The year was 1999, and the company had just enjoyed the best year in its relatively short history. Founded just three years earlier, in 1996, Mike Magee recalls being amazed by how many orders for ...

At Kleiss we refer to polymer gear making as a “subtle science and exacting art,” and 20 years of experience has shown that a gear is a very special shape that is not well understood fr...

Gear whine is an annoyance for automotive consumers. For all practical purposes it cannot be eliminated, but only minimized. Gear whine stems from transmission error that is a result of manufacturi...

If a mechanical or electromechanical component has to function for extended periods in an extreme environment, a perfluoropolyether (PFPE) lubricant just may be the key to long life and smooth perf...

The process of rotary broaching has been around for a long time, but there are still many machinists in the field who have never heard of the process, or are skeptical to try it due to a lack of un...

I don’t know how many times I have been told “my boss (management) wants us to be safe, but will not allow us to invest any time or money in a formal safety program. He just doesn&rsqu...

The application range of epicyclic gearing has now become unlimited. As an example, shuttle astronauts were required to break loose some large bolts on an instrument panel during a space mission. A...

Purchasing machinery for cutting gears is an expensive undertaking. In many instances the price tag for a new broaching or honing machine is over one million dollars. When tooling, options, and uni...
