Mechanical CNC Milled Parts

CNC milling involves the use of automated cutting machines equipped with a rotating

spindle-head to remove unwanted material.

These machines come in various sizes and configurations, allowing for versatile applications.

While CNC milling is commonly employed for cutting tougher metals, it can also handle materials

ranging from plastics and aluminum to stainless steel and titanium.

Product Details

Materials Commonly Used in CNC Milling

CNC milling encompasses a wide range of materials, with three main categories: plastics, soft metals,

and hard metals.

These materials are versatile and suitable for various machining applications. Examples of materials

used in CNC milling include aluminum, bronze, copper, ceramics, plywood, various types of steel,

stone, wood, and zinc, among others.

Certain materials, such as aluminum and mild steel, are favored by machinists due to their ease of

workability and excellent properties, making them industry standards for many applications.

Application for CNC Milling Parts

CNC machining is a go-to manufacturing process to get precision parts, whether for prototyping

or end-use production.

It is widely used throughout the aerospace, medical, automotive industries for its ability to

rapidly manufacture precise parts in production-grade materials, such as:

1. housings and enclosures
2. brackets
3. fixtures for manufacturing
4. gears and bearings
5. internal mechanical components
6. medical instrumentation

FAQ's

1. How do you get the most out of CNC milling?

Efficiency and cost-effectiveness in CNC milling can be achieved through various strategies,

primarily centered on designing parts that are "Simple" and adhere to "Standard" specifications.

When you design parts with straightforward features that can be manufactured using

standard-sized tools, you enhance the likelihood of successful outcomes.

While complexity has its place in certain situations, it typically results in longer lead times and

increased costs.

For example, a part with intricate features may pose manageable challenges when crafted from

aluminum but may become considerably more complex and costly when produced from plastic,

especially in mass production scenarios.

In summary, prioritize simplicity and standardization in your designs whenever possible.

While there may be instances where complexity or specialized materials are warranted, be mindful

that they can significantly impact the milling process in terms of intensity and cost.

2. Design Considerations for CNC Milling

When designing parts for CNC milling, consider the following guidelines:

1. Leverage Precision: CNC milling machines offer high precision, so take advantage of this

capability in your designs.

2. Avoid Deep Pockets: Deep pockets can be challenging to machine, so try to minimize their use.

3. Address Sharp Inside Corners: Sharp inside corners can pose machining difficulties, so consider

using radii to ease machining.

4. Apply Chamfers: Add chamfers to top edges to reduce sharpness, improve aesthetics, and f

acilitate machining.

5. Implement Fillets: Apply fillets to the bottom of pockets to reduce the risk of stress fractures,

especially if the component will be subjected to stress.

6. Be Cautious with Thin Walls: Thin walls and delicate shapes may be challenging to machine,

as they might not withstand the cutting pressure.

7. Simplify Curves: When possible, design shapes that do not involve complex curves in multiple

axes, as they can be tricky to hold during machining processes.
