Custom CNC Turning Products Black CNC Parts Machining Aluminum Part

CNC machining operates on subtractive processes, where the feedstock is machined to its final

form through the removal of material. This includes activities such as drilling holes, boring lots

and pathways, and shaping metal stock into new material with varying tapers, diameters, and

shapes.

In contrast to additive manufacturing methods that involve the addition, layering, and deformation

of materials to achieve a specified shape, CNC machining achieves shapes by subtracting material.

This distinction also separates it from injection molding, where material is injected in a different

state of matter using a mold and formed to a specified shape.

Product Details

The turning process primarily involves the machining of various metals.

These metals encompass a wide range of materials, including alloy steel, carbon steel, cast iron,

stainless steel, aluminum, copper, magnesium, and zinc.

Nevertheless, it is essential to note that the turning process is not limited to metals alone;

it can also be applied to plastic components and a diverse array of materials such as ceramics,

composites, thermoplastics, and thermosetting materials.

CNC Machining Tolerances

Typical machining tolerances fall within the range of ± 0.005 inches or 0.13 millimeters.

Tolerances represent the allowable variation for a specific dimension.

For instance, if a CNC machining tool has a tolerance of ± 0.01 millimeters, it means that the tool

can deviate by 0.01 millimeters in each cut.

When provided with a drawing, Our CNC machining service can achieve CNC parts with tolerances

as tight as ± 0.0002 inches.

In the absence of a drawing, all CNC parts are manufactured according to our ISO 2768 medium

standard. We can also work to even tighter tolerances, such as ± 0.025 millimeters or ± 0.001

inches, when an engineering drawing specifies critical features.

Applications of CNC Turning

CNC machining, being a versatile subtractive manufacturing process, finds extensive application

across a multitude of industries.

Some of the key sectors that heavily rely on CNC machining include:

1. Aerospace: Precision is paramount in aerospace, and CNC machining is instrumental in crafting

intricate components for aircraft and spacecraft, ensuring optimal performance and safety.

complex parts, ranging from engine components to intricate systems, contributing to the efficiency

and reliability of vehicles.

3. Aviation: Similar to aerospace, the aviation industry benefits significantly from CNC machining,

ensuring the manufacturing of high-precision components for aircraft to meet stringent safety and

performance standards.

4. Transportation: Beyond aerospace and automotive, the broader transportation sector, including

rail and maritime industries, relies on CNC machining for the fabrication of critical components that

withstand rigorous operational demands.

These industries highlight just a few examples of CNC machining's widespread utilization.

The technology's ability to deliver accuracy, consistency, and intricate detailing makes it

indispensable in various integral sectors, ensuring the production of high-quality components that

meet the stringent standards of modern manufacturing.

FAQ's

1. 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.

2. Why choose CNC machining?

The choice of CNC machining is characterized by its speed, precision, and versatility.

This manufacturing solution distinguishes itself by efficiently producing end-use parts across various

volumes, all without the necessity for significant investments in hard tooling or elaborate set-ups.

3. Can I use my own material for production?

You are welcome to use your own material for production, provided it is compatible with the

capabilities of our machines.
