CNC machining, distinct from traditional machining, accomplishes the same metal cutting, drilling,
milling, boring, grinding, and other metal forming and removal functions, but with the key
difference of utilizing computer numerical control instead of manual operation by a skilled machinist.
Traditional machining involves a manual approach where a machinist operates the machine, removing
or forming metal based on specifications from designers and engineers.
This process employs various tools such as turn wheels, dials, switches, chucks, vices, and cutting
tools made of materials like hardened steel, carbide, and industrial diamond.
In CNC machining, the automated process is driven by code developed by programmers, ensuring
consistent precision from the first cut to subsequent repetitions.
Commonly used in digital manufacturing and occasionally in low-volume production, CNC machining
allows for easy revisions and alterations for modifications and diverse materials. While traditional
machining is still relevant, CNC machining has largely superseded it in manufacturing, fabrication,
and industrial production due to its enhanced precision and automation.
Product Details
CNC machines excel at cutting a wide range of materials, including aluminum, bronze, copper,
ceramics, plywood, various steel types, stone, wood, zinc, and numerous engineering materials.
This versatility makes them perfect for crafting prototypes during product development.
With CNC milling, you can easily fine-tune and make precise adjustments until you achieve the
desired final product, offering accuracy and efficiency throughout the manufacturing process.

Specialist Industries
CNC turning machines, known for their adaptability, generate a diverse range of parts with
varying complexities. This includes the production of shafts and axles, crucial in industries such as
automotive and aerospace.
Precision-engineered bushings and bearings, essential for smooth rotational movement in
mechanical assemblies, are also within the capabilities of CNC turning. The versatile nature of
CNC turning extends to crafting connectors, fittings, fasteners like screws and bolts, as well as
intricate valve components for fluid control systems.
Moreover, CNC turning contributes to the creation of tooling components such as inserts, toolholders,
and bodies, enhancing efficiency in machining operations. In the automotive realm, CNC turning is a
key player in manufacturing engine components, pulleys, brackets, and specialized parts.
Company Profile
FAQ's
1. What cosmetic standards do you guarantee?
Upholding stringent quality standards, our CNC machined parts undergo standard deburring and
edge-breaking procedures. Clear indications in technical drawings are required for any critical
edges that should be left sharp.
Surfaces are guaranteed to be defect-free, ensuring the absence of scratches, dents, stains,
blemishes, hanging marks, and minor imperfections. Critical surfaces (primary (a) side, as outlined
in technical drawings) will be meticulously free from mill steps and other marks. On the secondary
(b) side, minor hanging marks and up to 2 minor defects are considered within acceptable limits.
Additionally, a range of post-processing and finishing methods can be applied to enhance surface
roughness, visual aesthetics, and wear resistance for CNC machined parts.
2. How much does CNC machining cost?
The cost of CNC machining is determined by factors such as complexity, quantity, and lead time.
To obtain a precise cost estimate, we encourage you to submit a 3D CAD model, enabling us to
provide an interactive quote accompanied by design for manufacturability (DFM) feedback.
Our use of proprietary software and automated fixturing processes eliminates upfront non-recurring
engineering (NRE) costs, making CNC machining a cost-effective choice for quantities as low as 1 to
200 parts. While prices may be comparable or slightly higher than 3D printing, CNC machining
delivers superior material properties and surface finishes.
3. How does compare to other suppliers on price?
Unlike Chinese suppliers who often compete on price, We chooses a different approach. While our
prices may not be the lowest, we prioritize delivering the highest levels of quality, rapid response,
and professional results, setting us apart in the market.
