What is CNC Milling?

The Basics of CNC Milling​

CNC mills are automated cutting machines that leverage a rotating spindle-head to eradicate excess material. These machines come in an assortment of sizes and axis configurations. While typically employed to cut harder metals, they are capable of working with workpiece materials spanning from plastic and aluminum to stainless steel and titanium.

How CNC Milling Works​

CNC mills are particularly adept at precision cutting of harder materials. Similar to other CNC machines, a CNC mill is directed by G-Code, which is produced via CAM software. The G-Code commands the machine regarding tool head movement, tool speed, cutting depth, workpiece positioning, and other factors related to speed, feed rate, and coordination. The G-Code's complexity is determined by the number of axes that the milling machine possesses. While mills can also profile cut softer materials, it is not as cost-effective as CNC routers for that purpose. The primary difference between these machines is that a CNC router maintains a stationary workpiece while the router cutting head is guided around it, whereas a CNC mill can move both the tool head and the workpiece.

Finishing Options

At Nexuvo we can generate instant quotes for 10+ surface finishes. We can help you select the right finishes for your applications.

CNC Precision Machining Tolerances

At Nexuvo, we use ISO 2768 standards for CNC machining.

The length of parts that Nexuvo accepts depends on the machining process, with some processes accepting parts up to 48 inches in length. For larger parts, it is recommended to get in touch with Nexuvo's team.

It should be noted that the tolerances indicated are minimums in an optimal scenario and looser tolerances may be necessary based on the process, material selection, or part geometry.

Metrology

At all four of our Nexuvo manufacturing locations, we have a fully equipped metrology department to ensure your part's quality compliance. Experienced engineers in fixture and gauge design from GD&T.

CNC Milling FAQs

Our usual suggestion is to use a minimum wall thickness of 0.5mm for metals and 1mm for plastics. Nevertheless, these values are mainly influenced by the part's size, hence as the part size increases, the recommended minimum wall thickness should also increase. It's worth noting that lower wall thickness values can still be feasible. These recommendations act as limits to mitigate the likelihood of warpage

To ensure precise machining of a part, it is necessary to program CNC machines with offsets for the tool's diameter and length that will be used to cut the part. With accurate knowledge of the tool offsets, a machinist can determine the exact starting point for the machining process.

The CNC milling process involves a rotating tool that carves away excess material from a stationary workpiece.

CNC turning uses a rotating workpiece, typically used to make cylindrical parts.

The most commonly used materials in CNC milling are metals, such as aluminum, brass or steel and plastics such as ABS, acrylic, polycarbonate, and polypropylene.
