Description

The TFN is a high accuracy gage fixture consisting of an Tupper carbide shoe assembly, two side guides and a lower carbide anvil assembly. As parts stream through the fixture, a ruggedized Probe converts the movement of the shoe assembly into an electronic signal that is processed by a PD6n statistical controller.

The TFN gage fixture is extremely robust and can either be mounted to the exit workrest of the grinder or conveyor mounted if backpressure is a concern. The TFN gage fixture “snaps” into the base assembly to provide easy access to the gage for maintenance.

The TFN is your best choice for automatic size control of rollers, pins, needles, plungers, and small spools.

The TFN is used with the PC-based, PD6n statistical controller. The PD6n samples the measured data, assembles it into subgroups and generates an average plot which is displayed in an X-bar & R format. At a glance the operator can see part size distribution and trend. This statistically based closed loop size control system automatically compensates for wheel wear and other grinding variations.

Intelligent Process Control algorithms monitor normal part-to-part variation and removes them from the compensation analysis. This allows the statistical controller to maintain the tightest possible compensation settings even as grinding conditions are changing.
