We are having an issue with one of our 7-A shapers. We are cutting an internal gear it will work fine for 5-6 pcs and then we will have one part that is .005" larger. Then the next piece will be on size and then the following will be .005" larger again. If disengage the worm on the table and rotate it then we will have another 5 or 6 pcs that will cut on size and then all of the sudden it will go back to cutting every other part oversize. Anyone have any ideas?
