CNC Machining Turning Aluminum CNC Precision Metal Parts Custom Aluminum
CNC Service Milling Stainless Steel Parts
CNC machining stands as the prevailing subtractive manufacturing method today,
offering remarkable versatility and reliability in crafting bespoke metal and plastic components.
Leveraging CAD models, CNC machines meticulously eliminate material from solid blocks using
a diverse range of cutting tools.
In essence, CNC machining yields parts with precise tolerances and exceptional material
characteristics.
It finds applicability in individual projects and low-to-medium volume production
(up to 10000 parts), owing to its superior repeatability.
Nonetheless, it imposes more design constraints compared to 3D printing, largely due to its
subtractive nature.
Product Details
CNC machines are capable of cutting a wide range of materials, including aluminum, bronze,
copper, ceramics, plywood, various steel alloys, stone, wood, zinc, and various engineering
materials.
This versatility makes them an excellent choice for crafting prototypes during product
development.
Furthermore, CNC milling allows for precise and rapid adjustments until the desired final
product is achieved.

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.
