CNC Precision Milling Service Custom Stainless Steel Parts Milled Machining Parts

CNC Aluminum Machining Parts

CNC milling is a manufacturing technique that employs rotating cutting tools to selectively

remove material from a workpiece, shaping it into finished parts and products.

This versatile process is well-suited for a wide range of materials, spanning metals, polymers,

wood, and glass. Typically, CNC milling systems feature 3 linear degrees of freedom—

encompassing the X, Y, and Z axis—yielding exceptional precision and intricate detailing.

Product Details

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.

FAQ's

1. Why choose CNC machining?

CNC machining is a rapid, precise, and adaptable manufacturing process.

It stands out as a manufacturing solution that can deliver end-use parts efficiently, regardless

of the production volume, without the necessity of investing in costly hard tooling or elaborate

setups.

2. What size of fillets are added when no specific fillet is specified by the 3D model

or drawing?

When specific fillet dimensions are not provided, we will apply fillet radii that facilitate machining,

as determined by our machinists' judgment.

If you require a particular fillet radius, please ensure it is specified. In the absence of specific

details, typical internal vertical edge radii may exceed 1/3 of the depth, while internal horizontal

edges can be either left sharp or have a radius ranging from 0.5mm to 1mm, depending on the

machining requirements.

3. A quick guide to CNC machining parameters

Many of the crucial machining parameters are established by the machine operator during the

generation of G-code. Among the primary parameters we will discuss are the CNC machine's build

size and its precision.

CNC machines are equipped with a relatively spacious build area, particularly when compared to

3D printers. CNC milling systems are capable of machining parts with dimensions of up to

2,000 x 800 x 100 mm (78” x 32” x 40”), while CNC turning systems excel at machining parts

with diameters reaching up to Ø 500 mm (Ø 20’’).

CNC machining empowers the creation of components with exceptional accuracy and stringent

tolerances. These machines are capable of achieving tolerances even finer than half the diameter

of an average human hair, with a precision of ± 0.025 mm or .001’’.

In cases where tolerances are not explicitly specified in the technical drawings, operators typically

machine the part with an accuracy of 0.125 mm (.005’’).

4. How much do CNC machining materials cost?

The cost of materials in CNC machining can fluctuate significantly due to the extensive array

of available options.

Each material carries its unique price tag, and the inherent physical properties of each material

play a substantial role in determining machining costs.

For those seeking to manufacture metal components, Aluminum 6061 stands out as the most

cost-effective choice. On the other hand, ABS ranks as the most budget-friendly option among

materials.

As for the influence of machining complexity on costs, stainless steel serves as an illustrative

example. Its inherent hardness, surpassing that of aluminum, renders it more challenging to

machine, consequently elevating the overall machining expenses.
