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machining is still relevant, CNC machining has largely superseded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
The primary focus of the CNC machining process revolves around
metals, incorporating alloy steel,
carbon steel, cast iron, stainless steel, aluminum, copper,
magnesium, and zinc.
Nevertheless, CNC machining extends its capabilities beyond metals
to encompass plastic parts
and other materials, including ceramics, composites,
thermoplastics, and thermosets.

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.

a uniform base size.
Therefore, customers should be ready to receive tools of that size
to ensure compatibility with
their machines.
2. 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
and surpass reasonable expectations.
3. 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.
4. What are the minimum and maximum dimensions you can machine?
Our CNC machining services cover a range of processes, including
milling (3-axis, 3+2-axis, and
5-axis) and turning. In 3/3+2-axis CNC milling, we can machine
parts with dimensions up to
2000 x 1500 x 200 mm (78.7 x 59.0 x 7.8 in.). For 5-axis milling,
the maximum part size is
