Instrument Measures Rotary Machine Axis Errors

The API SWIVELCHECK instrument measures and calibrates machine tool rotary axes, tilt tables and pendulum axes. SWIVELCHECK utilizes a servo-driven motor in conjunction with an electronic level and precision rotary encoder to measure multiple parameters in a single set-up.

SWIVELCHECK can operate in automated or manual modes and includes API's Intellicomp software for control, data acquisition and reporting. SWIVELCHECK can also be used in conjunction 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 offers +/- 400° 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 Intellicomp software provides a direct import of measured axis data to machine tool CNC controllers, allowing an update of system parameters for improved precision.

SWIVELCHECK is suitable for use in general machine shops and for users of 5-axis machine tools. As an alternative, API offers contract machine tool calibration services throughout North America using SWIVELCHECK.
