CNC machining, or Computer Numerical Control machining, constitutes a subtractive manufacturing
method employed for the creation of parts through the removal of material from a workpiece or
workpiece stock.
The machine's movement is controlled by preprogrammed software and codes, guiding the precision
of material removal. This versatile process encompasses various machinery, including turning mills,
lathes, grinders, and plasma-cutting machines.
Product Details
CNC machining is a versatile process applied to a diverse range of materials, each requiring specific
machining parameters for optimal results.
The following are some of the most common materials utilized in CNC machining:
1. Metals
Metals stand out as the primary material for CNC machining. CNC
machines exhibit the ability to
cut a wide array of metals, ranging from easily machinable brass to high-performance nickel
superalloys like Inconel.
Metal machining finds applications across various industries, including the production of injection
molds, shafts, and gears.
2. Plastics
Although injection molding is prevalent for plastic parts, CNC
machining plays a role in producing
specific plastic components. Common plastic materials include ABS, nylon, and polycarbonate.
CNC machining applications for plastics encompass the production of valve bodies, bushings, and
prototypes for injection molding feasibility assessments.
3. Wood
CNC routers, often more cost-effective than standard metal cutting
CNC machines, find frequent
use in cutting wood. Wood CNC machining is commonly employed for decorative purposes,
with applications spanning from furniture manufacturing to crafting window frames and
ornamental panels.
4. Foam
Polyurethane foam, available in closed or open-cell forms, is a
popular material for CNC
machining. CNC routers excel in cutting foam blocks to create custom packaging for high-value
products. For instance, toolboxes may feature foam inserts that secure tools during transportation.
5. Composites
CNC machines play a crucial role in processing composite materials,
which can range from aramid
to fiberglass and carbon fiber. Despite being abrasive to cutting tools, CNC machining is employed
in aerospace and marine industries to add fastener holes and trim composite components after
the molding process.
Here is a comprehensive overview of the most popular materials.

Company Profile
FAQ's
1. Do you offer Quick-Turn CNC Machining?
Absolutely! We provide rapid turnaround times for quick-turn parts, with many available in just
3-4 days. Additionally, we offer an expedite option, and our dedicated team collaborates closely
with you to meet your most urgent deadlines.
2. Can passivate my parts?
Passivation is a treatment that alters the surface chemistry of certain types of metals. We provide
passivation services for corrosion protection, enhanced durability, improved aesthetics, and more.
3. How much import duty will I need to pay for my goods?
The specific import duty for your goods varies, and there isn't a one-size-fits-all answer.
For customers in Australia, new CHAFTA regulations enable a gradual implementation of duty-free
imports.
Import duties are diverse and contingent on the type of goods being imported. Globally, most
countries adhere to international Harmonized System (HS) codes, categorizing almost all commercial
trade goods.
4. What if I am not completely satisfied with the parts I receive?
Our commitment extends to guaranteeing the quality of our materials and workmanship in
accordance with the terms specified in the initial order and the information supplied by you.
Any disputes arising from subjective assessments will be addressed by our management, which
will make every effort in good faith to ensure your complete satisfaction.
The foundation of our ongoing business is built on earning your confidence in our capacity to meet
