Our advanced turning centers and experienced team excel in producing cylindrical and complex components with exceptional precision and reliability, from prototypes to full-scale production. Equipped with multi-axis capabilities, live tooling, and sub-spindles, our CNC turning centers efficiently machine intricate features while maintaining tight tolerances across a diverse range of part geometries.

The 3-axis CNC mill is the most commonly used type of milling machine, offering full control over the X, Y, and Z axes. Its versatility makes it ideal for handling a broad range of machining tasks.

This type of router enables the machine to rotate along a vertical axis, allowing the workpiece to move for seamless and continuous machining.

5-axis CNC routers feature three traditional axes plus two additional rotary axes, enabling them to machine five sides of a workpiece in a single setup without requiring removal or resetting. The workpiece rotates, while the spindle head moves around it for precise, continuous machining. These machines are larger and more costly but offer unparalleled versatility and efficiency for complex tasks.

What is CNC Milling?

CNC mills are automated cutting machines equipped with a rotating spindle head designed to remove unwanted material with precision. Available in various sizes and axis configurations, these machines are versatile and capable of machining a wide range of materials, from plastics and aluminum to stainless steel and titanium. While commonly used for harder metals, CNC milling is adaptable to diverse manufacturing needs.

How CNC Milling Works

CNC milling relies on G-Code, a set of instructions generated by CAM software, to control the machine’s movements and operations. The G-Code dictates:

Tool head positioning and movement.
Spindle speed and cutting depth.
Feed rates and workpiece adjustments.

The complexity of G-Code corresponds to the number of axes the milling machine operates, with advanced multi-axis mills capable of creating intricate geometries.

CNC Milling vs. CNC Routing

While CNC mills are ideal for profile cutting harder materials, CNC routers are better suited for softer materials like wood and plastics. Key differences include:

Workpiece Movement: CNC routers keep the workpiece stationary, moving the cutting head around it. CNC mills move both the tool head and, in some cases, the workpiece itself.
Applications: CNC milling is primarily used for industrial-scale manufacturing, while CNC routers are favored for smaller-scale production, such as woodworking and sign-making.

CNC mills excel in precision, making them the go-to solution for industrial applications where accuracy and material versatility are paramount.
