Overview: What is CNC Milling?

The Basics Of CNC Mills

CNC mills are automated cutting machines using a rotating spindle-head to cut away unwanted material. CNC milling machines come in a variety of sizes and different axis configurations. They are mainly utilized to cut harder metals but can work with workpiece materials ranging from plastic and aluminum to stainless steel and titanium.

How CNC Milling Works

CNC mills excel at profile cutting harder materials. Like all CNC machines, a CNC mill is controlled with G-Code created through CAM software. The Gg-Code instructs the machine where to move the tool head, how fast to spin the tool, how deep to cut, how to move the workpiece, and other factors relating to speed, feed rate, and coordination. The G-Code complexity depends on how many axes the milling machine has.

Mills can still be used for profile cutting of softer materials, but are not as cost-effective for that use as CNC routers. The main difference between these machines is that with a CNC router the workpiece remains stationary while the router cutting head is directed around the piece, while a CNC mill may move both tool head and workpiece. CNC mills are mainly used in industrial manufacturing, while CNC routing is more common for lower output manufacturing like woodworking.

Why Choose Star Rapid for CNC Machining Services?

Star Rapid’s CNC machining services are second to none. Here are some of the advantages we offer to every client on every project, regardless of size.

✓ Industry-Leading CNC Manufacturing Equipment and Materials

Our imported 5-axis CNC machining centers make turned and milled parts from a wide range of plastic, and metal alloy materials – such as aluminum, brass, nickel, and steel, both mild and stainless steel. We use industry-leading software like Autodesk PowerMill and CGTech Vericut, and we have over 14,000 genuine Gühring cutters in stock.

✓ Comprehensive Raw Material Testing and Verification

Our uncompromising material testing processes are a big reason why our CNC machining services are a cut above. All incoming raw materials are subject to chemical and physical analysis using advanced scientific equipment. No one else offers this level of material quality control, providing you with peace of mind along with Certificates of Compliance upon request. And of course in-process inspection ensures that each part is produced exactly to your design specifications.

✓ A Proven Track Record

We can easily talk about our team’s experience and performance, but one of the best ways to show the superiority of our CNC machining services is to let our work speak for itself. Scroll down to our “See Our Past Projects” section to learn more about some of our thousands of success stories we’ve had with partners. We offer our services for the whole process – from the initial stages of product design, helping with material selection, to the point of manufacturing the first prototypes, to the final production run.

✓ A Full Suite of Finishing Services

Many CNC machined parts require some form of post-finishing before they are ready to be put to use. From bead blasting to polishing, anodizing to plating, laser etching to painting, we offer every surface finish you need to make a great finished part.
