The process of our custom CNC machining service involves leveraging the predominant
subtractive manufacturing technology of CNC machining.
This method is particularly effective in crafting bespoke metal and plastic parts for both prototyping
and production needs.
Through the utilization of CAD modeling software and G-code, CNC milling and CNC turning
machines meticulously remove material from solid workpieces with precision and efficiency.
Our service excels in delivering sturdy components with stringent tolerances and diverse material
properties, both mechanical and chemical. Its applicability extends seamlessly to one-off projects
and low-to-medium volume production, facilitated by automation and high repeatability.
Product Details
CNC machines are employed across a diverse range of materials, each having its optimal set of
machining parameters (speeds and feeds) for successful processing.
The most prevalent materials include:
1. Metal:
Metal stands out as the most frequently utilized material in CNC machining. CNC machines have
the capability to cut nearly any type of metal, from free-machining brass to high-performance
nickel superalloys like Inconel. Metal machining caters to various applications, ranging from injection
molds to the production of shafts and gears.
2. Plastic:
Although the majority of plastic parts are manufactured through injection molding, CNC machining
finds application in producing specific plastic components. Common materials include ABS
(acrylonitrile butadiene styrene), nylon, and polycarbonate.
Plastic machining applications encompass valve bodies, bushings, and the creation of injection
molding prototypes to assess the overall functionality before investing in costly molding tools.
3. Wood:
CNC routers are predominantly used for wood cutting and are generally more cost-effective than
standard metal-cutting CNC machines. Wood CNC machining is commonly employed for decorative
purposes, with applications such as furniture, window frames, and ornamental panels.
4. Foam:
Polyurethane foam, whether closed or open-cell, is frequently employed in CNC machining applications.
CNC routers can cut foam blocks to create secure packaging for high-value products.
An example is the use of foam in toolboxes to ensure the tools remain secure during transportation.
5. Composites:
CNC machines are regularly employed in processing composite parts. Composites may include
materials like aramid, fiberglass, or carbon fiber, which are highly abrasive to cutting tools.
Aerospace and marine composite components undergo machining for tasks such as adding fastener
holes and general trimming after the molding process.

Post-processing and surface finishes for CNC machining
CNC-machined parts as they emerge from the machine often exhibit visible tool marks,
a feature that may not align with your specific part requirements.
Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the
surface appearance and elevating attributes such as wear resistance, corrosion resistance,
and chemical resistance.
Methods like anodizing, bead blasting, and powder coating present viable options for refining
the final presentation of your custom parts, allowing you to achieve the desired surface
quality and performance characteristics.
