CNC machining employs subtractive processes, wherein the feedstock undergoes machining to
attain its final shape by systematically eliminating material. This involves tasks like drilling holes,
boring pathways, and shaping metal stock into new material with diverse tapers, diameters, and
shapes.
In contrast to additive manufacturing methods that involve adding, layering, and deforming
materials to achieve a specified shape, CNC machining achieves shapes by removing material in
subtractive manufacturing. It also differs from injection molding, where material is injected into a
mold in a different state of matter to form a specified shape.
The versatility of CNC machining spans various materials, including metals, plastics, wood, glass,
foam, and composite materials, making it a widely embraced choice for efficient and precise
fabrication in diverse industries.
Product Details
The primary focus of the CNC machining process revolves around metals, incorporating alloy steel,
carbon steel, cast iron, stainless steel, aluminum, copper, magnesium, and zinc.
Nevertheless, CNC machining extends its capabilities beyond metals to encompass plastic parts
and other materials, including ceramics, composites, thermoplastics, and thermosets.
| Common Materials for CNC Machining | |
| Material | Properties |
| Aluminum | 2024: Good fatigue resistance and strength; excellent toughness at moderate to high strength levels; improved fracture toughness |

| Stainless Steel | Excellent machinability and outstanding uniformity; good workability and weldability, high ductility and formability |
| Steel Alloy | Mix of chromium, molybdenum, and manganese yields toughness, good torsional and fatigue strength |
| Steel Mild Low Carbon | High machinability and weldability, high stiffness; good mechanical properties, machinability, and weldability at low cost |
| Titanium | Excellent strength to weight ratio, used in aerospace, automotive, and medical industries |
| ABS | Excellent impact resistance, good mechanical properties, susceptible to solvents |
| Nylon | Excellent mechanical properties, high toughness, poor moisture resistance |
| POM | High stiffness, excellent thermal & electrical properties, relatively brittle |
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.

FAQ's
1. What are the minimum and maximum dimensions you can machine?
Our CNC machining services encompass CNC milling (3-axis, 3+2-axis, and 5-axis) as well as
turning. For 3/3+2-axis CNC milling, we can machine parts with dimensions up to
2000 x 1500 x 200 mm (78.7 x 59.0 x 7.8 in.). In the case of 5-axis milling, the maximum part size
is 650 x 650 x 300 mm (25.5 x 25.5 x 11.8 in.).
For CNC turning, we can handle parts with a maximum diameter of 431 mm (17 in.) and a length
of 990 mm (39 in.). Recommended minimum part dimensions are approximately 10 x 10 x 10 mm
(0.39 x 0.39 x 0.39 in.), and feature dimensions should not go below 0.5 mm.
It's important to note that our platform has a limitation of a maximum part size of 1000 mm
(39 in.). If your project requires dimensions beyond this limit, please contact our sales team to
discuss your specific needs.
2. What industries do you typically work in? Who are your typical customers?
Our clientele encompasses a wide range of industries, including heavy equipment manufacturing,
general commercial businesses, and companies in industrial, transportation, medical, and consumer
sectors, among others.
Operating on a global scale, our customers are located in the United States, Europe, and various
parts of the world. The common thread among our diverse clientele is the shared need for
precision-machined parts that meet specifications, are delivered punctually, and stay within
