Milling is one of the most wide-spread machining operations in machine-building. In practice, milling is a cutting process involving multi-cutter tool – mill – installed into the spindle of the machine. The main movement of milling machines is rotation of a mill, and main feed travel is a reciprocal movement of a mill and workpiece.
The current market offers a wide variety of milling machines of different configurations, sizes and process capabilities. Milling machines offered by our company are arranged by types according to the established practice and divided into horizontal and vertical types. All machines are controlled with CNC systems.
Horizontal milling equipment is represented by German manufacturer Huller Hille, producing a wide range of horizontal machining centers with different types of tables of different sizes. (from 500x500 mm to 1000x1250 mm) to meet any process challenges.
The main line of activities of Huller Hille is focused on production of horizontal 4 and 5 axe machining centers NBH and NBH 5X. Apart from this, Huller Hille designs flexible manufacturing systems.
The distinctive configuration feature of these machines is horizontal position of the spindle headstock and horizontal position of the working table. Such configuration ensures high rigidity of machine construction, which is especially important for complex roughing and finishing of large and heavy workpieces. Stroke at X and Y axes is effected by movement of the working table, stroke at Z axis is carried out by movement of the spindle headstock.
Also the horizontal milling centers are equipped with automatic pallet changer to enhance productivity and cut down cycle time. There can be two and more pallets (on large machining centers). This allows excluding time for work-piece installation from the overall cycle time, which contributes a lot to time saving as positioning of large and heavy work-pieces can be quite difficult.
Horizontal milling centers normally have a high capacity drive and multi-position tool magazine, which allows a wide range of operations without tool change-over such as milling, drilling, thread cutting and tapping, countersinking and hole-reaming etc.
