Vertical milling machines all work and shape metal in a similar manner. Much unlike a wood or metal lathe, where the workpiece turns at high revolutions and is cut by a stationary tool, a milling machine does the exact opposite.This is where the workpiece is kept stationary and is clamped to the table, while milling tools spin at very high revolutions to make precise cuts.
