There are three main types of large machining centres; gantry type, double-column type, and moving column type:
Gantry Type Machining Centres
Gantry-type machines typically have a single chassis with a fixed table/workpiece, and the spindle moves in all directions along the X, Y & Z axis.
Double-Column Machining Centres
Double-column type machining centres (also referred to as ‘bridge’ or ‘portal’ type) however have a table that can move along the X axis (which is normally the longest axis).
Double-column machines, known for their rigidity, are also available with a vertical moving cross beam;
Moving Beam Type
As the name suggests, moving beam type double-column machines have a crossbeam than can be moved up and down (W axis). This is an extension to the spindle moving up and down on the Z axis, and ensures maximum rigidity for any sized part.
Moving Column Type
Like gantry type machines, moving column machining centres have a fixed table or workpiece. Unlike the gantry type though, moving column machines are not a one-piece construction, instead the table is fixed to the floor. The spindle is mounted on a separate bridge beam which spans the table/workpiece. The bridge is then mounted on both sides of the table to a running guideway system.
Oftentimes, moving column machines also have a box-in-box style bridge construction due to the rigidity requirements of heavy workpieces.
