SwivelCheck Measures and Calibrates Rotational Axes

Aug. 14, 2019
API's calibration device calibrates swivel axes and tilt tables on machine tool centers and evaluates vertical rotary axes and table performance.

Swivelcheck is a one-of-a-kind instrument used to measure rotary axes and tables in the CNC Calibration process. This instrument calibrates swivel axes and tilt tables on machine tool centers; evaluates vertical rotary axes and table performance; and measures horizontal tables and axes when used with API’s XD Laser.


The Swivelcheck uses a servo-driven motor in conjunction with an electronic level and a precision rotary encoder. Once set up, the system is capable of running in automated or manual modes. The Swivelcheck has been designed with ease of use, efficiency, and accuracy in mind and is the rotary axis instrument of choice for professional machinists.
