CNC machining, standing for Computer Numerical Control machining, is a subtractive
manufacturing technology where material is automatically removed from raw stock according to
computer-generated instructions.
In broad terms, CNC machines are categorized into two types: those that keep the raw stock
stationary while rotating the cutting tool, and those that rotate the raw stock while moving it
against a stationary tool.
Various deviations and combinations of these basic approaches exist, allowing some machines to
employ both techniques simultaneously to produce parts with intricate features.

Specialist Industries
The applications of CNC machining are virtually limitless, offering a myriad of possibilities across
various industries. One notable application is in the woodworking sector, where CNC machines
streamline the production of wooden furniture, saving time and reducing costs.
Complex geometries that would traditionally require a skilled woodworker can now be achieved
efficiently through CNC machining. In lettering and engraving systems, CNC technology is utilized
for marking patterns or text onto surfaces, serving both artistic and serialized part needs.
The electrical industry benefits from CNC machining for tasks such as creating component mounting
holes in printed circuit boards and machining heat sinks for heat-generating electrical components.
Precision equipment for the pharmaceutical industry, including metering pumps, ingredient-dispensing
nozzles, and packaging components, is also manufactured using CNC machines.
Even in the fast-moving consumer goods sector, CNC machining plays a vital role in producing custom
material-handling machinery for the food and beverage industry, as well as contributing to the
fabrication of injection-molded plastic molds used in food packaging.
Company Profile
FAQ's
1. Can make design drawings for me?
Unfortunately, we don't offer an independent product design service. However, for all approved
orders, we provide a Design for Manufacturing review. This involves collaborating with our clients
to enhance their 2D and 3D drawings, ensuring better manufacturability, resolving design conflicts,
and reducing production costs. Learn more about preparing your CAD drawings for manufacturing.
2. What type of design files does We accept for quoting?
For precise and prompt quoting, we exclusively accept 3D CAD files in STL, STEP, or IGES formats.
For 2D drawings with reference dimensions, please submit them in PDF format.
It's essential to include comprehensive manufacturing information as part of your technical
documentation. Informal communication through SMS, Skype, email, etc., will not be deemed
acceptable for manufacturing purposes.
3. How long does a quotation take?
Typically, we aim to respond to Requests for Quotation (RFQ) within a few days of receipt.
In the event of any delays, rest assured that we will promptly notify you of the situation.
4. Can I use my own material for production?
Absolutely, you can use your own material for production, as long as it aligns with the capabilities
of our machines.
5. How do I know my design will be kept confidential?
Rest assured, we are committed to maintaining the confidentiality of your design. We 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 reputation is built on years of working with numerous unique
designs, ensuring that no proprietary information is ever disclosed to third parties.
