Custom Precision CNC Parts Stainless Steel Aluminum CNC Machining Parts Turning Milling CNC Service Brass CNC Parts
CNC (Computer Numerical Control) machining is an automated process that involves using a
machine to remove material from raw stock based on computer-generated instructions.
It is applicable to a wide range of materials, from expanded polyurethane foam to nickel
superalloys. Common applications for CNC machining include manufacturing, crafting
ornamental furniture, and producing turbine blades.
The cost of CNC machining is influenced by factors such as precision requirements, surface
finish, quantity, material selection, and the complexity of the part being produced.
Product Details
CNC machining is applied to a wide range of materials, each having its unique optimal machining
parameters (speeds and feeds) to ensure effective material removal.
The most frequently used materials include:
1. Metal
Metal is the most prevalent material in CNC machining. CNC machines can cut virtually any type
of metal, from easily machinable brass to challenging nickel superalloys like Inconel.
Metal machining spans various applications, including injection molds, shafts, and gears.
2. Plastic
Although most plastic parts are made through injection molding, CNC machining is employed for
specific plastic components. Common materials include ABS (acrylonitrile butadiene styrene),
nylon, and polycarbonate.
Plastic machining applications encompass valve bodies, bushings, and prototypes for evaluating
part functionality before investing in costly molding tools.
3. Wood
CNC routers are frequently used for wood cutting and are generally more cost-effective than
standard metal-cutting CNC machines.
Wood CNC machining is primarily employed for decorative purposes. Typical applications
encompass furniture, window frames, and ornamental panels.
4. Foam
Polyurethane foam, whether closed or open-cell, finds extensive use in CNC machining.
Foam blocks can be shaped into secure packaging for high-value products using a CNC router.
One example is the foam employed in toolboxes to securely hold tools during transport.
5. Composites
CNC machines are commonly employed in the processing of composite parts.
Composite materials include a wide range, from aramid to fiberglass to carbon fiber.
These materials are highly abrasive to cutting tools. In aerospace and marine industries,
composite components are machined to add fastener holes and for general trimming post-molding.

Company Profile
FAQ's
1. Can make design drawings for me?
We do not offer standalone product design services, but we do provide Design for Manufacturing
(DFM) reviews for all approved orders.
This means that we collaborate with our clients to optimize their 2D and 3D drawings, enhancing
manufacturability, resolving design issues, and reducing production expenses.
Learn more about preparing your CAD drawings for manufacturing.
2. How long does a quotation take?
Typically, we aim to provide a response within one days upon receiving an RFQ.
If there is a delay in generating the quote, we will promptly inform you.
3. How do I know my design will be kept confidential?
We prioritize the confidentiality of your design through several means:
1. Non-disclosure Agreement (NDA): We are willing to sign and comply with any non-disclosure
or confidentiality agreement you provide.
2. Strict Factory Policy: Within our facility, we have a rigorous policy that strictly prohibits taking
photographs of a customer's product without their explicit consent.
3. Proven Track Record: Over the years, we have built a solid reputation for working with
countless unique designs while safeguarding proprietary information from disclosure to third
parties. You can rely on our track record of maintaining confidentiality and trustworthiness.
4. How does our pricing compare to other suppliers?
When it comes to pricing, making direct comparisons can be challenging.
However, as a general guideline, our prices for plastic injection mold tools and CNC
machined/turned parts are typically 25-45% lower than those of suppliers in North
America and Europe.
In contrast to Chinese suppliers, we prioritize delivering the utmost quality, swift response
times, and professional outcomes, rather than engaging in a price-driven competition.
5. How quickly can I get my parts?
We can produce quality parts in as little as two weeks if you provide us with complete 2D and 3D
CAD models. However, more complex parts with special features may have longer lead times.
Request a quote to receive more precise lead times based on your specific project.
Regarding shipping, our primary method is air freight, which typically takes a few days for
delivery from China to Europe or North America.
