Uni-Versal Robotic Eddy Current Test Machine

Uni-Versal Robotic Eddy Current Test Machine

The Uni-Versal™ Test Machine is revolutionizing the way products are quality tested in the automotive industry. It is the first flexible test platform that offers totally robotic testing of metal bearings and spindles utilizing eddy current testing (ECT) for cracks. It is also the first machine of its kind to offer true automatic self-calibration.

The Uni-Versal™ Test Machine was designed to meet the current need for automated, reliable product quality verification of metal bearings and spindles safety-critical automotive parts. The Uni-Versal™ speeds up the verification process with no interruption of flow. It also eliminates the possibility of operator error or misreading of results. True auto-calibration ensures consistently accurate readings.


Central to this machine is the UniWest US-525M multi-channel eddy current testing instrument.

The Uni-Versal™ and has a compact footprint (37" deep × 44" long) and can be installed inline or along side an existing conveyor belt. It can be programmed to handle and test avariety of spindles and bearings.

The operator simply selects the part number, a three-dimensional image of the part appears on the screen, and the Uni-Versal™ automatically resets the gain for that part. One robotic arm then lifts the part from the conveyer and brings it into the test machine where it is placed on a rotating chuck. Another robotic arm manipulates the eddy current probe, while ensuring that it remains precisely the same distance from the part's surface to ensure accuracy. Separate probes robotically test inside and outside diameters for flaws.

The Uni-Versal™ Test Machine segregates rejected parts from verified parts. An optional impact marker can then mark the accepted parts. Verified arts are then returned to the line, so there is no disruption to product flow. Rejected parts are placed onto another conveyor. Parts are divided into zones to identify flaw locations.

The Uni-Versal™ will never be obsolete, as it can be continually reprogrammed to accommodate new part designs. For more information, contact UniWest today.
