CNC 3 4 5 Axis Aluminum Machining Part Aluminum Alloy CNC Lathe Custom
Processing Machining OEM Turning Milling Compound Parts
CNC machining represents the predominant subtractive manufacturing technology in contemporary
industrial processes.
It stands as an exceptionally flexible and robust method for the production of tailor-made metal and
plastic parts.
Leveraging CAD models, CNC machines execute precise material removal from solid blocks through a
diverse range of cutting tools.
In essence, CNC machining yields components characterized by precise tolerances and remarkable
material properties. Its applicability spans from individual projects to low-to-medium volume
production runs, primarily due to its exceptional repeatability.
Product Details
The choice of raw material directly impacts machining costs.
Different materials have varying costs, availability, and machining characteristics.
High-performance alloys may be more expensive than common metals.
Material availability affects pricing, and considering material type is essential for cost calculation.

FAQ's
1. Where Does CNC Machining Offer the Best Benefits?
CNC machining provides its most significant advantages when the following objectives are a priority:
1. Achieving greater precision in part manufacturing compared to traditional methods.
2. Ensuring consistent and uniform dimensions in the produced products.
3. Scaling up production to meet high volume demands.
4. Crafting intricate and complex designs efficiently.
5. Lowering overall manufacturing expenses.
2. How much import duty will I need to pay for my goods?
The amount of import duty you'll need to pay for your goods can vary depending on various factors,
including your country of import, the type of goods, and their declared value.
Import duties are typically calculated based on international Harmonized System (HS) codes that
classify different trade goods.
These duties vary from country to country and can change over time due to trade agreements
and regulations.
It's essential to check with your local customs authorities or consult a customs broker to determine
the specific import duty rates for your goods in your region.
3. Can you provide passivation for my parts?
We offer passivation as a treatment option that can modify the surface chemistry of certain types of
metals. This process is utilized for purposes such as corrosion protection, enhancing durability,
improving aesthetics, and more.
4. What type of surface finishes does provide?
We provide a diverse range of finishing services to achieve your desired appearance and texture for
your parts.
Our offerings include treatments for metals, texturing for plastic injection mold tools, as well as painting
for both metal and plastic materials, among others.
