CNC Milling Capabilities

CNC milling is a manufacturing process that involves the use of computer-controlled machines to remove material from a workpiece. The machine uses rotary cutters to remove material, creating a specific shape or design on the workpiece. CNC milling machines can be operated in a range of directions, including vertically, horizontally, and even diagonally, depending on the requirements of the project. At our CNC machining shop, we can provide multiple-axis milling services to manufacture precision CNC machined parts. We customize precision CNC parts for CNC prototyping and production.

3 axis milling

3-axis milling uses a cutting tool to remove material from a workpiece in three directions: X, Y, and Z. The machine moves the cutting tool along these three axes to shape the workpiece into the desired form.

In 3-axis milling, the cutting tool can only approach the workpiece from certain angles, limiting the complexity of the parts that can be produced.

4 axis milling

4 axis milling

4-axis milling has an additional rotary axis. This rotary axis can rotate the workpiece around a vertical or horizontal axis, allowing the cutting tool to access different angles of the workpiece.

4-axis milling enables the production of complex parts with curved surfaces, contours, and undercuts that cannot be achieved with 3-axis milling. We can provide 3+4 axis machining services.

5 axis machining

5 axis machining

5-axis milling can enable the cutting tool to approach the workpiece from any angle and orientation, allowing for complex geometries to be machined with high precision.

With this technique, multiple operations can be performed in a single set-up, resulting in faster turnaround times and lower costs for customers.

CNC milling materials

The choice of material is critical in the production of custom metal and plastic parts. It also depends on several factors, such as the intended use of the part, the environment in which it will be used, and the required strength and durability.

Here are some of the most common materials for CNC milling services:

Why Choose Our Custom CNC Milling Services China?

CNC Milling Tolerance

Maximum Dimensions: Our CNC milling machines can accommodate parts up to 2000mm in length, 1000mm in width, and 500mm in height.

Minimum Dimensions: The smallest features we can mill are typically around 0.2mm, but this may vary depending on the material and design requirements.

Threading: We can create internal and external threads using standard thread forms (such as metric and imperial) or custom thread profiles if required.

Tolerances: Our CNC milling machines can achieve tolerances up to +/- 0.005mm, but the actual tolerance achieved may depend on factors such as material, design, and machining complexity.

Finish Tolerances: This refers to the allowable variation in the surface finish of a machined part, including roughness, waviness, and other imperfections. Our common finish tolerances for CNC milling include Ra 6-12 microns (or 250-500 microinches) for standard finishes and Ra 0.4-0.8 microns (or 16-32 microinches) for high-precision finishes.

Radii: We can achieve radii as small as 0.1mm, but this may vary depending on the material and design requirements.

Text: We can add text to parts using engraving or embossing techniques, with a minimum font size of around 1mm depending on the font and material used.

Available for CNC Milling surface finishes

We also offer various surface finishes for CNC metal parts. These finishes can enhance the appearance and functionality of the parts, as well as protect them from wear and corrosion.

anodized aluminum parts


Anodizing is an electrochemical process that creates a protective oxide layer on the surface of the machined part.

black oxide aluminum parts

Black oxide

A chemical process that creates a black oxide layer on the surface of the metal, providing corrosion resistance and enhancing the appearance of the part.

as-machined parts


This is the basic finish that comes straight from the CNC machining process, without any additional treatment or coating.

bead blasted parts

Bead blasted

This finish involves blasting the surface of the machined part with small glass beads or other media to create a uniform, matte texture.

power coated parts

Powder coated

It involves applying a dry powder to the surface of the machined part, which is then baked to create a durable, corrosion-resistant coating.

Electroless Nickel Plating parts

Electroless Nickel Plating

It deposits a layer of nickel onto the surface of the machined part, providing corrosion resistance and wear resistance.

Quality Assurance For CNC Machined Parts

As a CNC machining manufacturer in China, quality control is a top priority. We have implemented strict quality control measures. Throughout the entire CNC milling process, we ensure that our customers receive high-quality products.

quality control

Pre-production inspection. Before production begins, we conduct a thorough inspection of the raw materials to ensure they meet our quality standards. This includes verifying material composition and checking for any defects or imperfections.

Quality checks during production. Our operators perform frequent quality checks during the CNC milling process to ensure the parts meet the correct specifications. This includes measuring critical dimensions and using sophisticated instrumentation and software to verify tolerances.

Post-production inspection. After the parts are machined, our CNC machining company conducts a final inspection to ensure they meet our customer’s requirements. This includes visual inspections, as well as dimensional and functional testing to ensure the parts perform as intended.

CNC Milling Services FAQs

The CNC milling process starts with a design file that is programmed into the machine’s computer. The material is then held in place on the machine bed. And the cutting tool is moved across the workpiece to remove the material and create the desired shape.

The cost of a custom CNC milling project can vary depending on factors such as the complexity of the design, the material, the number of parts required, and the tolerances specified for the project.

Generally, custom CNC milling costs are calculated based on machine time, material cost, and tooling cost. It’s best to request a quote from a trusted CNC machining company to get an accurate estimate for your specific project.

At our CNC machining company in China, we provide competitive pricing. And we provide excellent quality control to ensure that you get high-quality products at a reasonable price.

CNC milling involves moving a cutting tool across a stationary workpiece to remove material and create a desired shape or design. The cutting tool is typically mounted on a rotating spindle and can move along multiple axes to perform complex cuts and shapes.

CNC milling is ideal for creating parts with complex geometries, as well as those that require tight tolerances and high precision.

CNC turning, on the other hand, involves rotating a workpiece while a cutting tool removes material from its surface. The cutting tool is held in a fixed position and moves along one or more axes to create the desired shape or design. CNC turning is ideal for creating cylindrical or rounded parts, such as shafts, tubing, and other components.

In summary, the main difference between CNC milling and CNC turning is the orientation of the cutting tool and workpiece during the machining process. CNC milling is best suitable for complex shapes and geometries, while CNC turning is ideal for creating cylindrical or rounded parts.
