Copper Parts
CNC machining, which stands for computer numerical control machining, is a subtractive
manufacturing technique that involves the integration of computerized controls and machine
tools.
This combination is employed to methodically eliminate layers from a solid material block.
Programmed instructions dictate the desired metal cuts and correspond to specific tools
and machinery, enabling the automated execution of the machining process.

CNC Machining Applications
1. Woodworking Industries:
CNC machining is extensively employed in the woodworking sector, particularly for the production
of wooden furniture. This application offers significant time and cost savings compared to manual
carving, enabling the creation of furniture with intricate geometries that might otherwise require
the expertise of a master woodworker.
2. Lettering and Engraving Systems:
CNC machining is utilized in applications where heavy-duty material removal is not necessary.
Instead, engraving tools are employed to mark patterns or text onto the surface of a part.
This versatile application is used for artistic purposes or for serializing parts.
3. Electrical Industry:
The electrical industry relies on CNC machining for a diverse range of applications.
This includes machining component mounting holes into printed circuit boards and creating
aluminum or copper heat sinks for heat-generating electrical components.
CNC machining ensures precision and efficiency in the production of crucial electrical parts.
4. Pharmaceutical Industry:
CNC machines play a crucial role in the pharmaceutical industry, manufacturing precise
equipment used in the production of pharmaceutical products. Applications range from
extremely precise metering pumps to ingredient-dispensing nozzles and packaging components.
5. Food and Beverage Industry:
CNC machining is integral to the fast-moving consumer goods industry, contributing to the
production of custom material-handling machinery. CNC-machined parts play a crucial role in
enhancing the efficiency and precision of these machines.
Additionally, CNC machining is involved in the creation of injection molds for food packaging,
ensuring high-quality and precisely molded packaging for food and beverage products.

FAQ's
1. Factors Affecting CNC Machining Costs:
The cost of CNC machining a part is contingent on several factors, including:
1. Material: Different materials come with varying costs. Machining materials like Inconel are
pricier due to increased tool wear and slower cutting speeds compared to more economical
options like aluminum.
2. Complexity: Parts with intricate features incur higher machining costs. Complex surface
shapes, for example, contribute to increased expenses compared to simpler, flat surfaces.
3. Tolerances: Tight dimensional tolerance requirements contribute to elevated costs.
Needlessly specifying tight tolerances on non-critical features can increase CNC machining
expenses without added value.
4. Surface Finish: Achieving mirror finishes requires specialized tooling and strategies,
extending machining time and, subsequently, increasing costs.
5. Quantity: Low-volume production is inherently costlier per part due to the spreading of
initial setup and programming costs over a smaller quantity. Large-volume production offers
cost advantages as these setup costs are distributed over more parts.
2. What are standard machining tolerances?
The standard machining tolerance is ± 0.005" or 0.13mm, defining the acceptable range for a
dimension. If a CNC machining tool has a tolerance of ± 0.01 mm, it implies a deviation of
0.01 mm in each cut.
When accompanied by a drawing, our CNC machining service can achieve CNC parts with
tolerances as low as ± 0.0002 in. In the absence of a drawing, all CNC parts are produced
following our ISO 2768 medium standard. Additionally, we have the capability to machine
to tighter tolerances, such as ±0.025mm or ±0.001", when an engineering drawing specifies
critical features.
3. What size of fillets are added when no specific fillet is specified by the 3D model
or drawing?
In cases where a specific fillet radius is not specified in the 3D model or drawing, fillet radii
suitable for easy machining will be added based on the machinist's judgment.
As a general guideline, internal vertical edge radii may exceed 1/3 of the depth, while internal
horizontal edges can either be left sharp or have a radius in the range of 0.5mm to 1mm.
Specific fillet requirements should be indicated if needed.
