The functioning of CNC machining is characterized by subtractive processes, wherein the feedstock
is machined to its final form by the removal of material. This process encompasses activities such
as drilling holes, boring lots and pathways, and shaping metal stock into new material with varying
tapers, diameters, and shapes.
Unlike additive manufacturing methods that involve the addition, layering, and deformation of
materials to achieve a specified shape, CNC machining achieves shapes through the removal of
material. This sets it apart from injection molding, where material is injected in a different state
of matter using a mold and formed to a predetermined shape.
Product Details
Materials for CNC machining are typically classified into three major categories:
plastics, soft metals, and hard metals. Examples encompass aluminum, bronze, copper,
ceramics, plywood, steel, stone, wood, zinc, and various others.
Materials characterized by ease of manipulation and favorable properties are commonly preferred
over alternative options.
| 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 |
| 6061: Excellent machinability, low cost, and versatility | |
| 7075: High strength, hardness, low weight, and heat tolerance | |
| Brass | Versatile and highly attractive copper/zinc alloy with warm yellow color accommodates severe forming/drawing |
| Copper | High ductility and high electrical and thermal conductivity; develops attractive blue-green surface patina over time |
| 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 |

FAQ's
1. Can make design drawings for me?
Unfortunately, we don't offer an independent product design service. However, for all approved
orders, we provide a Design for Manufacturing review. This involves collaborating with our clients
to enhance their 2D and 3D drawings, ensuring better manufacturability, resolving design conflicts,
and reducing production costs. Learn more about preparing your CAD drawings for manufacturing.
2. Can I use my own material for production?
Absolutely, you can use your own material for production, as long as it aligns with the capabilities
of our machines.
3. How do I know my design will be kept confidential?
Rest assured, we are committed to maintaining the confidentiality of your design. We are willing
to sign and uphold any non-disclosure or confidentiality agreement.
Additionally, our factory strictly prohibits the taking of photographs of a customer's product without
explicit permission. Ultimately, our reputation is built on years of working with numerous unique
designs, ensuring that no proprietary information is ever disclosed to third parties.
4. How quickly can I get my parts?
We can produce quality parts in as little as two weeks if complete 2D and 3D CAD models are
provided. However, more intricate parts with special features may require additional time.
For more precise lead times based on your project, request a quote.
Regarding shipping, the majority of our shipments are via air freight, taking only a few days from
China to Europe or North America.
