CNC machining, standing for Computer Numerical Control machining, is a subtractive
manufacturing process utilized to fabricate parts by selectively removing material from a workpiece
or workpiece stock.
Precise control over the machine's movements is achieved through preprogrammed software and
codes. The scope of CNC machining encompasses various machinery types, including turning mills,
lathes, grinders, and plasma-cutting machines.

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. Why choose CNC machining?
The Swift and Precise World of 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.
3. 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.
