API’s SWIVELCHECK measures the rotary and pendulum axes and tilt tables of machine tools and can also calibrate their errors. SwivelCheck combines a servo-driven motor with electronic level and precision rotary encoder to measure numerous parameters from one measurement position.
SwivelCheck operates in automated or manual mode and includes API’s Intellicomp software for control, data acquisition and reporting. SwivelCheck can also pair with the API XD Laser interferometer to measure horizontal rotary table position. SwivelCheck can be mounted off-center of the rotating axis to measure the swivel axis of trunnions without need for disassembly of critical machine tool components.
SwivelCheck is easy to set-up, offers +/- 400 degree swing, and allows tilting axes to be checked at the spindle nose. This allows true accuracy to be reported over systems that check at the motor and do not detect ‘lost motion’. The Intellicomp software directly imports measured axis data to machine-tool CNC controllers, allowing an update of system parameters for improved precision.
SwivelCheck is an invaluable tool for validating machine tool rotary axis performance in general machine shops and users of sophisticated 5 axis machine tools. For those who don’t need Machine Tool Calibration (MTC) products full-time, API Services offers contract machine-tool calibration services throughout North America using SwivelCheck, XD Laser, and others.
