How the Eagle Thread Verifier Works
The ETV thread checking system contains a commercial automatic single- or multi-spindle motor driven test plug which rotates within a tapped hole and monitors the torque. Multi-spindle motors can be arranged to check complete hole patterns simultaneously.
A visual torque monitor provides real-time digital display of the torque reading. The ETV controller compares the torque values to predetermined minimums and maximums, and indicates whether the threaded holes tested are to depth, to the proper size, in the correct location, and square to the part surface.
An RS-232 port is available to connect a monitor and printer to permit you to visually see the gage results or print a report certifying inspection of the tapped holes.
Even at high production rates, the ETV reliably and consistently completes thread inspection test cycles in seconds, without adding time to existing production cycles, and avoiding the errors of manual thread gaging and inspection.
The ETV is a flexible system, which can be designed to fit your manufacturing needs. Mount the ETV thread inspection system on a machine slide in a production environment to probe and verify the proper thread at the point of machining.
Or use the ETV as an independently controlled stand-alone station to check thread depth and size for shipment or assembly.
To thread check a different part, change the mounting bracket for the new hole locations, and replace the thread element in the quick-change chuck.
With .06 TIR radial float, the chuck eliminates the need for precise part positioning. The flexibility of this quick change feature minimizes thread inspection cost per hole.
