Processes and Factory
Welcome to our tour of the Yamaha water vessel manufacturing division where we use CAD/CAM systems to design and manufacture vessels of all sizes.
Plug Manufacturing --Sprayputty and finishing--
Rough-shaping the plug
After we have built the base wooden core, we spray urethane foam on the completed wooden framework. Then rough-shape it to smaller scale with a cantilever 3-axis CNC milling machine.
Now we apply Sprayputty. Sprayputty is the most widely recognized milling material in America. America's largest boat manufacturers use it because it is the most effective milling material for manufacturing large structures. Yamaha is the only company in Japan to use Sprayputty.
Milling the plug
After the Sprayputty has hardened, we run it through the CNC miller again and cut it to actual size.
Cantilever 3-axis CNC milling machine
This cantilever 3-axis CNC milling machine can process plugs up to 10m long. It has a processing width of 2m, and height of 2.5m.
