CNC machining, or computer numerical control machining, stands as a widely utilized
manufacturing process employing automated, high-speed cutting tools to shape designs from
metal or plastic stock.
Standard CNC machines encompass 3-axis, 4-axis, and 5-axis milling machines, lathes, and
routers. The methodology for cutting CNC parts may vary across machines—where the workpiece
or the cutting tool may move independently or in unison.
Skilled machinists proficiently operate CNC machines, programming tool paths based on the final
machined parts' geometry. CAD (computer-aided design) models furnish the necessary part
geometry information.
CNC machines exhibit the capability to precisely and repeatedly cut various metal alloys and
rigid plastics, making custom machined parts applicable across diverse industries such as
aerospace, medical, robotics, electronics, and industrial.
Product Details
Materials for CNC machining are typically classified into three major categories:
plastics, soft metals, and hard metals. Examples encompass aluminum, bronze, copper,
ceramics, plywood, steel, stone, wood, zinc, and various others.
Materials characterized by ease of manipulation and favorable properties are commonly
preferred over alternative options.
Here is a comprehensive overview of the most popular materials
| The Most Popular Materials | |
| Material | Characteristics |
| Aluminum 6061 | Good strength-to-weight ratio, excellent machinability, low hardness |

Specialist Industries
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.
Company Profile
FAQ's
1. What is the typical turnaround time for a quotation?
In the majority of instances, we aim to provide a response within a few days of receiving a
Request for Quotation (RFQ). Should there be any delay in the quoting process, we commit to
notifying you at the earliest convenience.
2. How can I be assured that my design will be treated confidentially?
We take confidentiality seriously and are willing to sign and uphold any non-disclosure or
confidentiality agreement.
Additionally, our factory strictly prohibits the taking of photographs of a customer's product
without explicit permission. Ultimately, our commitment to preserving your design's confidentiality
is reinforced by our longstanding reputation, having worked with hundreds of thousands of unique
designs over many years, without ever divulging proprietary information to third parties.
3. How does compare to other suppliers in terms of price?
While direct comparisons can be challenging, We generally offers prices that are typically 25-45%
lower for plastic injection mold tools and CNC machined/turned parts when compared to suppliers
in North America and Europe.
In contrast to Chinese suppliers, our strategy is not to compete solely on price. Instead, we
prioritize delivering the highest levels of quality, swift response times, and professional results.
4. What is the turnaround time for receiving my parts?
High-quality parts can be manufactured in as little as two weeks if you furnish us with comprehensive
2D and 3D CAD models. However, more intricate parts with special features or requirements may
necessitate a longer production time. To obtain more precise lead times tailored to your project,
please request a quote.
Regarding shipping, the majority of our shipments are handled via air freight, taking a few days for
delivery from China to Europe or North America.
