The term CNC, short for computer numerical control, characterizes the technology at the core of
CNC machining, a process where machining operations are guided and managed by a computer.
This computerized approach enables the efficient production of parts with heightened speed,
accuracy, precision, and the capability to achieve intricate geometries beyond the reach of manual
machining.
Moreover, CNC machining diminishes the reliance on manual labor for machining tasks that would
traditionally be performed by humans. While individuals are not directly involved in the physical
machining of each part, their involvement is pivotal in programming and operating CNC machines
to ensure the smooth execution of every operation.

Typical Applications of CNC Turning
CNC turning services are indispensable in several key industries, with a significant impact on
transportation sectors like aerospace, automotive, mass transit, rail and locomotive, military,
and trucking.
Within these realms, CNC machines are instrumental in crafting essential transportation equipment,
ranging from headnuts and gear blanks to bearing blocks, levers, axles, and rotors.
In the construction industry, CNC machines are harnessed to produce robust bolts and screws,
crafted from materials like stainless steel and aluminum, crucial for handling heavy-duty applications.
Furthermore, CNC turning services are pivotal in the manufacturing of diverse auto parts,
encompassing engine components like cylinder heads, connecting rods, and camshafts, transmission
parts including shafts and rings, as well as suspension components like sway bars, control arms,
and tie rod ends.
The aviation sector also benefits significantly from CNC turned parts, utilizing them for the
customization and production of probes, joint connectors, fasteners, and engine and aircraft
components, often opting for titanium due to its resilience to extreme temperatures.

FAQ's
1. Factors Influencing CNC Machining Costs:
The cost of CNC machining a part is influenced by several key factors, including:
1. Material: Variations in material costs arise as some materials, such as aluminum, are more
cost-effective to machine than others like Inconel due to increased tool wear and slower cutting
speeds.
2. Complexity: Parts with intricate features incur higher machining costs. Complex surface shapes,
for instance, are notably more expensive to machine compared to flat surfaces.
3. Tolerances: Stringent dimensional tolerances escalate machining costs. Specifying unnecessarily
tight tolerances on non-critical features can contribute to increased CNC machining expenses.
4. Surface Finish: Achieving mirror finishes necessitates specialized tooling and machining
strategies, extending machining time and subsequently increasing costs.
5. Quantity: Low-volume production inherently comes at a higher cost per part than large-volume
production. This is because initial setup and programming costs are distributed over a greater
number of parts in large-volume production.
2. How long does delivery time and quotation take?
The delivery time for parts is determined by their complexity. Parts with low complexity typically
have a lead time of 2-3 days, while moderate complexity extends the lead time to 2-5 days.
High-complexity parts may require 5 to 15 days for delivery. Quoting time varies based on design
complexity, ranging from 1 business day (or faster) for simpler designs to 3+ business days for
more intricate ones. For an assessment and quote for your design, please feel free to reach out to
our team.
3. How quickly can I get my parts?
We can produce quality parts in as little as two weeks if complete 2D and 3D CAD models are
provided. However, more intricate parts with special features may require additional time.
For more precise lead times based on your project, request a quote.
Regarding shipping, the majority of our shipments are via air freight, taking only a few days from
China to Europe or North America.
