TORQUE TRANSFER EFFICIENCY
___________________________________
The Tsudakoma dual lead gearing system features the largest tooth engagement of any rotary table manufacturer. This generates up to 85% torque transfer efficiency.
OVERSIZE WORM WHEEL
___________________________________
The Tsudakoma worm wheel uses an oversize diameter pitch circle resulting in reduced pressure on the contact surface compared to a conventional gearing system.
CROSS ROLLER BEARINGS
___________________________________
All Tsudakoma rotary tables and indexers use ultra precision cross roller bearings. Four times more rigid than angular contact bearings.
GEARING MATERIALS
___________________________________
Tsudakoma uses proprietary high tensile strength brass to build the gears. This enables exceptionally smooth cutting due to the inherent lubricating properties.
TOOTH PROFILE
___________________________________
Tsudakoma utilizes full depth engagement with a larger gear module resulting in a larger surface area yielding a substantially stronger worm gear system.
