CNC machining machines exhibit the capability to cut a diverse range of materials, including
aluminum, bronze, copper, ceramics, plywood, various steel alloys, stone, wood, zinc, and other
engineering materials.
This versatility makes CNC machining an ideal choice for generating prototypes in product
development. It enables precise and rapid adjustments until achieving the desired end product.
Product Details
Brass, an alloy composed of copper and zinc, is a highly sought-after material for various
components.
Its exceptional dimensional accuracy, sturdiness, durability, and resistance to corrosion make
it a widely demanded choice for copper-based products.
| Common Brass Materials | |
| No. | Properties |
| Brass C3600 | It has superior machinability, thread rolling and knurling characteristics. Typically used in the manufacture of fluid connectors, threaded inserts, couplings, and more. |
| Brass C3602 | It’s strength and resistance to corrosion with properties closely resembling that of steel. It is ideal for some of the most demanding conditions such as heavy industrial parts. |
| Brass C3604 | It is used in the mass production of brass components. It is widely used in manufacturing hardware, connector, flange and other machine parts by lathe and CNC. |
| Brass C4926 | A low leaded free cutting brass which conform RoHs and Reach environment regulations. Widely used on electronic parts, precision machine, valves, and related parts. |
Brass Finishing and Post-Processing
360 Brass has a shiny yellow finish that varies depending on surface roughness.
It can be hand-polished to increase its sheen, or media blasted for more of a matte texture.
| Name | Machining Marks |
| As machined | Visible, light surface scratches |
| Smooth machining | Visible, light surface scratches |
| Fine machining | Slightly visible |
| Polishing | Removed on primary surfaces |
| Bead blasting | Removed for non-cosmetic, removed on primary surfaces for cosmetic |
| Brushing | Reduced for non-cosmetic, removed on primary surfaces for cosmetic |
| Powder coating | Removed |
| Black oxide | Visible |
Applications of CNC Brass Parts
CNC machining is widely used in various industries, including aerospace, automotive, consumer
electronics, robotics, agriculture, medical devices, household goods, energy, and oil and gas.
It is a common and essential manufacturing process globally.

FAQ's
1. Can make design drawings for me?
Although we don't provide an independent product design service, we do conduct Design for
Manufacturing reviews for all approved orders. This involves partnering with our clients to
optimize their 2D and 3D drawings, ensuring better manufacturability, resolving design conflicts,
and minimizing production costs. Explore guidelines on how to prepare your CAD drawings for
manufacturing.
2. What are your tolerances for machined parts?
Our tolerances for machined parts are outlined below:
Local tolerances of +.005”/- .005” are applied across most geometries in metals, while plastics
have a tolerance variation of +/- 0.010". Tolerance specifications may vary for large parts,
especially concerning flatness after heat treatment.
For CNC parts with an "As Milled" finish, a minimum surface finish of 125 is required.
Fabricated parts adhere to a dimensional tolerance of 0.010” and an angular tolerance of 1°.
Tapped holes not explicitly identified as features on the quoted CAD model may be machined to
the diameters specified in that model.
Surface treatments (e.g., anodize, bead blast, iridite, powder coat, etc.) will not be applied
unless specifically paid for and acknowledged.
3. How Much Does CNC Machining Cost?
The cost of CNC machining a part is contingent on several factors, including:
1. Material: Different materials come with varying costs. Machining materials like Inconel are
pricier due to increased tool wear and slower cutting speeds compared to more economical
options like aluminum.
2. Complexity: Parts with intricate features incur higher machining costs. Complex surface
shapes, for example, contribute to increased expenses compared to simpler, flat surfaces.
3. Tolerances: Tight dimensional tolerance requirements contribute to elevated costs.
Needlessly specifying tight tolerances on non-critical features can increase CNC machining
expenses without added value.
4. Surface Finish: Achieving mirror finishes requires specialized tooling and strategies,
extending machining time and, subsequently, increasing costs.
5. Quantity: Low-volume production is inherently costlier per part due to the spreading of
initial setup and programming costs over a smaller quantity. Large-volume production offers
cost advantages as these setup costs are distributed over more parts.
