CNC machining, short for computer numerical control machining, represents a subtractive
manufacturing method that relies on the coordination of computerized controls and machine tools.
This process involves the removal of layers from a solid material block, with programming guiding
the desired cuts in the metal. The corresponding tools and machinery then execute the machining
task in an automated fashion.

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. Can make design drawings for me?
While we don't provide a standalone product design service, we do conduct Design for
Manufacturing reviews for all approved orders. This entails working closely with our clients to
optimize their 2D and 3D drawings, addressing design conflicts, and minimizing production costs.
Check out our guidelines on preparing CAD drawings for manufacturing.
2. How quickly can I get my parts?
With complete 2D and 3D CAD models, we can manufacture quality parts in just two weeks.
However, for more complex parts with special features, additional time may be required.
Request a quote for accurate lead times tailored to your project.
Shipping is primarily done via air freight, taking only a few days from China to Europe or North America.
3. How does you ensure the quality of my parts?
After order confirmation, we conduct a thorough Design for Manufacturing (DFM) review to pinpoint
any potential issues that could affect part quality.
Incoming materials undergo rigorous inspection and verification using advanced testing equipment.
Final inspection reports are generated before shipment. Moreover, we provide the capability to share
inspection data in real-time, allowing us to collaborate on addressing any quality concerns that may
arise during the production process.
4. How much import duty will I need to pay for my goods?
The import duty for your goods is not universally fixed, and its calculation depends on several factors.
In Australia, new CHAFTA regulations facilitate a phased introduction of duty-free imports.
Import duties vary widely and are contingent upon the nature of the imported goods.
Internationally, the majority of countries follow the Harmonized System (HS) codes, classifying a
broad spectrum of commercial trade goods.
