Certified Master Gears

The precision of our gear grinder and inspection equipment put Nelson Engineering, Inc. in the unique position to manufacture certified master gears. Typically customers will come to us knowing what type of gear they would like to inspect and then leave it to us to work out the specifications of the master gear. When procuring a master gear it is important to realize the most important aspect to master gear production is the ability to inspect and document all aspects 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.

• Certificate of Conformance
  
• Complete gear data dimensional report
  
• Complete gear blank dimensional report

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 gear checking machines only. 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.
