Part Machining Stainless Steel

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.

Product Details

CNC machines are employed across a diverse range of materials, each having its optimal set of

machining parameters (speeds and feeds) for successful processing.

The most prevalent materials include:

1. Metal:
Metal stands out as the most frequently utilized material in CNC machining. CNC machines have

the capability to cut nearly any type of metal, from free-machining brass to high-performance

nickel superalloys like Inconel. Metal machining caters to various applications, ranging from injection

molds to the production of shafts and gears.

2. Plastic:
Although the majority of plastic parts are manufactured through injection molding, CNC machining

finds application in producing specific plastic components. Common materials include ABS

(acrylonitrile butadiene styrene), nylon, and polycarbonate.

Plastic machining applications encompass valve bodies, bushings, and the creation of injection

molding prototypes to assess the overall functionality before investing in costly molding tools.

3. Wood:
CNC routers are predominantly used for wood cutting and are generally more cost-effective than

standard metal-cutting CNC machines. Wood CNC machining is commonly employed for decorative

purposes, with applications such as furniture, window frames, and ornamental panels.

4. Foam:
Polyurethane foam, whether closed or open-cell, is frequently employed in CNC machining applications.

CNC routers can cut foam blocks to create secure packaging for high-value products.

An example is the use of foam in toolboxes to ensure the tools remain secure during transportation.

5. Composites:
CNC machines are regularly employed in processing composite parts. Composites may include

materials like aramid, fiberglass, or carbon fiber, which are highly abrasive to cutting tools.

Aerospace and marine composite components undergo machining for tasks such as adding fastener

holes and general trimming after the molding process.

Post-processing and surface finishes for CNC machining

CNC-machined parts as they emerge from the machine often exhibit visible tool marks,

a feature that may not align with your specific part requirements.

Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the

surface appearance and elevating attributes such as wear resistance, corrosion resistance,

and chemical resistance.

Methods like anodizing, bead blasting, and powder coating present viable options for refining

the final presentation of your custom parts, allowing you to achieve the desired surface

quality and performance characteristics.

Specialist Industries

CNC machining stands out as one of the most accurate manufacturing techniques, making it an

ideal choice for the creation of complex designs. Its precision and versatility enable the production

of a wide range of products, including:

1. Aerospace Components:
CNC machining is extensively used in the aerospace industry to manufacture intricate and precise

components for aircraft and spacecraft.

2. Furniture:
In the furniture industry, CNC machining allows for the creation of intricate and precisely crafted

furniture pieces, enhancing design possibilities.

3. Medical Components:
The medical industry benefits from the accuracy of CNC machining in the production of complex

components for medical devices and equipment.

Company Profile

FAQ's

1. What type of design files does We accept for quoting?

To ensure precision and promptness in our quoting process, we exclusively accept 3D CAD files in

STL, STEP, or IGES formats.

For 2D drawings with reference dimensions, please provide them in PDF format.

Complete manufacturing information is crucial and should be included as part of the technical

documentation. Informal communication through SMS, Skype, email, etc., will not be deemed

acceptable for manufacturing purposes.

2. How does the pricing of We stack up against other suppliers?

Although making direct comparisons is not straightforward, We's prices are usually 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.

3. How fast can I expect to receive my parts?

Assuming you provide us with complete 2D and 3D CAD models, we can produce high-quality parts

in as little as two weeks. However, for more complex parts that require additional features, the

production timeline may extend. For accurate lead times based on your project, please request a quote.

In terms of shipping, our primary mode is air freight, typically taking a few days for transit from China

to Europe or North America.

4. How do you guarantee the quality of my parts?

Upon confirmation of your order, we conduct a comprehensive Design for Manufacturing (DFM) review

to identify any potential issues that our engineers believe could impact the quality of your parts.

Our process includes:

Thorough inspection and verification of all incoming materials using a range of testing equipment.
Generation of final inspection reports before shipment.
Furthermore, we offer real-time sharing of inspection data, providing you with the opportunity to

collaborate with us in addressing any quality issues that may arise during production.
