CNC Machining

The CNC Router is used to generate bulb and keel patterns as well as templates. For patterns up to approx. 10,000 lbs (cast weight) the router can cut the patterns directly. For patterns larger then that the router is used to cut the needed sections or stations and associated shapes to assist our existing pattern shop. This machine allows the cutting of large intricate shapes cut in single piece or as a group of interlocking shapes (puzzle parts) that make up a larger part.
