What is CNC Milling & CNC Milling at XY-Global

CNC Milling is a high-precision, subtractive manufacturing process that utilizes computerized controls to shape solid material into complex three-dimensional parts. It is highly versatile, capable of creating flat surfaces, slots, holes, and intricate contours in virtually any material, making it ideal for prototypes and high-volume component production.

At XY-Global, we specialize in custom 3-axis, 4-axis, and 5-axis milling services, using high-end equipment like Haas and DMG MORI machines for exceptional precision and reliability. Combined with our expert machinists and rigorous quality control (QC) standards, we ensure high component quality and tight tolerances for every project—from rapid prototyping to end-use components.

How Does CNC Milling Work?

CNC Milling is a highly precise subtractive manufacturing process that uses G-code and Computer Numerical Control to guide a rapidly rotating cutting tool to remove material from a stationary workpiece across multiple axes (X, Y, Z), producing complex 3D components with high accuracy.

The core principle of CNC milling involves the rotation of a multi-point cutting tool (such as an end mill) at high speeds, which provides the main cutting action. Unlike CNC turning where the workpiece rotates, here the workpiece is held stationary in a fixture or vise on the machine's table. The CNC controller guides the tool's precise movement along the X, Y, and Z axes to remove material, creating complex geometries and non-symmetrical parts essential for rapid prototyping and manufacturing across metals and plastics.

CNC Milling FAQs

What is the difference between CNC Turning and CNC Milling?

The key difference lies in the motion: CNC Turning involves the material (workpiece) rotating rapidly against the tool, making it highly efficient for circular parts. Conversely, CNC Milling involves the tool (cutter) rotating, which is better suited for producing complex, non-symmetric, prismatic shapes.

What are your guaranteed precision limits? What tolerances can you achieve on 5-Axis projects?

Our standard general tolerance is ±0.1mm, but with our 5-Axis capabilities, we routinely achieve tight tolerances down to ±0.025mm for critical features and materials.

What is the difference between 3-axis, 4-axis, and 5-axis machining?

The number of axes determines the degrees of freedom for the relative motion between the tool and the workpiece: 3-axis is the most basic, suitable for simple, flat parts; 4-axis adds one rotary axis, suitable for cylindrical parts or features around an axis; 5-axis has three linear axes and two rotary axes, allowing processing from more angles, completing complex geometries in a single setup, and achieving higher precision.

How do you ensure consistent quality across large production runs?

We adhere to ISO 9001 standards and employ advanced quality control, including Coordinate Measuring Machine (CMM) inspection and rigorous statistical process control (SPC), guaranteeing uniformity in every batch.

What are the Main Applications of CNC Milling?

CNC Milling span various high-tech industries, including rapid prototyping, the production of complex structural and engine components for aerospace and automotive sectors, the manufacturing of precision medical devices and implants, and the creation of intricate electronics enclosures and tooling/molds due to its ability to consistently produce complex, high-accuracy parts.
