The API Swivelcheck instrument measures and calibrates machine-tool rotary axes, tilt tables and pendulum axes. It uses a servodriven motor in conjunction with an electronic level and precision rotary encoder to measure multiple parameters in a single setup.

Swivelcheck can operate in automated or manual modes and includes API’s Intellicomp software for control, data acquisition and reporting, The instrument can also be used in conjunction with the API XD laser interferometer to measure horizontal rotary table position. It 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.

It is easy to set up, offers +/- 400-degree swing and allows tilting axes to be checked at the spindle nose, offering true accuracy to be reported over systems that check at the motor and do not detect ‘lost motion’, the company says. The Intellicomp software provides a direct import of measured axis data to machine tool CNC controllers allowing an update of system parameters for improved precision.
