CNC Bed Milling Machines: Precision and Rigidity for Heavy Workpieces

Bed milling machines are primarily utilized for machining large and heavy workpieces. The machine's rigid bed absorbs the weight of the workpiece and the machining forces, resulting in minimal positional deviations. The three coordinate axes of movement in a bed milling machine are divided among the table, milling slide, and milling unit, with the table handling longitudinal movement, the milling slide handling transverse movement, and the milling unit managing vertical movement.

Unlike machines with height-adjustable tables, bed milling machines rely on the headstock in the machine column for milling spindle height adjustment. Bed milling machines offer increased static and dynamic rigidity, optimal cutting force absorption, and a spacious working area.

Portal CNC Bed Milling Machines: Accurate and Vibration-Resistant Large Surface Machining

Ideal for machining extensive surfaces, such as face milling large panels, portal milling machines boast a rigid design that ensures high positioning accuracy. Their resistance to vibrations allows the production of workpieces with excellent dimensional accuracy, surface quality, and extreme cutting rates.

The "portal milling machine" name is derived from the portal-like design of the machine tool, where the milling head is guided on a crossbeam between two machine uprights. Depending on the design, the workpiece is clamped on a permanently installed platen or on a machine table that can be moved through the portal.

Boring Mills: High Rigidity and Precision for Massive Milled Parts

Boring mills are versatile machines primarily used for machining large machine parts, typically operating in a horizontal direction. The main headstock, depending on the design, is attached to a fixed or movable column, allowing vertical movement. The spindle moves only in the vertical Z-axis, while the workpiece holder handles all other movement directions. The worktable of a boring mill can move in the X and Y axes via several slides and spindle drives.

Boring mills offer exceptional rigidity, making them popular for machining massive, milled parts requiring a high degree of precision, such as large generator parts or ship engine components.
