This is the timely and relevant sequel to our Nov/Dec 2018 Addendum article, "Safety Guaranteed." In the original article will looked at some incredible gear applications
from the safety of our desktop computers and smartphones. Who knew we would be spending most of 2020 doing the same exact thing?
The higher load carrying capacities, compact dimensions and longer life of hardened gears is an accepted fact in industry today. However, the costs involved in case hardening and subsequent finishing operations to achieve these advantages are considerable. For example, in order to achieve desired running properties on larger gears, it has been necessary to grind the tooth flanks. This costly operation can now be replaced, in many cases, by a new Hard Cutting (HC)
process which permits the cutting of hardened gears while maintaining extremely low tooling costs.
