SINGLE PASS SIZING TOOL AND MACHINEINCLUDING WEAR COMPENSATION MEANSAbstractA bore sizing machine of the type having a plurality ofsingle pass abrading tools with a preset single pass cuttingdiameter progressively increasing from one tool to the next isprovided. Each abrading tool includes a wear compensationshaft threadably coupled at one end to an axially slidabletapered arbor inside the tool body and driven at the other endoutside the tool body by a stepping motor or other drive meansto slide the arbor relative to abrading means carried on thearbor or tool body to return a worn tool diameter to theoriginal preset single pass cutting diameter, preferably inresponse to a signal from wear sensing and signaling means.
