To eliminate the risk of downtime from failure, our rotary index tables are tested before shipment leaving no room for uncertainty in your production line. The essential criteria to validate our cam-driven rotary index table include accuracy, backlash, stability and mechanical performance.
Rotary index tables are often integrated into high-speed automation line where:
– Downtimes directly affect ROI
– Positioning accuracy greatly impacts product quality.
– Cycle times are measured in fractions of a second
Without testing, your production line is at risk of backlash, misalignment, or instability and may not be apparent until after your system is in production. View our rotary index table testing and inspection report.
The rotary table runout is how true the output is rotating about the rotational axis. This is critical for maintaining the accuracy of each workstation.
Typical tolerance: ≤ 0.03 mm
High-performance systems: ~0.01 mm
Measurement of error of the index in degrees from one station to the next and prevents positioning errors.
Typical spec: ±0.025 mm

Rotary Index Tables can shift slightly even when stopped. Backlash is the amount of unintentional movement when an indexer is in dwell. Motion Index Drives ensures zero backlash Rotary Index Tables.
This is essential for:
Positional accuracy
High-speed automation
Prevent vibration and inconsistency
Measuring the machining of the housing so the fixtures that are 180 degrees apart from each other are on the same plane.
It includes:
Housing parallelism
Surface Flatness
Mounting Alignment
The internal components are sized to accommodate specific loading requirements to match your application needs.
The surface of the cam track is inspected to verify they are free of any defects, ensuring smooth acceleration and deceleration throughout the motion period of the cam. This directly impacts the rotary index table lifespan and prevents premature wear.
If your rotary index table manufacturer cannot provide details to their testing requirements, there may be risk introduced into your production line. To mitigate this, you can ask these questions:
What runout tolerances are verified?
How is backlash measured and eliminated?
What indexing accuracy is guaranteed?
Are dwell stability tests performed?
Although testing is critical in the rotary index table lifespan and providing consistent results, service and support help factors in long-term success. Buyers want to select rotary index table manufacturers that can provide 24/7 support responsiveness, spare parts availability and maintenance.
