Fine positioning in metrology is critical to achieving accurate, repeatable results in precision testing applications where angular alignment and controlled motion directly impact measurement quality.
Unlock Precision & Productivity with the RPI QuadScan Rotary Axis Table
What Is the RPI QuadScan?
The RPI QuadScan is a precision-engineered rotary axis table designed to dramatically expand the capability of Coordinate Measuring Machines (CMMs) for metrology and precision inspection tasks. As part of RPI’s trusted Quadrant range of rotary solutions, QuadScan adds controlled rotational motion to measurement workflows — enabling more flexible, accurate, and efficient inspection of parts in both horizontal and vertical orientations.
Why QuadScan Matters for Modern Metrology
Precision measurement and quality assurance are non-negotiable in industries such as aerospace, automotive, energy, and advanced engineering. The addition of a rotary axis like QuadScan gives manufacturers the ability to:
-
Expand measurement reach – Rotating parts simplifies access to complex geometries and reduces probe repositioning.
-
Boost CMM flexibility – Whether inspecting cylindrical features or symmetrical parts, rotary integration means fewer setups and faster completion times.
-
Improve accuracy & repeatability – QuadScan’s zero-backlash gearing and high-accuracy angular encoder ensure fine positioning for precise metrology tasks.
-
Support both horizontal and vertical applications – Giving you versatility in part orientation and fixturing.
In short, QuadScan enhances traditional CMM inspection by allowing parts to be measured as they rotate, enabling consistent, repeatable access to all key features without costly repositioning or manual handling. This not only increases throughput but also reduces potential for error — critical for meeting stringent quality standards.
Key Performance Highlights
While specific datasheets may provide detailed values, QuadScan is built around these trusted design principles common across the Quadrant product family:
-
Zero backlash gearing — Smooth, reliable rotation supporting high-precision inspection.
-
High-accuracy angular encoder — Ensures precise positioning during scanning or probing tasks.
-
Load range flexibility — Ability to handle parts up to typical metrology loads (e.g., up to ~100 kg depending on table size).
-
Adaptable orientation — Suitable for both horizontal and vertical measurement workflows.
Applications Where QuadScan Excels
Manufacturers and metrology technicians rely on rotary tables like QuadScan to solve real-world inspection challenges:
-
Axial symmetry measurements for shafts, rotors, and gears
-
Scanning surfaces with touch probes or scanning probes
-
Reducing CMM programming complexity with versatile rotational indexing
-
Improving measurement throughput by reducing repositioning errors
These advantages directly support shop floor productivity, ensuring that high-precision inspection can happen consistently at scale.
