Machining Services
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.

| Common Stainless Steel Materials |
| No. | Properties |
| Stainless steel 304/304L | Stainless steel 304L (CNC) has excellent mechanical properties and
good machinability. Resistant to most environments and corrosive
media. |
| Stainless steel 316/316L | Stainless steel 316L (CNC) has similar mechanical properties to
304, with higher corrosion and chemical resistance. Ideal for
marine applications. |
| Stainless steel 303 | Stainless steel 303 (CNC) has excellent toughness, but lower
corrosion resistance than 304. Ideal for high volumes, due to its
excellent machinability. |
| Stainless Steel 17-4 PH | Stainless steel 17-4 (CNC) - SAE grade 630 - is a precipitation
hardening alloy with good corrosion resistance. Can be hardened up
to 44 HRC. |
| Stainless steel 416 | Stainless steel 416 is magnetic and has a high machinability. |
| Stainless steel 2205 Duplex | Stainless steel 2205 Duplex (CNC) is the alloy with the highest
strength and hardness. Suitable for applications in severe
environments up to 300°C. |
| Stainless steel 420 | Stainless steel 420 provides high strength and corrosion
resistance. It is the hardest of all stainless steels when
hardened. |
| Stainless steel 440C | Stainless steel 440C has improved toughness and corrosion
resistance due to Carbon and Chromium content. |
| Stainless steel 430 | Stainless steel 430 is magnetic and corrosion resistant. |
| Stainless steel 301 | Stainless steel 301 is corrosion resistant similar to Stainless
steel 304. |
| Stainless steel 15-5 | Stainless steel 15-5 has a higher toughness than 17-4, better
corrosion resistance and transverse properties compared to other
similar martensitic grades. |

Company Profile
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.
