Unique dynamic fixture yields a high-precision reading on every ring at production rates
Ring Gage “Floats” to find and measure each individual ring as it passes through the fixture
The application of closed-loop gaging to thrufeed ring grinding has long been difficult because of the high rate of production and the high precision required.Control Gaging has broken both of these barriers at once with its unique "Ring Gage."
As parts leave the grinder they are separated and knocked flat onto a fast-moving conveyor by an ingenious pneumatic device. The gage mechanism rides up onto the part and aligns it square to the gage contacts. The measuring head itself pivots on a flexure to "find" the part diameter.
As the workpiece passes through the gage, the D500 controller's high-speed signal processing determines the precise maximum diameter. Advanced software then combines configurable trend analysis and proven compensation logic for precise control of part size. Parts can be ground more aggressively while maintaining or improving target size accuracy and consistency.
Optional diverter(s) are available to separate out-of-spec workpieces from the parts flow.

The D500 Gage Controller provides a range of software methods for trend-based size control. The advanced IPC option (Intelligent Process Control) significantly outperforms all other compensation techniques, and can control a machine to its best possible operating capability.
