About this machine
The Union PU 130 is a used CNC boring mill — sometimes referred to as a horizontal boring machine — offered here from Belgium. Boring mills of this type are heavy-duty machining centres designed for precision boring, milling, drilling, and threading of large, complex workpieces, and are widely used in industries such as energy, aerospace, heavy engineering, and mould and die manufacture. Union is a well-established German machine tool builder with a long history of producing high-specification boring and milling machines for demanding industrial applications.
This is a floor-type configuration equipped with a facing and boring head and fitted with five controlled axes: X, Y, Z, W, and U. The U-axis is a CNC-controlled cross slide with a travel of 150 mm, integrated firmly into the spindle system. This plan support enables the machining of large external and internal contours, ring grooves, cones, and threads in automatic mode, and in combination with the remaining axes it extends the machine's capability across a wide range of contour-machining operations. Crucially, the drilling spindle remains fully usable across its entire speed range independently of the cross slide.
The milling spindle has a bore diameter of 130 mm and is fitted with an ISO 50 taper. Spindle speed ranges from 5 to 3,000 rpm, and spindle power is rated at 51 kW. Cooling through the spindle is provided at 20 bar. The W-axis (spindle traverse) offers 750 mm of travel, while the Y-axis (cross traverse between table and column) provides 800 mm.
The machine is equipped with four T-slot tables, each measuring 5,000 × 1,500 × 300 mm, accommodating large and heavy workpieces. A chip conveyor is included for efficient swarf management. Control is handled by a Siemens Sinumerik 840D CNC system, a high-capability controller widely regarded in the industry for its suitability on complex multi-axis machining centres.
