CNC CAPABILITIES

CNC Milling

If your part is any sort of shape other than cylindrical, or lacks rotational symmetry about some imaginary axis through the part body, then a CNC mill is likely the machine for you. With milling, the stock that the part will be cut from is usually a six-sided bar or sheet of material (though it can also be a cylindrical rod).

We offer both 3 and 5-axis machining capabilities. To optimize for speed of production, we recommend minimizing the number of setups to leverage 3-axis machining.

CNC Turning

We offer both standard and live-tooling CNC turning. As with CNC milling, we recommend limiting the need of live-tooling to speed up the prototyping process.

The Fictiv network connects hundreds of highly vetted machinists across the country. This gives engineers streamlined access to a wide range of 50+ models of CNC Lathe machines, including: Haas ST-30SSY (live tooling), Akira Seiki SL-30, Doosan LYNX 300

CNC MATERIALS

Nylon
Relatively high chemical and heat resistance. Stiff enough to retain its shape, but tough enough not to permanently deform under load. Use cases: medical devices and electronics insulation, notably screws and spacers for panel mounted circuit boards.

Nylon has a milky-white finish and is slightly translucent.
ABS
Low-cost engineering plastic, widely used for pre-injection molding prototypes. CNC machined ABS is a great option for production-like parts, where detail and mechanical properties are important.

ABS has a somewhat matte finish (think LEGO bricks) and can be painted. Certain faces may appear more shiny, depending on their geometry and how they’re machined. If painting ABS parts, finish will depend on the choice of paint.
Acrylic
Scratch-resistant plastic, available optically clear or opaque. Often used for tanks, panels, and optical applications.  It can be somewhat brittle in thin-walled areas, so it is not recommended for delicate or complex geometries.

Also known as PMMA, an abbreviation of its full chemical name, polymethyl methacrylate, and by the trade names Plexiglas and Lucite.

Acrylic is transparent or opaque (black, white, and a variety of colors) in its unfinished state. Clear acrylic will take on more of a frosted translucent appearance when machined; though it can be smoothed again to an optically clear state using various finishing methods.
Delrin
Delrin (generic: acetal) is a low-friction, high-stiffness material that's wear and moisture resistant. It is used in applications ranging from auto parts to musical instruments. With a relatively high toughness and minimal elongation, Delrin boasts excellent dimensional accuracy.

Delrin is naturally opaque white because of its crystalline structure and has a matte finish.
HDPE
High-density polyethylene (HDPE) is a slippery plastic that is often machined into plugs and seals. It is also an excellent electrical insulator as well as being moisture and chemically-resistant.

HDPE is a naturally opaque white because of its crystalline structure, but it is also available dyed black in more limited stock sizes. It has a waxy finish leveraged for low-friction applications.
Polycarbonate
Polycarbonate (also known by the abbreviation PC) is one of the most common plastics used in manufacturing. Famous examples of the material are first-generation MacBook laptops, safety goggles, and optical disks.

Polycarbonate is heat-resistant, impact-resistant, flame-retardant, and one of the most recycled plastics in the world.

Polycarbonate has a transparent milky-blue look in its natural state but is also available in black. Both colors have a glossy finish and are relatively prone to scratches. Anti-scratch coatings and vapor polishing are available as custom post-processing finishes.
1018 Steel
1018 Low Carbon Steel is a mild, low carbon steel that is machinable, weldable, and useful where high-strength is not required, such as fixtures and mounting plates. It is magnetic and heat treatable.

The finish of 1018 Steel is similar to that of Stainless Steel, generally shiny in appearance and slightly darker than aluminum alloys. Carbon steel can be media-blasted or hand-polished to a variety of surface finishes.

Aluminum
Aluminum is one of the most commonly used metals in the world because of its excellent strength-to-weight ratio, low cost, and recyclability. Fictiv offers multiple aluminum alloys.

Our standard alloy on platform is 6061, a versatile and easy-to-machine metal. It is corrosion-resistant, non-magnetic, and heat treatable. 7075 Aluminum is a hard, high strength alternative to 6061 Aluminum . It is often used for parts in high-stress applications, and is also corrosion-resistant, non-magnetic and heat treatable. Also known as jig plate or cast tool, MIC6 is a cast aluminum alloy that is great for tight tolerance applications due to it being stress-relieved. It is most commonly used in precision machine tables and tooling. MIC6 is non-magnetic and not heat treatable.

Untreated aluminum generally has a dull silver/grey finish that varies depending on the roughness of the surface. Many consumer products made with aluminum are anodized, which allows for a variety of color options and adds a consistent shine across the entire part. Aluminum can also be media-blasted, sanded, and hand-polished to achieve a multitude of surface finishes. Alodine is often used as an alternative protective coating to anodize on aluminum parts, and can be clear or gold in color.

360 Brass
360 Brass is also known as free machining brass, due to it having the highest amount of lead content of any brass alloy. This excellent machinability comes with minimal tool wear. It is commonly used for a variety of parts such as gears, lock components, pipe fittings, and ornamental applications.

360 Brass has a shiny yellow finish that varies depending on surface roughness. It can be hand-polished to increase its sheen (think trumpet or saxophone) or media blasted, for more of a matte texture.
Stainless Steel
Stainless steel is highly resistant to corrosion and rust, making it suitable for situations where a part may be exposed to the elements for long period of time. Stainless steel is also fairly malleable and ductile. Fictiv offers multiple stainless steel alloys, including a food-safe variety.

The 300 series family (303, 304, etc.) are austenitic stainless steels (after their crystalline structure) and are the most widely produced grades worldwide. Austenitic stainless grades are known for their high corrosion resistance and high strength across wide temperature ranges. They are not heat-treatable, except by cold working, and are generally non-magnetic.

400 series stainless steels are the martensitic family and not as common as austenitic grades. Martensitic steels are extremely strong and tough due to higher carbon content, but more susceptible to corrosion in certain environments.  They can be heat-treated to greatly increase their hardness and are magnetic.

17-4 PH Stainless Steel is a high-strength, highly corrosion-resistant material that maintains its durability up to 1100°F. The PH in its name stands for precipitation-hardened, a type of treatment it undergoes to increase yield strength. It is magnetic and heat treatable to a hardness of approximately Rockwell C50.

The finish of stainless steel varies, depending on surface roughness, but it’s generally characterized as being more shiny than unfinished aluminum alloys and slightly darker and more silver in color. Stainless steel can also be media-blasted, sanded, hand-polished, and powder coated to achieve a multitude of surface finishes.
