Nissei's Gleason No. 554 Single Flank Roll Tester
One of a small number in the world, is equipped with rotary encoders and a computer analysis package. Rolling quality can be observed and its’ characteristics measured and compared independently in “forward” and “reverse” operation. The parts operate with backlash at the housing mounting locations, duplicating closely the actual assembly conditions. The rotary encoders determine how accurately the gearset delivers uniform angular motion transmission. The errors are treated mathematically by the computer to determine the frequency and magnitude of the associated velocities and accelerations, of interest for noise and vibration quality.

 
Zeiss Three Dimensional Gear Measuring Machine
The Nissei machine is equipped with a built in rotary table, centering column and specialized software. This co-ordinate measuring machine is specifically designed for high precision elemental checks of gear teeth. The surface topography of bevel and hypoid gears can be inspected. Precision index checks can be performed with an optional computer analysis to determine how much of the accumulated pitch error is attributable directly to eccentricity alone. This is helpful in diagnosing applications and manufacturing issues.

 
Klingelnberg Inspection Facilities
The CNC Profile, Lead, Index and Runout test machine is indispensable for any manufacturer of spur and helical gears. The machine is used for manufacturing control and analysis.
