Eddy Current Systems


Starting with the Uni-Versal Test Machine, a flexible platform for testing many different machined and forged parts, SDM produces custom machines for production-testing parts for cracks, flaws, and heat treat characteristics. Custom integrated material handling includes robotics and servo controlled manipulators.
Uni-Versal Test Machine

Uni-Versal Test Machine

This is a flexible test machine for inspecting parts for cracks using eddy current. A robot is used to position the part and a second robot moves the eddy current probe over the surface to be inspected. Since all motions are programmable, many different parts can be inspected with minimal changeover required.

Spindle Inspection Machine

Spindle Inspection Machine

Using a robot to pick and return accepted parts to the conveyor, this machine tests automotive spindles for cracks on their outside surfaces using eddy currents. Two servo-controlled eddy current probes scan the surfaces of the part. Rejected parts are placed on a reject conveyor.

Side Line Inspection System

Side Line Inspection Machine

This system uses a robot to pick up rings from two inlet tracks and place them in a test fixture where the OD and ID of the rings are eddy current inspected for cracks. Parts are segregated with accepted parts put back on the conveyor they arrived on. Two different part types are processed by the machine interchangeably.

Slug Inspection Machine

Slug Inspection Machine

This machine inspects slugs cut from tubing for cracks on their OD and ID and then checks them dimensionally for ID, OD, wall thickness, and squareness. A V-conveyor is hand loaded and good parts are segregated from bad on exit rails. The machine changes to test a variety of OD and wall thicknesses through the programmable servo controlled motions.

Ring Inspection Machine

Ring Inspection Machine

This machine inspects machined rings for cracks on their OD and ID. A V-conveyor is hand loaded and good parts are segregated from bad on exit rails. The machine changes to test a variety of OD and wall thicknesses through the programmable servo-controlled motions.

Roller Inspection Machine

Roller Inspection Machine

This machine inspects hardened rollers for heat treat characteristics utilizing eddy current technology. Parts are processed as they leave a centerless grinder, the part passed through an encircling coil and reject parts are removed. The processing speed is over 6 parts per second.

CV Cage Inspection Machine

CV Cage Inspection Machine

This machine inspects the ID and OD of a spherical CV joint cage. The cage is clamped and rotated as the eddy current probes are programmed to pass over the surfaces. Different part geometries may be processed. The accepted parts leave the machine, and rejected ID and OD parts are segregated.
