  • Heavy cast-iron machine frame provides a rigid structure with firmly integrated gantry; the setup table provides support across the entire travel distance, including height-adjustable traverse
  • Large setup table is moving on a rigid combination of v-guides and box-ways with ground surfaces for maximum accuracy across the entire work area, independent of table loads and load distribution
  • Both table guides are integrated into a permanent oil circuit; hydrostatic bearings prevent heat build-up and wear, and ensure lasting maximum precision
  • This machine type handles work pieces with weights up to 4409 lb
  • The manually shifted 6-step gear delivers high torque at the headstock
  • Infinitely variable automatic feed on X axis
  • Mechanical axis clamping on all axes
  • Swiveling control panel with long arm allows a wide action radius for the user
  • Automatic central lubrication cutter head (standard)
