Milling can follow the layout of the form and scope to distinguish it together to understand the following classification:
 A milling machine: There is universal, horizontal and vertical, mainly used for machining small parts, the most widely used.
 2. milling machine: including gantry milling and boring machine, gantry milling bed and double-column milling machines are used for machining of large parts.

3. Single column milling machines and milling arm: horizontal milling along the former rail mobile column, table for longitudinal feed; the latter's vertical milling head can move along the guide rails cantilever, the cantilever can also adjust the height of the column along the rail. Both for machining large parts.
 The table does not lift milling machine: a rectangular work desktop desktop work round two, is between lifting a medium size milling machine and milling machine milling between. Its vertical movement by milling in the column on the lift to complete.
 5. Instrument milling: a small milling machine for processing instruments and other small parts
6. milling tools: for mold and tool making, with a vertical milling head, universal angle table and plugs and other accessories, but also for drilling, boring and slotting processing.
 7. Other Milling: If keyway milling, cam milling, crankshaft milling, roll milling and square ingot milling journal, is dedicated milling machine for machining a workpiece corresponding manufactured. Press control, milling is divided into profiling machine (see copying machine), program control milling machines and digital control milling machine (see digital control machine)
