  • This system and process of the invention entails significant advantages compared to existing solutions.
  • the risk of collision is reduced by means of using two units, one is a combined linear indexer with rotatable indexer, the other is a combined linear indexer with a turret.
  • the present invention extends the basic configuration by a further rotary axis with a large swivel angle on the workpiece side. This allows the production sequence to be implemented with very good accessibility between the workpiece, tool, dressers, measuring systems and the workpiece changing system.
  • the invention simplifies and supports the production sequence in the aspect that fewer and less complex auxiliary axes are required.
  • the additional rotation axis with a large swivel angle opens up a turret or rotary indexing machine functionality. This means that the moving positions of the rotating platform can be oriented towards static positions in its surroundings - the further away from the center of rotation, the more cycle positions are possible.
  • the linear axis below the axis of rotation enables linear movement of all elements on the movable platform.
  • the work piece axis can be oriented parallel to the linear axis - this allows the work piece or dressing tool in the dressing setup, e.g., to be brought into a measuring device or a work piece or tool changing system.
  • the setups 211 described herein enable the finishing of the workpiece inner diameter with radii on the outer edge (e.g., radius grinding) due to the good accessibility.
  • the large swivel angle of the swivel axes, together with the good accessibility, also enables interpolations between multiple movement axes in order to finish the inner radius of the inner diameter.
  • measuring on the machine is supported or greatly simplified.
