A milling machine is a machine tool that removes metal as the work is fed against a rotating multipoint cutter. The milling cutter rotates at high speed and it removes metal at a very fast rate with the help of multiple cutting edges. One or more number of cutters can be mounted simultaneously on the arbor of the milling machine.

How It Works. Pavement milling is achieved using a heavy-duty piece of construction equipment known as a milling machine, or a cold planer. Milling machines utilize a large, rotating drum that removes and grinds the surface of the asphalt. Scrolls of tool holders cover the exterior of the drum and hold the carbide cutters that actually cut the ...

For a CNC milling machine (aka CNC machining center), the work piece is fixed or mounted in position using a vice or fixture while the cutting tool is manoeuvred on top of or around the piece. Material is then gradually removed using cutting tools or drills which rotate at high speed with varying feed rates along two or more axes.

Work on a milling machine is most often held in a vise clamped onto the bed. To make features aligned with the edges of the stock, it's neccessary to align the vise with the feed axes of the mill. To do this, mount the vise on the bed and secure it with T-bolts, but only lightly so as to permit adjustment of the orientation of the vise.
