Crafting a CNC Rotary Table with Zero-Backlash,Unleashing the Potential of Cam Followers and Cam Indexer


Cam indexers are widely used in the field of machine automation. With the rapid development of Industry 4.0 and automation, there is an increasing demand for cam indexers, of which CNC machining centres are typical representatives.


Different mechanisms of rotary tables

  • DD motor

  • Worm gear

  • Cam indexer

The cam indexer stands out for its exceptional processing efficiency, particularly when operating under light to medium loads. It offers an ideal balance between processing accuracy and longevity.


As a result, it has found widespread application in CNC rotary tables across various industries, including semiconductors, automobiles, and 3C . This versatility and impressive performance have garnered increasing market recognition and demand.

How to achieve high positioning accuracy and repeatability of cam indexers in CNC rotary tables?

Through the perfect engagement of the cam curve and the outer ring of the cam follower, the cam roller mechanism is always in a pre-pressure state, whether in forward or reverse rotation or at a standstill, perfectly eliminating backlash, thus ensuring excellent working accuracy and efficiency, effectively avoiding the loss of internal parts and achieving high positioning accuracy and high repeatability in the machined state.


One of the core components of a cam indexer is the bearing, which is essential for good performance. We recommend cam followers, which are optimized for the actual operating requirements and focus on a number of core indicators： Outer ring/shaft raceway roughness， Outer ring/shaft roundness， Outer ring/shaft concentricity, etc.

When selecting cam follower, the following tips will help your cam indexers run better.


  • Selecting the proper bearing structure - floating/fixed

  • Selecting the appropriate outing grouping to ensure better engagement

  • Selecting the proper mounting method

  • Selecting the proper tolerance - interference fit/transition fit / clearance fit
