CNC Milling


2.png

Looking something like a drill press, a milling machine uses a cutting tool that moves in all three dimensions, removing material to achieve the desired part shape. The cutting tool usually rotates about an axis that is perpendicular to the table that holds the material to be cut. A cutting tool protrudes down from a rotating spindle. A block of material is placed on a moving table below the cutter. While the cutting tool turns, a computer controls the vertical (Z axis) motion of the cutter and the horizontal (X and Y axis) motion of the block of material. The cutter is guided to move through the material, removing portions to create shapes. Additionally, the material can be turned to various orientations in the middle of the process and cutting tools of various shapes can be used.

Milling has several advantages over other manufacturing processes. It is cost effective for short runs. Complex shapes and high dimensional tolerances are possible. Smooth finishes can be achieved. CNC milling can produce almost any 2D or 3D shape provided that the rotating cutting tools can reach the material to be removed. Examples of parts include engine components, mold tooling, complex mechanisms, enclosures, etc.

What Is CNC Milling?

CNC milling is a subtractive manufacturing process where raw material is removed with a variety of precision cutting tools to make a part or product. Advanced software is used to control the equipment according to the specification of your 3D design. Our team of engineers and machinists program the equipment to optimize cutting time, surface finish and final tolerance to meet your specifications. We use CNC milling not only to manufacture parts and prototypes but also to make mold tools, which can be used for our plastic injection molding or pressure die casting services.

Finishing machines treat the surface of your custom part. Finishing can be used for protection, decoration, and other uses. For example you may want to nickel plate a part to protect it from oxidizing or mechanically brush the surface of the part to create a textured look. eMachineShop's intelligent software will also guide you to make sure the finish you specify is compatible with your material.


CNC turning with live tooling combines both lathe and mill capabilities to machine parts with cylindrical features from metal rod stock.


Our CNC turning process produces custom prototypes and end-use production parts in as fast as 1 day. We use a CNC lathe with live tooling so features like axial and radial holes, flats, grooves, and slots can be machined.
