The optimal application of CNC machining is found in one-off manufacturing tasks and in
low-to-medium volume production scenarios, typically ranging from several hundred to
1000 parts.
For cost-effectiveness, particularly in the production of metal prototypes, CNC machining is
highly recommended. Additionally, when parts demand stringent tolerances, choosing CNC
machining becomes imperative for achieving precision.
Product Details
The primary materials employed in the CNC machining process are predominantly metals.
These metals encompass alloy steel, carbon steel, cast iron, stainless steel, aluminum, copper,
magnesium, and zinc.
However, CNC machining is not limited to metals alone; it is also capable of machining plastic
parts and working with various materials, including ceramics, composites, thermoplastics,
and thermosets.

Typical Applications of CNC Turning
CNC turning machines, known for their adaptability, generate a diverse range of parts with
varying complexities. This includes the production of shafts and axles, crucial in industries
such as automotive and aerospace.
Precision-engineered bushings and bearings, essential for smooth rotational movement in
mechanical assemblies, are also within the capabilities of CNC turning. The versatile nature of
CNC turning extends to crafting connectors, fittings, fasteners like screws and bolts, as well as
intricate valve components for fluid control systems.
Moreover, CNC turning contributes to the creation of tooling components such as inserts,
toolholders, and bodies, enhancing efficiency in machining operations. In the automotive realm,
CNC turning is a key player in manufacturing engine components, pulleys, brackets, and
specialized parts.

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. 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.
3. How do I know my design will be kept confidential?
Your design's confidentiality is paramount to us. We are willing to sign and strictly adhere to any
non-disclosure or confidentiality agreement. Moreover, our factory has a stringent policy against
taking photographs of a customer's product without explicit permission.
Our reputation is founded on years of experience working with a multitude of unique designs,
and we have never allowed any proprietary information to be disclosed to third parties.
4. What type of surface finishes does provide?
Our services encompass a wide array of finishing options to attain the desired appearance and
texture for your parts. We offer treatments for metal, texturing specifically for plastic injection
mold tools, and painting for both metal and plastic, among other choices. Discover more about
specifying your preferred surface texture in our blog.
