Controller and Software

  • Flexium+ has new and enhanced features, new panels, a new HMI, an enhanced servo bus, enhanced drives and simplified connectivity.
  • With NUMROTOplus®, a wide range of tools can be manufactured and resharpened, Each tool detail can be adjusted to suit individual needs, an exceptional variety of programs with a built-in database for tools, technology and grinding wheel packages, Auxiliary pictures for all parameter settings, displaying true to scale tool dimensions.
  • The 2D simulation is an integral part of NUMROTOplus®,
    all grinding operations can be simulated on the PC using the 2D simulation, With the integration in the NUMROTO software of 3D tool simulation with grinding process animation and collision monitoring with 3D machine simulation.
  • NUMROTO Draw (opt. )
    After entering all geometry parameters a dimensioned projection drawing can be created automatically, which are taken as true-to-scale color graphic image or DXF drawing from the 3D simulation.
