Need Rapid Prototypes Or CNC Machined Parts?
CNC machining is liked by engineers all over the world because it’s one of the most accurate manufacturing technologies out there. And it is very price-competitive for one-off custom parts and low volume production
Available Material For CNC Machining
Similar types of material can be used for a variety of products and result in varying capabilities. It’s important to start with considering the end results of how your part will be used.
Aluminum is a highly ductile metal, making it easy to machine. The material has a good strength-to-weight ratio and is available in many types for a range of applications.
- Aluminum 6061
- Aluminum 5052
- Aluminum 2024
- Aluminum 6063
- Aluminum 7050
- Aluminum 7075

CNC Machined Parts Tolerance
Tolerances are greatly affected by part geometry and type of material, the tolerance will be followed by the 2D drawings. Without 2D drawings, we will follow the ISO2678 tolerance standard. If you require a tighter tolerance, please contact us.
| Metals With Drawings | Plastics With Drawings | No Drawings | |
|---|---|---|---|
| Linear Dimension | +/-0.02mm +/-0.0006 inch | +/-0.05mm +/-0.002inch | ISO2768 |
| Hole Diameters | +/-0.02mm +/-0.0006 inch | +/-0.05mm +/-0.002inch | ISO2768 |
| Shafter Diameters | +/-0.01mm +/-0.0003 inch | +/-0.05mm +/-0.002inch | ISO2768 |
CNC Machining Finishes
Due to the reduction of the machining process, the surface of the part will have smaller tool marks after machining. However, we can use a variety of methods to improve the surface roughness, visual properties and wear resistance of CNC machined parts
Powder Coating
This is a process where powdered paint is sprayed onto a part which is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. A wide variety of colors are available to create the desired aesthetic.
Anodize
Under the corresponding electrolyte and specific process conditions, aluminum and its alloys form an oxide film on the aluminum product (anode) due to the action of the applied current.
Painting
The purpose of the painting is to make the monotonous products look more beautiful after spraying various colors, and at the same time, because of the extra layer of protection, the using time of the products can be extended.
Electroless plating
Electroless plating can also be called autocatalytic plating. The specific process refers to: under certain conditions, the metal ions in the aqueous solution are reduced by the reducing agent and precipitated on the surface of the solid substrate.
Black Oxide
Blackening is a common method of chemical surface treatment. The principle is to produce an oxide film on the metal surface to isolate the air and achieve the purpose of rust prevention. When the appearance requirements are not high, blackening can be used, and the surface of steel parts is blackened, which is also called blue.
Passivation
Passivation is the process of treating or coating a metal to reduce the chemical reactivity of its surface. In stainless steel, passivation refers to the use of an acid solution to remove free iron from the metal surface to prevent rust
