Rotary indexing tables

Rotary indexing tables are a classic and proven solution in automation technology, especially when it comes to cyclical processes with multiple stations. They are ideal for fast, repeatable processes with a low to medium number of variants.

Key facts about rotary indexing tables in automation are listed below.

Rotary indexing tables can be a good option – but they are not the only one: we analyse, compare and implement the assembly concept that makes the most sense for you, both technically and economically.

The advantages of rotary indexing tables

  • High cycle rates
    Rotary indexing tables allow fast, precise indexing – ideal for series production with short cycle times.
  • High degree of automation
    Production automation using rotary indexing tables reduces manual intervention, lowers labour costs and increases reproducibility.
  • Compact design
    Many processing stations housed in a small space.
  • Good accessibility
    The radial arrangement of the stations facilitates maintenance, installation and retrofitting.

  • Simple structure and control
    There are clearly defined process steps with precisely synchronised movement.

  • High positioning accuracy
    Modern rotary indexing tables are highly precise and repeatable.
  • Robustness and durability
    A mechanically stable design ensures a long service life with regular use.

Restrictions on the use of rotary indexing tables

  • High planning effort for complex processes
    Each work step must be precisely coordinated with the cycle time and placement.
  • Space limitations at stations
    A small amount of space per processing station limits the scope and possible complexity of individual processes.
  • Low flexibility and scalability
    Due to their fixed stations and the defined number of workstations, rotary indexing tables are difficult to adapt to product changes.
  • High impact of localised faults
    If one station fails, the entire system often comes to a standstill (no parallelisation possible).
  • Investment costs for special sizes
    Costs increase significantly for large or particularly heavy-duty rotary indexing tables.

Conclusion

Rotary indexing tables are ideal for fast, stable and space-saving automation solutions for recurring processes. They excel above all in mass production of simple to medium complexity – but are rather unsuitable for highly flexible or highly customised processes.
