Travelling column milling machine

SHW UF6

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.
