Modular machine tools

Innovative machine concept

  • Machining of the stationary workpiece by rotating tools
  • High manufacturing quality with simultaneous operations
  • Customised equipment due to modular design

Tool carrying module

... is assembled from optionally configurable two, three, four or six universal tool slides.

The tool carrying module can be equipped with tool carrying modules tailored to the actual machining job to enable various operations by a single unit system in one setup.

The changeable tools can be replaced by means of quick-action systems requiring minimum time only.

Coolant is directly fed to the machining area through the tools themselves.

Last but not least the versatile equipment of the tool carrying module providing for multiple functionality.

Longitudinal external machining
  • Peeling
  • de-scaling
  • Continuous-path turning

Peeling, de-scaling
  • Facing, chamfering, deburring
  • Copy milling
  • Thread cutting according to API, GOST, VAM, DIN, ISO etc.
  • Special connections including gaskets
  • Cutting off

The clamping module

.... is basing on a vibration-damping machine bed and clamping systems traversing along the Z-axis.

According to the work geometry and machining specification adapted centring clamping systems can be applied. In addition to enveloping wedge-hook power chucks internal and prism-shaped clamping systems can be used as well.

The drive module

... consists of a patented hollow-shaft gearbox and attached CNC-controlled drive motor assemblies

The hollow-shaft gearbox drives the tool carrier module and tool slide. Further drive assemblies control the Z-axis and clamping module.

The hollow-shaft gearbox enables traversing maximum six tool slides both independently of each other and decoupled from the rotation of the tool carrying module.

Advantages you benefit from our machine concept

  • Wear minimisation by work clamping tools
  • Reduced vibrations of machine and workpiece
  • Small floor area required due to compact machine size
  • Complete machining of intricate rotationally-symmetric machining jobs in a single unit system
  • Up to six tool slides CNC-controlled independently from each other
  • Multi-step machining in a single setup
    • Minimisation of basic machining and non-productive times
    • Increased metal-removal rate
    • Reduced piece costs
