UNION CHEMNITZ PR II 200 HORIZONTAL BORING MILL

The UNION CHEMNITZ PR II 200 is a high-performance Horizontal Boring Mill featuring a floor plate design with a RAM and traveling column configuration, suitable for machining large, complex workpieces. Key specifications include a Spindle Size of 200 mm (7.87 inches), complemented by significant traverse capabilities: an X-Axis (Column transverse travel) of 4,000 mm (157.5 inches) and a Y-Axis (Head vertical travel) of 2,500 mm (98.43 inches). The machine is powered by a robust Spindle Drive Power ranging approximately from 30 to 52 kW, achieving up to 4,000 RPM, and controlled via a CNC system. The design includes features like vibration damping, strongly ribbed cast iron beds, and water-cooled AC motors, enabling sophisticated machining operations such as horizontal boring and milling, with the potential for 5-side machining. The Z-Axis (Ram longitudinal travel) extends up to 2,000 mm, while the Boring Spindle Axial Traverse (W) reaches up to 1,000 mm. This mill is part of the PR-series, generally designed for very large workpieces potentially up to 40 meters in length and weighing up to 250 tons, with available options like automatic tool, pallet, and milling head changers.
