Abstract
Our mission is to manufacture optimum products using provided design data. Thanks to analysis tools brought in recently, the design of more efficient propellers have become possible. To manufacture propellers with maximum design efficiency, a high level manufacturing technology is essential.
The Tamashima Works, is a specialized facility for manufacturing large-sized fixed pitch propellers. Manufacturing size ranges from 5 meters up to a maximum of 12 meters in diameter, and a maximum weight of 150 tons. Here, we succeeded in developing special facilities, the only one of its kind in the world, such as the blade milling machine which can control 5 axis at the same time, the balancing machine, and the propeller overturning facility. These special facilities resulted in higher machining accuracy.
