FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment, to devices for setting and measurement of angles of orientation of products of instrument making in their manufacturing and control, and may be used in any other area where accurate setting and measurement of angles is necessary. Disclosed is a precision rotary table having a housing, spindle in housing bearings made with possibility of fastening external objects, worm drive spindle. Invention provides for control-measuring system containing angular and radial encoder, serial circuits: sensor optical head - interpolation device - data conversion unit - processing unit, electrically conductive sensor plate - capacity-code converter - input device - processing unit, electromagnetic motor/electromagnetic spindle clamp - appropriate switches corresponding width-pulse generators - processing unit.
EFFECT: technical result is improvement in measurement accuracy, efficiency and applicability.
