What is CNC Milling?
CNC Milling is an automated machining process used to manufacture 2D and 3D parts. A CNC Mill removes material from a block or sheet using pre-selected cutting tools.
Commonly, the workpiece sits on a moving table below the cutting tool which protrudes down from a rotating spindle. A computer controls both the vertical motion of the cutter and the horizontal motion of the material. The cutter slices through the material, removing portions to create shapes.
The ideal cutting tools for each part varies depending on the design specifications. More frequently used types of milling tools include drills, taps and end mills.
If you need custom milled parts, design and order them using the free eMachineShop CAD or get a fast quote for your existing design.
- Can produce parts of almost any shape
- Cost-effective for prototyping and short runs
- High dimensional tolerances are possible
- Smooth finishes can be achieved
- Avoid flimsy shapes
- Use shapes that will hold well during machining, like straight edges
- Milling creates a visible cut pattern on the surface of the material
- Avoid deep pockets and ensure corners are rounded
Plain End Mill
Creates walls with straight 90 degree edges and sharp corners at the bottom of recesses.
Chamfer End Mill
Creates 45 degree bevels on the top edge of a wall or recess.
Ball End Mill
Creates rounded edges at the bottom edge of a recess.
Rounding End Mill
Creates rounded edges at the top edge of a wall or recess.
Typically used to cut the pins and tails of dovetail joints.
