Master Gears

The quality of our gear grinder and gear inspection equipment put us in the unique position to make master gears. Typically customers will come to us knowing what type of gear they would like to inspect with the master gear and then leave it up to us to figure out the specifications of this gear. The most important aspect to master gear production is the ability to inspect and document all aspect of the gear. With our Brown & Sharpe PMM an AGMA 15 gear can be fully inspected and documented. Below is what will ship with your master gears.

Gear Inspection

Besides standard gear inspection equipment Nelson Engineering, Inc. boast a Brown & Sharpe PMM or Precision Measurement Machine. This machine is one of the five most accurate coordinate measurement machines in the western United States and one of only a handful in the world. It repeats within .00002" at 3" and .00016" at 59" and can measure every conceivable aspect of any type of gear. These machines usually can only be found in government laboratories and this level of quality is unheard of in the private sector. Many companies inspect gears on machines such as an M&M Sigma 3 and 7 series machines. While good machines they have limitations in both quality and range of inspection options compared with our PMM. Not only can we inspect the gears but we also use the machine as a fully functional coordinate measurement machine. This means that keyways, slots, precision holes and more complex features can all be checked in relationship to the gear. Truly our Brown & Sharpe PMM sets us apart from all other gear manufactures.
