Dynamic rigidity and thermal stability for the highest precision of your turned parts.

  • 65 mm spindle clearance
  • 160 mm chuck diameter
  • 6,000 rpm max. speed

Machine highlights

Your benefits

  • Simultaneous machining with up to 3 tools

  • Easy change-over and handling by very good accessibility to the work area

  • Process reliability through vertical and clearly structured work area with large axis travels and generously sized tooling circles

  • Economic power density due to small erecting dimensions

  • Dual function of the lower X/Z slide:
    Tool turret and swiveling counter spindle for rear end machining


TNK series in focus


The machine design

The main spindle

  • Highly dynamic motor spindle in synchronous design

  • Fast acting C-axis positioning for short cycle times

  • Liquid cooling supports the thermal stability of the machine

  • High spindle performance allows large cutting volume

The back working attachment

  • 8 tool stations

  • 5 of which are live tool stations (12,000 rpm and 6.7 kW)

  • Long travel distances of the counter spindle allow a large tool pool

Upper tool carrier

  • 10 tool stations

  • Powerful tool drive on all stations

  • Long axis travels

  • Turret indexing designed as NC rotary axis (without mechanical interlock) allows any angle positioning and chip-to-chip times of 0.4┬ás (station to station)

  • Simple multiple tooling of tool stations

Counter spindle with lower tool carrier

  • Powerful counter spindle with large travel distances in the X- and Z-axes

  • Integrated tool turret with 9 stations

  • Fast C-axis positioning


Dual Drive (option)

The drive system in which the next tool is accelerated or decelerated during main time. Moderate acceleration and gentle deceleration ensure a long service life of the live tool holders. The Dual Drive system allows a tool change from live tool 1 to tool 2 in just 0.4 s chip-to-chip time
