Vertical lathes main characteristics:

  • 3 or 4 controlled machine axes,
  • One controlled machine axis for tool magazine, optionally,
  • AC Siemens motors with digital regulators,
  • Precise and robust linear guideways, for high machining accuracy,
  • Plastic/steel slides on X-axis and roller guides on Z-axis
  • With various angular heads, on lathes with turning, drilling and milling unit, five side machining is possible,
  • Automatic tool change and angular heads,
  • High coolant pressure through spindle for turning, drilling and milling tools,
  • Horizontal traverse (W-axis) has a measuring system connected with control unit,
  • Control unit: Siemens 840D sl,
  • Linear, circular, 3D and helical interpolation,
  • Workpieces clamping can be mechanical or hydraulic, with 3, 4 or 8 jaws. Hydraulic clamping can be independent with 2+2 or 4+4 jaws with double cylinder for the easier centring of workpieces,
  • Turning is possible with revolver head with maximum of 8 tools, optionally
  • Lathe tool holders can be with ISO 50 taper or with with ‘HIRTH' coupling, milling and drilling tool holders are with ISO 50 taper,
  • It is possible to implement CAPTO tool holder for both turning and milling tools.

Technological and Technical Possibilities of Vertical Lathes

  • External and internal turning of workpieces,
  • Turning with constant surface speed,
  • Turning of complex shape axis symmetric workpieces,
  • Lathes with C-axis and with turning, drilling and milling unit can be used for:
    • drilling and threading off the vertical axis, and with a help of angular head both operations can be done in any position,
    • milling of various shapes (cylindrical or non cylindrical) in any plane, horizontal, vertical or in arbitrary, with or without angular heads,
    • grinding of complex shapes with grinding heads,
  • Automatic tool changer with tool magazine on the horizontal traverse or foundation (floor),
  • Automatic tool offset correction and workpiece measuring
