Ultra Line

Modular, newly developed systems of the super-precise ULTRA-series with linear motor drive technology eliminate the division of internal and external processing.

ULTRAs enable freely placeable combinations at first setup with variable layout of all axes. This means maximum adaptability to new production requirements, defined variable creation, or complementary operations at minimum setup times.
 
The ULTRAeco series is offered with a simplified axis concept.

General advantages of the ULTRA series:

  • new machine structure for an optimized machine layout, maximal rebuilding flexibility, easy to service
  • speed and optimized auxilliary process time thanks to highly dynamic linear motor axes for all linear movements
  • economically efficient by a reduction of required space, optimized cycle periods and highest availability
  • all possibilities for efficient automation
