THE KAMAN ADVANTAGE

Why use the SMU-9000-6U1 measuring system?

* noncontact. Using eddy current technology, the sensor can measure position without ever touching the target. The result is an extremely reliable system with no moving parts. * high sensitivity. The system's sensitivity of 4 micro-inch/mV allows for precise control of the grinding wheel's position.

* custom design. A microseal treatment protects the sensor face from machining oil and splashing coolant. The SMU-9000-6U1 also incorporates an integral sensor cable, eliminating the need for an electrical sensor-to-cable connection that can be degraded by environmental contaminants.

GOAL

* Controlling the position of a high precision servo grinder.

* Maintaining the position of the grinding wheel to within a few micro-inches to meet the finished part tolerances.

* Making measurements in the presence of environmental contaminants, such as machining oil.

SOLUTION

Kaman's SMU-9000-6U1 measuring system How does the system work? The sensor is mounted above the grinder and monitors the radial position of the rotary drive shaft. A bipolar analog output indicates the position of the grinding wheel relative to the ground part. The signal from the sensor directly controls the position of the grinder through a closed-loop feedback circuit.

Result: Precise grinding of parts for improved component life.
