Precision CNC Milling Services

The Foundation of Modern Manufacturing

CNC (Computer Numerical Control) milling is a subtractive manufacturing process that uses computer-controlled rotating cutters to precisely remove material from a block of raw material (the workpiece). A 3D CAD model is converted into a set of machine instructions (G-code), which then directs the cutting tool along multiple axes to create the final part geometry.

This process is incredibly versatile and is used to manufacture parts for nearly every industry, from aerospace and medical to consumer electronics. Its ability to hold tight tolerances and create complex features makes it indispensable for both prototyping and full-scale production.

Multi-Axis Milling for Unlimited Complexity

Our investment in advanced machinery allows us to tackle projects of any complexity, reducing setup times and increasing accuracy.

3-Axis and 4-Axis Milling

3-axis milling is the most common form, where the cutting tool moves along the X, Y, and Z axes. It is highly effective for parts with features on a single plane. By adding a 4th axis (A-axis), we can rotate the workpiece, allowing for machining on multiple sides of a part in a single setup. This is ideal for creating features around a cylindrical part.

Ideal For: Housings, plates, brackets, and parts with features on up to 4 sides.

5-Axis Milling

5-axis milling adds a second rotational axis (B-axis) to the machine's movement. This enables the cutting tool to approach the workpiece from a full 360 degrees in a single clamping. It is the definitive solution for parts with highly complex, organic shapes and deep cavities with contoured surfaces, eliminating the need for multiple setups and dramatically improving accuracy.

Ideal For: Medical implants, aerospace components, turbine blades, and complex molds.

CNC Milling FAQ

What information is needed for a quote?

The most important item is a 3D CAD file (STEP is preferred). In addition, a 2D drawing (PDF) is highly recommended if you have specific tolerances, threads, or finishing requirements that need to be called out.

Can you mill transparent plastics like acrylic?

Yes, we frequently mill transparent plastics like acrylic (PMMA) and polycarbonate (PC). After milling, these parts will have a translucent, matte finish. For optical clarity, they require secondary polishing processes, which we also provide.

How does part complexity affect the cost of milling?

Cost is primarily driven by machine time. More complex parts, especially those requiring 5-axis machining, deep pockets, or very thin walls, will take longer to program and machine, which increases the cost. Similarly, parts requiring multiple setups on a 3-axis machine will be more expensive than those that can be completed in one or two setups.
