machining. What could be the downfall of a machine that is capable of creating such intricate parts? It comes at a cost. The guide bushing has to be precisely positioned to maximize performance — and that means you need extra setup time and a skilled person on staff who knows how to work the machinery properly. These are two factors that will lead to higher manufacturing costs.

Our production CNC machining process lets us work one-on-one with you or your engineering and design department to quickly create one or more parts — regardless of its size or complexity of the design — so you can inspect the item and compare it to your established standards or guidelines. Prototyping is also an efficient method for evaluating a product’s usability, including how the weight and size fit into a user’s hand or a machine’s internal components department. CNC prototype production capabilities can alert you to potential problems or considerations that you can’t evaluate through computer programs alone. A CNC prototype is the best way to ensure you’ve chosen the right material, process, dimensions and specifications for your product before creating a larger quantity.
