  • Bed, columns and travel tracks form a solid cast-iron frame structure for high rigidity under hard machining conditions and high table loads
  • The gantry construction is fully integrated into the machine frame for maximum rigidity
  • The traverse height is adjustable, ensuring high rigidity even with flat workpieces, since the throat size can be minimized
  • Rigid guides with ground surfaces support the table across the entire travel distance to ensure constant high geometric accuracy
  • Infinitely variable feed on X
  • large setup area with up to 158Ó length and 49Ó width
  • This machine type handles work pieces with weights up to 13228 lb
  • Main spindle gears with 6 steps - for vertical and horizontal operation
  • Including weight balancing system for easy movement and precise positioning of the horizontal spindle head
  • All guideways are protected by telescoping covers or bellows
  • The control panel is mounted on a long arm, giving the user maximum positioning flexibility
  • Standard automatic central lubrication
  • 2-sided machining of the workpiece in vertical and horizontal direction with only one setup
  • Both spindle heads swivel ± 45¡
  • vertical spindle head on height-adjustable traverse can be moved across the entire machining width
  • Easy positioning of the horizontal spindle on the right column guide on Y axis, and via a compact guideway slide 14 in on the Z axis
