CNC Milling

CNC milling is one of the most popular CNC machining techniques employed for building prototypes as well as high-volume parts across industries. It is a subtractive process, wherein the metal or plastic block is milled to the desired shape. Princeton Industrial’s CNC milling services are well-known and reliable, we can create parts with complex geometries for prototyping or low to mid-volume production.

At Princeton, we can support 3-, 4-, and 5-axis milling, which enables us to create complex geometries easily. Our CNC machining centers provide accuracy for those parts that cannot be turned. These machines can perform many labor intense operations with extreme accuracy and consistency holding tolerances as close as .0002″. Our multi-axis CNC machining capabilities coupled with our experience allow us to assure on-demand lead times and competitive pricing. We can provide instant quotes and to receive it all you have to do is upload your CAD design and receive DFM feedback. Please contact us today to get instant quote.

An Overview of CNC Milling

In this process, the workpiece to be milled is held in a fixture or vice, which is usually mounted on a working table. The CNC milling machine is guided by a G-code that controls the action of milling tools. We use multi-axis CNC milling machines where the spindle, as well as worktable, can move independently on different axes without affecting each other’s work. This assures high accuracy and versatility. The metal parts, thus, created can be surface finished using different options like painting, chromate plating, and anodizing.
