Parts Manufacture

CNC machining, standing for Computer Numerical Control machining, is the automated removal

of material from raw stock guided by computer-generated instructions. This process is versatile,

compatible with materials ranging from expanded polyurethane foam to nickel superalloys.

Common applications for CNC machining include fabricating various components, crafting

ornamental furniture, and producing turbine blades. The cost of CNC machining is contingent

on factors such as required precision, surface quality, quantity, material selection, and the overall

complexity of the part.

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.

CNC Machining Applications

CNC milling, known for its precision, stands as a versatile manufacturing technique with

applications across diverse industries. Common uses include:

1. Aerospace Components: Precision machining for the creation of intricate parts crucial for the

aerospace industry, ensuring high standards of reliability.

2. Furniture: Crafting precise components for furniture, ranging from functional elements to

intricately designed pieces.

3. Medical Components: Manufacturing critical parts for medical devices, adhering to stringent

standards of quality and accuracy.

4. Prototypes: Rapid prototyping for product development, allowing efficient testing and refinement

of design concepts.

5. Titanium Pieces: Machining titanium components known for their strength and durability,

commonly used in aerospace, medical, and industrial applications.

6. Woodworking: Precision woodworking for the creation of finely detailed and finished wooden

components for various applications.

These examples illustrate how CNC milling technology caters to a broad spectrum of industries,

offering unparalleled accuracy and flexibility in the production of diverse components.

Company Profile

FAQ's

1. What cosmetic standards do you guarantee?

Upholding stringent quality standards, our CNC machined parts undergo standard deburring and

edge-breaking procedures. Clear indications in technical drawings are required for any critical

edges that should be left sharp.

Surfaces are guaranteed to be defect-free, ensuring the absence of scratches, dents, stains,

blemishes, hanging marks, and minor imperfections. Critical surfaces (primary (a) side, as outlined

in technical drawings) will be meticulously free from mill steps and other marks.

On the secondary (b) side, minor hanging marks and up to 2 minor defects are considered within

acceptable limits. Additionally, a range of post-processing and finishing methods can be applied to

enhance surface roughness, visual aesthetics, and wear resistance for CNC machined parts.

2. What's the general surface texture of CNC milled and turned parts?

In the realm of CNC machining, milled parts typically display a surface roughness of approximately

3.2μm (or 1.6μm for newer machines). In contrast, turned parts exhibit a finer surface texture with

a roughness of 0.8μm. Importantly, this finer surface finish in turning is achieved without the need

for adjusting machining speeds.

3. How does you ensure the quality of my parts?

Upon confirmation of your order, a detailed Design for Manufacturing (DFM) review is carried out to

identify any potential issues affecting part quality. All incoming materials are meticulously inspected

and verified using a suite of testing equipment.

Final inspection reports are generated as part of our pre-shipment quality check. Furthermore, we

offer the option to share inspection data in real-time, enabling collaborative efforts to address any

quality concerns that may emerge during production.
