Machined Parts
CNC, an acronym for computer numerical control, defines the
technology behind CNC machining,
where various machining processes are directed and controlled by a
computer.
This computerized automation facilitates the production of parts
with increased speed, accuracy,
precision, and the ability to achieve more complex geometries
compared to manual machining
methods.
Additionally, CNC machining reduces the need for labor-intensive
manual machining tasks that
would otherwise be carried out by humans. Although individuals are
not physically machining each
part, their role is crucial in programming and operating the CNC
machines, ensuring the seamless
execution of every operation.
Product Details
In the realm of CNC machining's turning process, metals take center
stage, boasting a diverse
lineup that includes alloy steel, carbon steel, cast iron,
stainless steel, aluminum, copper,
magnesium, and zinc.
However, the CNC turning process extends its reach beyond metals,
showcasing its flexibility by
seamlessly machining plastic parts. Furthermore, CNC turning proves
its adaptability by working
with an array of materials such as ceramics, composites,
thermoplastics, and thermosets.
This broad material compatibility underscores the capability of CNC
turning to meet the intricate
demands of various manufacturing applications.

FAQ's
1. Why choose CNC machining?
The choice of CNC machining is characterized by its speed,
precision, and versatility.
This manufacturing solution distinguishes itself by efficiently
producing end-use parts across
various volumes, all without the necessity for significant
investments in hard tooling or
elaborate set-ups.
2. How long does delivery time and quotation take?
The delivery time for parts is intricately tied to their
complexity. Low-complexity parts usually
have a lead time of 2-3 days, while moderate complexity extends to
2-5 days. High-complexity
parts may necessitate a lead time ranging between 5 and 15 days.
Quoting time is also linked to design complexity, ranging from 1
business day or faster for
simpler designs to 3+ business days for more intricate ones. If you
have a design that requires
assessment and quoting, do not hesitate to contact our team.
3. What are the advantages of CNC machining?
CNC machining offers a spectrum of advantages, prominently
featuring rapid prototyping and
the expedited production of full-scale parts. Its hallmark is the
ability to achieve exceptional
precision and accuracy in manufacturing, catering to tight
tolerances for CNC parts of diverse
sizes.
This method stands out for its flexibility, influencing factors
such as volume, pricing, lead times,
and the array of materials and finishes available.
4. What are standard machining tolerances?
Standard machining tolerances are set at ± 0.005" or 0.13mm,
delineating the acceptable range
for dimensions. For example, if a CNC machining tool carries a
tolerance of ± 0.01 mm, it signifies
a permissible deviation of 0.01 mm in each cutting operation.
Leveraging a provided drawing, our CNC machining service can attain
part tolerances as precise
as ± 0.0002 in. In cases where no drawing is available, all CNC
parts adhere to our ISO 2768
medium standard.
Projects requiring even tighter tolerances, such as ±0.025mm or
±0.001", can be accommodated
with an engineering drawing specifying critical features.
