Machine concept

The KT series is designed for economical CNC machining of large components. Flexible Milling heads / heads enable precise and versatile machining of different workpiece geometries.

Typical applications

  • Mechanical engineering
  • Toolmaking
  • Power plant construction
  • Steel construction
  • Machining of large parts
  • Robust cast construction
  • Highly dynamic feed drives

Brief description

The CNC Bed type milling machines / machines of the KT series enable the machining of large, complex workpieces thanks to the large cross travels of up to 1,600 mm and table widths of up to 1,400 mm. Can be extended with attached or integrated rotary tables or Carousel turning tables with interference circle diameters of up to 2,300 mm.

Highlights of the machine

All highlights can be found on the machine card.

Linear guideway

  • Backlash-free Linear roller guide for maximum accuracy
  • Low friction for high dynamics in 2.5/3-D machining
  • High rigidity due to high number and larger roller recirculation units
  • Low maintenance and wear costs

Rotation

  • Automatic Stepless / stepless positioning
  • Simultaneous machining 100% ED (S1)
  • High swivel speed thanks to torque drive (360°/s)
  • High speeds 8,000-15,000 rpm 100% ED (S1)
  • Quick tool change

Multitask

  • Multifunctional machine through the use of Carousel turning table(s)
  • Turning on the machine with Capto C5/C6 tool holder
  • Automatic turning tool change possible
  • Grinding on the machine with grinding spindle

Accuracy

  • More stable casting structure of the entire machine calculated by FEM
  • Maximum precision in the Milling slides axis thanks to pretensioning of the INA guideways
  • Ground contact surface for all guideways; measuring systems etc.
