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.

FAQ's
1. How much do CNC machining materials cost?
The multitude of materials available for CNC machining introduces a range of costs, influenced by
the unique properties and characteristics of each material.
In the realm of metal parts, Aluminum 6061 is a standout for its economical pricing.
If cost efficiency is a priority, ABS takes the lead as the most budget-friendly option.
Importantly, the ease of machining is a key factor impacting costs.
Stainless steel, known for its hardness in comparison to aluminum, presents higher machining
complexities, contributing to an overall increase in costs.
2. How long does delivery time and quotation take?
The lead time for parts is contingent on their complexity. Parts with low complexity typically boast
a lead time of 2-3 days, while moderate complexity extends the lead time to 2-5 days.
High-complexity parts may require a lead time ranging from 5 to 15 days. Quoting time is influenced
by design complexity, with a range of 1 business day (or faster) for simpler designs to 3+ business
days for more intricate ones.

3. What are the advantages of CNC machining?
The advantages of CNC machining are prominent, with rapid prototyping and efficient full-scale
production at the forefront. A distinguishing feature is its capacity for high precision and accuracy
in manufacturing, extending to tight tolerance machining for CNC parts spanning various sizes.
Beyond this, CNC machining offers unmatched flexibility in addressing volume needs, pricing
considerations, lead times, and the utilization of a broad spectrum of materials and finishes.
4. What are standard machining tolerances?
Standard machining tolerances stand at ± 0.005" or 0.13mm, indicating the acceptable range for
dimensions. If a CNC machining tool is specified with a tolerance of ± 0.01 mm, it implies a
permissible deviation of 0.01 mm in each machining operation.
When provided with a drawing, our CNC machining service can achieve part tolerances as fine as
± 0.0002 in. In the absence of a drawing, all CNC parts align with our ISO 2768 medium standard.
Projects demanding tighter tolerances, such as ±0.025mm or ±0.001", can be accommodated with
an engineering drawing outlining critical features.
