CNC milling is a sophisticated and efficient subtractive manufacturing technique, controlled by advanced computer numerical control (CNC) systems. This process minimizes the need for manual intervention by automating tasks based on CAD files uploaded to the CNC machine. In CNC milling, rotary cutting tools methodically remove material, shaping it to achieve the specific design of the final part.

The versatility and complexity of the parts produced by CNC milling are largely dependent on the number of axes the machine possesses. Machines with more axes can create more intricate designs, enhancing the precision and detail of the CNC milled parts. While CNC milling is often synonymous with CNC machining, it’s important to note that machining encompasses both CNC milling and CNC turning.

Modern milling centers have evolved to integrate both milling and turning processes, offering comprehensive machining solutions. This development enhances the capabilities of CNC milling, making it a crucial component in various industries, including automotive, aerospace, and general engineering, for producing complex and precision components.

The CNC milling process begins with the creation of a virtual model of the final product using CAD (Computer-Aided Design) software. This design is then transformed into a machine-readable format using CAM (Computer-Aided Manufacturing) software, which converts the design into G-code. This code serves as precise instructions for the CNC milling machine, guiding every movement to fabricate precision parts with accuracy.

While the CNC machine predominantly operates automatically, certain aspects of the process still require manual intervention by a machine operator. Tasks like securing the workpiece to the worktable and attaching the milling tools to the spindle are essential to prepare the machine for operation.

Modern milling centers have further enhanced the process with live tooling capabilities, significantly reducing production times. This advancement allows for various operations to be performed seamlessly without the need for tool changes, streamlining the manufacturing process.

CNV Engineering’s comprehensive network of manufacturing partners provides access to an extensive range of CNC milling capabilities, ensuring we meet your high-precision machining needs in a cost-effective manner.

Our network includes various types of CNC mills, each suitable for different levels of complexity and precision in part manufacturing. The choice of the mill depends on the complexity of the part and the economic feasibility of using advanced machines for simpler tasks.

3-axis Mill: In a 3-axis mill, the rotating tool moves in three directions: X, Y, and Z axes. The tool remains fixed either in a vertical or horizontal position, based on the specific machine. This type is commonly used for relatively simpler parts.

4-axis Mill: Adding to the capabilities of a 3-axis mill, the 4-axis mill includes a rotating table around the X-axis. This feature allows machining the sides of a workpiece without needing to reposition it. Though more versatile than 3-axis mills, 4-axis mills are less common.

5-axis Mill: A 5-axis mill extends the functionality of the 4-axis mill, enabling the workpiece to also rotate around the Y-axis. These mills are adept at producing highly complex parts in a single setup, reducing the need for additional setups.

6-axis Mill: Although not as common due to their cost, 6-axis mills offer exceptional speed and versatility. They feature stationary worktables with the cutting head moving in the X, Y, and Z directions and rotating around all three axes. These mills are ideal for projects where speed and complex geometries are paramount.
