Travelling column milling machine

SHW UF6 L

Condition: refurbished (used), Functionality: fully functional, machine/vehicle number: 6255, travel distance Y-axis: 4,100 mm, travel distance Z-axis: 1,600 mm, SHW UF6 #6255 RETROFIT 2025 Travel paths of the base machine: X (machine column horizontal longitudinal): freely selectable (2,000–20,000 mm) Y (headstock slide vertical): 4,100 mm Z (headstock horizontal transverse): 1,600 mm Machine frame X-axis: Inherently rigid construction for dynamic, vibration-damped travel. Three hardened roller compact guideways ensure maximum precision. Machine frame Y-axis: Welded steel construction with two hardened roller compact guideways for high cutting performance with consistent quality. Headstock slide & headstock: Cast GGG 60 construction with hydraulic counterbalance. Two roller compact guideways per assembly. Close arrangement of the guideways in the Y and Z axes prevents tilting. Control: Either Siemens SINUMERIK 840D SL Operate or Heidenhain iTNC530 HSCI. Drive system: Digital feed drives with AC motors (constant torque), feed/rapid traverse: X/Y/Z = 18,000/12,000/15,000 mm/min (infinitely variable). Measuring system: Non-contact direct measuring system with linear scales for maximum accuracy. Safety access: Protection of the rear area is required. A safety switch is provided and installed by SHW. Barriers (fence + door) are provided by the customer, and can be supplied as a complete system optionally by SHW. Access is only permitted when the machine is shut down.
