CNC Milling is an automated machining process utilized for crafting both 2D and 3D CNC parts

through the subtraction of material from raw stock.

Manufacturing facilities employ CNC milling machines to enhance productivity and reduce

production time.

To create a CNC milled component, a block or sheet material is positioned on a table beneath a

spindle equipped with a cutting tool. A computer controls various parameters, including tool

selection, spindle rotation speed, vertical spindle movement, and horizontal table motion.

This control enables tools like drills, taps, and end mills to remove material sections, shaping

them into desired forms.

CNC Milling stands as a widely adopted manufacturing process known for its precision and

accuracy in crafting CNC parts.

It involves the use of 3D CAD designs, specialized tooling, and machinery like heavy-duty drill

presses and CNC machines to produce customized 3D CAD models.

This process caters to a broad range of materials, including plastic and metal, while maintaining

strict tolerances and impeccable surface finishes.

It is employed in both prototyping and mass production scenarios, allowing for intricate designs

and high-precision CNC parts to be fabricated swiftly.

Additionally, CNC Milling facilitates the creation of components with specific surface finishes,

ensuring uniformity that adheres to precise specifications and tolerances.

Product Details

In the realm of custom milling projects, almost any metal or plastic that possesses sufficient

hardness for machining can be effectively processed.

Among the materials frequently employed in precision CNC machining at CNC machine shops,

aluminum alloys stand out, owing to their inherent resistance to corrosion.

Aluminum is a prevalent choice for CNC milling machine prototypes due to its robustness and

machinability, facilitating the accurate creation of intricate features in a single prototype.

Within milling machine shops, the 6000 series of aluminum alloys is commonly encountered.

Stainless steel alloys also find widespread use, given their corrosion and wear resistance

properties, along with materials like carbon steel, titanium, and nylon. Nylon, in particular,

is valued for its chemical resistance, strength, durability, and thermoplastic characteristics.

CNC Machining Tolerances

Tolerances are not standardized across all processes and materials.

The final tolerances on your part depend on various factors, such as part size, design complexity,

the number and size of features, materials used, surface finish, and the manufacturing process

employed.

Once your order is confirmed, we conduct a Design for Manufacturing review to identify areas that

may need modification for better manufacturability.

It's helpful if you can specify which areas in your design have critical tolerances that must be met

and which can be adjusted, if necessary, to optimize production time and cost.

Common Applications of CNC Milling Parts

Parts and products produced through CNC machining find application in many industries,

including, but not limited to, the following:

Designing Parts for CNC Milling: Best Practices

When designing parts for CNC milling, several key factors should be considered to optimize the

manufacturing process.

Here are some best practices recommended by our in-house team of mechanical engineers:

1. Minimize Set-Ups: Aim to reduce the number of setups required for creating a part.

Minimizing setups enhances the speed and efficiency of the milling process.

2. Internal Corner Radii: Add internal corner radii to the parts, with a minimum radius of

1/4 the depth of the cut and preferably around 1/2 the depth of the cut

(or as large as the design allows) for cost savings.

Whenever possible, minimize pocket depth and consider using drilled holes instead of milling shapes.

3. Avoid Thin Walls and Sections: Milling forces can cause deflection and warping, even with

soft metals. Avoid unnecessary thin sections in your part design.

By doing so, you can accelerate production, reduce costs, and enhance the surface finish of

the workpiece.

4. Consider Part Size: Smaller features may require smaller, more delicate tools.

These small tools are less efficient and run at slower speeds, which can increase costs.

If a feature doesn't need to be small for the part to function properly, opt for a larger size.

5. Standardize Everything: Utilize standard thread sizes, corner radii, materials, and tolerances

whenever possible.

Standardization helps save costs and ensures timely production, regardless of the manufacturer.

By following these best practices, you can design parts that are well-suited for CNC milling,

resulting in efficient manufacturing and high-quality finished products.
