WOHLENBERG PB4-1600 CNC LATHES

Technical Description

This heavy-duty CNC horizontal boring mill features a 55.12-inch chuck and a bar capacity of 16.92 inches, driven by a powerful 160 HP motor capable of a maximum spindle speed of 355 RPM with infinitely variable speed control from 1.8 to 355 RPM. It offers a maximum swing over the bedways of 62.99 inches and a maximum machining length of approximately 10,058 mm (395.7 inches), supported by a robust bed measuring 1,176 inches long and 39.37 inches wide. The machine incorporates the Giddings & Lewis 8000 CNC control system, enabling precise and programmable operations, including a guide carriage and boring slide feed range of 0 to 120 IPM with rapid traverse at 120 IPM, each capable of withstanding up to 22,500 lbs feed pressure. Its main spindle bore diameter is 6.4 inches with front bearing diameter at 11.81 inches, enabling solid boring capacities up to 12.4 inches in diameter and trepanning from 2 to 25 inches. The maximum boring depth along the Z-axis is 396 inches. Workpiece handling is substantial: it supports weights up to 88,000 lbs on one rest, 110,000 lbs on two, and 140,000 lbs on three rests. The machine’s rugged build weighs 180,000 lbs and requires a 460V 3-phase 60Hz power supply. The approximate floor space required is 1260 by 102 inches, making it suitable for large-scale heavy machining applications with high torque capacity up to 39,900 ft-lbs. This machine is engineered for heavy and precise metalworking with extensive reach and endurance.
