CNC Machining Service Custom CNC Metal Machining Turning CNC Machining

Steel Precision Part

The essence of CNC machining, or Computer Numerical Control machining, lies in its subtractive

manufacturing approach, automatically eliminating material from raw stock based on computer

-generated instructions.

Typically, CNC machines fall into two categories: those that maintain the raw stock in a fixed

position while rotating the cutting tool, and those that rotate the raw stock while maneuvering

it against a stationary tool.

Numerous adaptations and hybrid methods exist, enabling certain machines to utilize both

techniques concurrently, facilitating the production of parts with complex features.

FAQ's

1. What cosmetic standards do you guarantee?

Our commitment to quality includes standard deburring and edge-breaking procedures for all CNC

machined parts. Any critical edges requiring a sharp finish must be explicitly indicated in technical

drawings.

Surfaces are guaranteed to be free of defects such as scratches, dents, stains, blemishes, hanging

marks, and minor imperfections. Critical surfaces (primary (a) side, as specified in technical drawings)

will be void of mill steps and other marks.

For the secondary (b) side, minor hanging marks and up to 2 minor defects are deemed acceptable.

To enhance surface roughness, visual properties, and wear resistance, various post-processing and

finishing methods can be applied to CNC machined parts.

2. How much does CNC machining cost?

The cost of CNC machining is influenced by factors such as complexity, quantity, and lead time.

To obtain an accurate quote, we encourage you to submit a 3D CAD model, allowing us to provide

an interactive quote with design for manufacturability (DFM) feedback.

Leveraging proprietary software and automated fixturing processes, we eliminate upfront

non-recurring engineering (NRE) costs. This makes CNC machining cost-effective for quantities

as low as 1 to 200 parts. While prices may compare similarly or slightly higher than 3D printing,

CNC machining offers superior material properties and surface finishes.

3. A quick guide to CNC machining parameters

Most machining parameters are established by the machine operator during the generation of

G-code.
Build Size of CNC Machines:

CNC machines offer a notably large build area, especially when compared to 3D printers.
CNC milling systems can handle parts with dimensions up to 2,000 x 800 x 100 mm (78” x 32” x 40”).
CNC turning systems can machine parts with a diameter of up to Ø 500 mm (Ø 20’’).

Accuracy and Tolerances:

CNC machining enables the production of parts with high accuracy and tight tolerances.
Tolerances achievable with CNC machines can be less than half the diameter of an average human

hair, reaching ± 0.025 mm or .001’’.
If tolerance is not specified in the technical drawing, the operator typically machines the part with an

accuracy of 0.125 mm (.005’’).

Key Takeaways:

CNC machines excel in both build size and precision, making them suitable for a wide range of

applications.
Operators have the flexibility to set machining parameters based on the specific requirements of

the project.
Understanding the build size and achievable tolerances is crucial for designing parts that meet

precision and accuracy standards.
