OERLIKON DM 4 S MANUAL LATHES

Technical Description

The Oerlikon DM4S is a heavy-duty manual turning lathe designed for large-scale precision machining operations. This machine features a maximum swing over the bed of 1140 mm (44.88 inches), enabling the machining of substantial workpieces with considerable diameter requirements. The lathe accommodates a maximum swing over the cross slide of 810 mm and provides an enhanced swing capacity in the gap of 1350 mm, allowing for increased flexibility in workpiece configuration and tool positioning. With a center distance (length between centers) of 3200 mm, the DM4S offers substantial turning length for extended workpieces. The spindle bore measures 62 mm, providing adequate clearance for shaft work and accommodating various tool and accessory configurations. Operating at a spindle speed of 660 rpm, this lathe is optimized for heavy-duty turning operations requiring controlled cutting speeds and superior torque delivery. The machine's robust construction and specifications classify it within the category of heavy-duty lathes exceeding 3000 mm in length between centers, making it suitable for industrial production environments. The DM4S delivers reliable performance for turning, facing, and boring operations on large ferrous and non-ferrous workpieces. Its manual operation provides operators with direct control and tactile feedback, essential for precision work and specialized machining tasks. The lathe's substantial bed height and rigid construction ensure minimal deflection during cutting, supporting consistent dimensional accuracy and superior surface finish on demanding applications.
