Use OGP rotary indexers to automatically rotate parts to bring hidden features for access by selected sensors, for complete part characterisation;
Miniature Servo Rotary (MSR)
The Miniature Servo Rotary is an economical, light duty indexer ideal for measuring parts in multiple views under automatic program control. It is designed for use with any QVI measurement system. The mounting bracket of the MSR allows horizontal or vertical axis applications. With a rotational resolution of 16 seconds of arc, the MSR is ideal for measuring screw machine parts, precision hydraulics and other turned or cylindrical parts. It is also ideal for measuring multiple views of prismatic parts in a single setup.
MicroTheta 4th Axis Rotary (MTR)
The MicroTheta Rotary is a high-accuracy rotary indexer with twin reader heads for ultimate positional resolution with double the load capacity of the MSR. The MTR produces 720,000 counts per revolution of the spindle per reading head, for angular position resolution greater than 2 seconds of arc. With its closed loop feedback system, the MTR makes angular measurements to within ±5 arc seconds. The MTR’s resolution and feedback allow for relational measurements between rotations.
Heavy 4th Axis Duty Rotary (HDR)
The Heavy Duty Rotary is designed for holding heavy parts on a floor model QVI measurement system. With a resolution of 3.6 seconds of arc and an accuracy rating of ±5 arc seconds, the HDR is an excellent choice for larger parts or to support a dual rotary combination, allowing a fifth measurement axis. It can carry loads up to 30 kg-cm. The HDR combines high load capacity with high precision angular positioning in a rotary indexing system designed for demanding industrial applications.
Mount two rotary indexers together with their axes perpendicular to one another to add two more axes of part positioning to select SmartScope® systems.
The part under inspection is attached to the secondary rotary, which is mounted to the primary rotary. The part can be rotated in two different axes to provide a means of bringing features with compound angles into the line of sight of the optical sensor axis and within the reach of available laser sensors or touch probes for measurement.
MeasureMind® 3D MultiSensor fully supports the simultaneous rotation of two rotaries, providing measurement solutions for the most complex parts.
Several combinations of rotaries can be configured, depending on the application and the available measurement envelope of the machine.
High Precision Rotary (HPR)
The High Precision Rotary provides high accuracy air-bearing fourth axis measuring. Its air bearing spindle, DC servo motor, and precision ruled rotary encoder provide the accuracy required to measure angular displacement between features. The HPR may be mounted either horizontally or vertically. Its high speed and rigid body behavior allows 360 degrees of rotation in less than 8 seconds. It is ideal for the most demanding measurements that require the highest precision. It has an accuracy of ±1 arc second.
