The gear blank has always been the quality ceiling of the finished gear. Two pressures—cross-regional grade substitution that ignores hardenability, and the shift toward high-temperature carburizing that demands microalloyed steels—are tightening what it means to properly specify a gear blank.
Solar Atmospheres of Western PA successfully vacuum heat treated two massive H13 extrusion dies at their Hermitage PA facility. Their newest high performing Solar Manufacturing 10-Bar 600 Horsepower high pressure gas quench vacuum furnace was able to fully harden two huge H13 extrusion dies in successive cycles.
Writers are often advised to “write about what you know.” My recent postings on recruitment, employee development, and fitting in was informed by almost fifty years in the gear trade at seven different shops and my consulting firm.
