Product Description
The GMM-80R has a turnable milling head: bevel the top edge, rotate the head, and bevel the underside on the same pass along the plate. For K and X joints on heavy plate this removes the crane lift to turn the plate over, which is usually the slowest part of double-sided weld preparation.
See it in use: Double-sided plate beveling on a shipyard panel line.
