Gear wheel

This gear wheel was machined on a Mikroturn® 100 , with 2 clamping set ups, in order to machine the OD and ID. The goal was to replace a multi machine grinding process by one hard turning machine. The gear wheel can be machine considerably faster than grinding, 130 seconds, and succesfully keep the required tolerances.
