Absolute Arm - 7 Axis SE

Features

1. Patented Infinite Rotation in the principle axes allows access to difficult to reach areas, while avoiding damaging the arm against rotational hard stops.
2. Kinematic Probe Joint, the same type used in Hexagon Metrology bridge CMMs, provides repeatable connection of probes, with no need for recalibration. Automatic probe recognition allows you to store hundreds of calibrated probe profiles for instant recall.
3. Redesigned, ergonomic Pistol Grip handle increases operator comfort and productivity.  It is easy to hold, and is used to inspect parts or to interact with the software when in "mouse mode".
4. Patented SpinGrips are infinitely rotating, low-friction "approved" hand hold positions for better user ergonomics. SpinGrips allow the arm to "float" in the operator's hands, reducing stress on the arm thus maximizing accuracy and repeatability while minimizing user fatigue.
5. Absolute Encoders, super high-accuracy rotary encoders, designed specifically for Romer Absolute Arms, improve overall system accuracy while eliminating all complicated "homing" procedures.
6. Aerospace grade Carbon Fiber Tubes provide a lightweight, stiff structure that is thermally stable. Under normal usage the carbon fiber tubes have a lifetime warranty.
7. Low Profile Zero-G Counterbalance balances the arm's weight for easy, operation with effortless control, even above and below the arm's centerline. Better ergonomics means lower operator fatigue and better measuring results.
8. Integrated handle and lifting point under counterbalance allow for easy carrying.
9. Feature Packs plug into the base and provide interchangeable and upgradeable add-on capabilities such as WiFi connection, battery power, interface for laser scanners and more.
10. Universal quick mounting base attaches to a variety of available base and stand options including magnetic bases.
11. Fully integrated scanning solution – no additional cables or controller box
    
    • Automatic laser power control – allows to scan on different surface types with no operator interaction
    • No warm-up time
    • Factory calibrated and certified scanning systems according to B89.4.22 (for Hexagon scanners only)
    • No coating or surface preparation necessary
    • Scanning and probing interchangeable, automated probe recognition
12. Calibrated Length Standard – ROMER provides a NIST traceable calibrated length standard with each arm to allow the operator to easily verify and document system performance for ISO or vendor requirements.

Configurations

The ROMER Absolute Arm Scanner 73 and 75 series offer two different levels of performance and features to suit most inspection requirements.

Technical Specifications

7-Axis ROMER Absolute Arm for External Scanners Probing – 73 series

7-Axis ROMER Absolute Arm for External Scanners Probing – 75 series

All specifications according to B89.4.22.

¹ The Point Repeatability Test is the reference test to determine measurement arm repeatability with ball probe. The cone is in front of the machine. Points are measured from multiple approach directions. The average point and the deviation of each point to the average center are calculated. The result is the maximum range divided by two.

² The Volumetric Accuracy Test is the most representative test for volume measurement accuracy. A gage block with a known and certified length is measured several times throughout the working volume. This gage block is installed in different positions and measured depending on multiple approach directions. The result is the maximum deviation of the measuring distance less the theoretical length.

³ Se designates the ROMER Absolute Arm for external scanner.
