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

CNC Milling is a widely adopted manufacturing method renowned for its precision and accuracy.

It involves the use of a 3D CAD design, tooling, and machining equipment like heavy-duty drill

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

This process can produce CNC parts from materials such as plastic, metal, and others,

achieving tight tolerances and impeccable surface finishes.

CNC milling serves both prototyping and production needs, accommodating intricate designs

and delivering high-precision CNC parts that meet precise specifications and tolerances in a short

timeframe.

Additionally, it can produce parts with specified surface finishes, ensuring uniformity that aligns

with exact requirements and tolerances.

Application for CNC Milling Parts

CNC Milling parts are widely used in a slew of industries, including aerospace, defense, robotics,

oil & gas, medical technology, research and more.

FAQ's

1. What is your typical lead time? Can my parts be produced urgently?

Our standard lead time for screw machine products, from quoting to manufacturing and shipping,

is approximately one week, with an on-time delivery rate of over 99%.

Depending on factors like tooling, gauges, and material availability, we might accommodate

expedited production for your parts. Feel free to inquire!

2. What are your tolerances for machined parts?

Our tolerances for machined parts are typically within +0.005"/-0.005" for most metal geometries,

and within +/- 0.010" for plastics. However, tolerances may vary for larger parts, especially

when maintaining flatness over extensive sections post-heat treatment.

Regarding the finish requirements, an "As Milled" finish should have a minimum of 125 surface

finish for CNC parts.

For all fabricated parts, there is a dimensional tolerance of 0.010" and an angular tolerance of 1°.

Please note that tapped holes not explicitly indicated as features in the provided CAD model may

be machined to the specified diameters in that model.

Additionally, surface treatments like anodizing, bead blasting, iriditing, powder coating, etc.,

will only be applied if they have been paid for and explicitly acknowledged in advance.

3. How do you design parts for CNC milling?

Creating parts for CNC milling involves careful design considerations. Our team of mechanical

engineers recommends the following essential guidelines:

1. Minimize Set-ups: Reducing the number of setups required for a part streamlines the milling

process, enhancing efficiency.

2. Internal Corner Radii: Include internal corner radii in your designs, preferably at least 1/4 the

depth of the cut, or ideally around 1/2 the depth (if feasible) for cost-effectiveness.

Whenever possible, opt for drilling holes instead of milling shapes to save time and resources.

3. Avoid Thin Walls: Thin sections of a part can warp and deflect due to machining forces, even

with soft metals. If a section doesn't need to be thin, avoid making it so to improve production

speed, reduce costs, and enhance surface finish.

4. Consider Part Size: Smaller features require smaller, more delicate tools that run slower and

increase costs. If a feature doesn't need to be small for functionality, make it larger.

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

to save money and ensure timely part production, regardless of the manufacturer.
