Static type
Test rods that focus on high quality and accuracy, periodic check of runout values help to pre-empt any potential problems.
- The high-precision test rod is developed by BIG’s high-precision machining technology.
- Periodic assessment of accuracy Helps reduce the amount of waste work
- There are many to choose from, supporting each interface standard.


Dynamic type
- Evaluate the accuracy of the machine spindle’s dynamic runout. By measuring the run-out value while rotating at the speed in actual use.
- Knowing how the dynamic accuracy of a machine tool spindle is affected by centrifugal forces, vibration, and heat helps determine the optimum cutting parameters and conditions in actual use.
