CNC Milling Capabilities
CNC milling is a machining process that uses rotating cutting tools to remove material from a stationary workpiece. The cutting tool moves along multiple axes (typically 3, 4, or 5) to create complex three-dimensional shapes. CNC mills can perform face milling, peripheral milling, slot cutting, pocket milling, drilling, boring, reaming, and contouring. Modern CNC milling centers feature automatic tool changers with magazines holding 20-120+ tools, enabling complex parts to be completed in a single setup. This versatility makes CNC milling the backbone of precision manufacturing.

CNC Milling in Aurora — FAQ
How many CNC Milling providers are in Aurora, IL?
The Chicago-Naperville-Elgin metropolitan area has approximately 500 manufacturing establishments, many of which offer cnc milling services. The area employs about 12,000 manufacturing workers, ensuring a skilled workforce for your project.
What is CNC milling best used for?
CNC milling excels at creating parts with flat surfaces, complex pockets, slots, holes, and 3D contoured surfaces. Common applications include engine blocks, mold tooling, brackets, housings, and precision components for aerospace and medical devices.
What is the difference between 3-axis and 5-axis milling?
3-axis milling moves the cutting tool in X, Y, and Z directions, suitable for most flat and moderately complex parts. 5-axis milling adds two rotational axes, allowing the tool to approach the workpiece from virtually any direction, enabling complex contours, undercuts, and single-setup machining of multi-sided parts.
How thick of material can a CNC mill cut?
CNC mills can cut through materials of virtually any thickness, limited only by the machine's travel range. Typical vertical mills handle workpieces up to 20-30 inches in height. Large gantry mills can machine parts several feet thick.
What size parts can be CNC milled?
CNC milling machines range from benchtop units for small parts (a few inches) to large gantry mills that can machine parts 20+ feet long. Most job shops handle parts from a fraction of an inch up to several feet in any dimension.
